If I recall, there are several of them Rich did. One on a 306ci shortblock, then on a 331, then a 408, with increasingly sized intake runners. Highly recommend "Dyno-Proven Small Block Ford Performance" by Richard Holdener. Some fantastic information in that book!

I run this cam in my 89lx because of the article in MM&FF you did yrs ago on cams where you swapped a ton of them in a test motor on the dyno. I ran ported stock heads for awhile and until i got a good deal on a set of Canfield 192cc heads. Which you never hear about anymore, but were sweet back in the day. With that and the ported GT40 intakes it runs pretty good! Of course i've had the car for over 20yrs now.

Interestingly, your "favorite" XE 274 HR cam is so close to my preferred all around favorite go to cam for both SBC & SBF, which is the XR 276 HR, (which are offered in both 110° & 112° LSA, but sometimes is listed as XE 276 HR, especially when a 112° LSA grind). Both the 274 & 276 are close grinds, but obviously different, which in truth can make those differences in a specific build. I am a GM guy 1st, & Corvette guy in my heart & soul! My brother is a Ford guy, go figure we should beef with each other right? Well absolutely not, & actually not only do I like Ford & he likes GM , & because we both have been building high performance engines & high end custom cars for over 20 years now, & so we can both see, admire, &/or admit the pros & cons of each, & also other brands. Honda makes great cars! Also a 500hp 4 cylinder is bad ass! Back in the early to mid 90's I had a 84 Camaro, in which I took the stock 305 out & converted it to a 350 TPI & took the IROC-Z body kit from an 87 or 88, oh & added a Richmond 5 speed. Eventually that wasn't enough, & so built the engine up to a respectable 485HP / 460TQ , which was alot in those days. Not much could touch me, "my muscle car". Until I lined up with this 4 banger Honda, & I laughed, thinking this poor kid doesn't have a chance. I had him off the line, my torque couldn't be matched, but within a short time I heard the spooling of those turbos, the tell tale B.O.V.'s & he was gone! It was embarrassing. My bad ass black on black, blacked out (murdered out, before that term existed ) Camaro just lost to a Ricer, no way! Well it did, & after talking to the guy, & opening my horizons, & so I left my prejudices behind me. Learned to respect any car, & any build, etc when it deserved it. Same with the Ford thing, when your a Chevy guy, & you tear down & build enough of them & compare characteristics & differences between the two, you can actually understand respect all of these. The SBC & SBF are great engines in their own right, both had their flaws in their own right too.

Great work @Richard Holdener, I love seeing features on the old 5.0. I am running a stock bottom end 87 HO.

As far as the power levels. They are similar to my real world experience short of power adders.

AFR 165s, E303, 1.7 rr, tube GT40, 70MM TB/ anderson power pipe made 278/300 ish. The switch to a Holley Systemax and accufab 75mm made 330/335. -Swapped out the E303 for TFS1 and 30lb injectors 338/365. All on the same MAC shortys and new Flowmaster 2 chamber cat back.

[@lightnin83gt10]

I love the basic combos and comparisons! Mostly because that fits my budget. But the one overlooked comparison is modifying stock heads for performance. I don’t have $1200 for aluminum heads, but what I do have, is a pair of 70 351w, and a set of 66 289’s and maybe enough sense for some home porting. Lol.

I started with rebuilding my short block and added a lunati cam with 544/560 lift 232/242 duration on a 108 centerline, added twisted wedge heads with Harland Sharp 1.7 Roller rockers. Saved money up and then added a GT 40 intake and a 75 mm accufab throttle body with a 70mm mass air meter. After breaking valve springs a couple times I then changed cam out to a blower cam and added a procharger with an air to air intercooler. Had 13.5 lbs of boost. Don't know how much power it was making but I could blow the tires off really easy at 50mph lol I also had a crane intercepter II to tune it with. Still have the car today just like that. Have a 93 GT with same setup but has a kenne bell on top of it. Not a comparison in power the procharger way stronger.

Thanks so much for your content.

[@timothybayliss6680]

Comp used to sell adapter studs that were 5/16 on the bottom and 3/8 on the top so you could put adjustable rockers on without machining. Most guys just bit the bullet and went aftermarket because the investment into machining a factory set of heads if you needed a valve job would get you half way to a cheap set of aluminum heads. I hated using shims to set lifter preload, what a hassle.

[@jaceyrondeau8133]

@@timothybayliss6680 l know exactly what you're saying. Who wants to invest any money into E7s. I'm not even a fan of gt40s. There are so many great aluminum heads produced now.

Besides a valve spring upgrade and stem seal replacement, I wouldn't waste money on stock heads. Thanks for the response Tim.

Great video Rich! I actually read, read, then re-read your "Dyno-Proven SBF Performance" book and chose this cam for my first 347 build because of it. With ProComp 190cc heads, an air gap intake, about 10.5:1 compression, 1 5/8" headers and a 750cfm carb I ended up going 11.31 at about 117mph at 2880lbs race weight with that combination! I actually followed another combination of yours shortly after with the same short block, AFR 205 Renegade heads, a Victor Jr intake, XR292R solid roller, 1-3/4" headers, and a 780cfm carb. Ended up going 10.84 at 121mph with that combination at roughly the same weight. I'm a bit of a SBF addict! Love seeing different combinations and dyno curves from various setups. I currently run an old school iron-headed Boss 302, which doesn't use a lot of off-the-shelf parts, but I love that aftermarket parts availability is thriving for these engines. Keep up the great work!

[@albertgaspar627]

Yep, once you take the 302's small ports and valves (which made its famous torque) off it, you've got a short stroke engine wanting a lot of revs to make its power higher up the graph. What also seems to hurt a 5.0 block is a power adder kicking in around 3,000 RPM, the fuel injectors may not be adding enough fuel that low if there's too much boost or nitrous needing fuel to burn and it isn't there until after 4,000 RPM.

[@JamesJohnson-tj9pv]

Awesome information -

[@theauthenticsteve]

Just watching this now but it's funny that Richard says shorty headers are worth nothing when Ford Australia proved they are worth exactly 10kw which is similar jump to the long tube headers in this video. Richard could make a video just on the different AU Falcon builds as an example of what to expect. Standard AU Falcon 5.0L motor with GT40P heads and explorer intake and 65mm TB and similar to stock US cam and 9:1 CR made 175kw XR8 AU Falcon was the same motor as above with the only difference being shorty headers from factory 185kw Then the T1 TS50 had a bigger cam with 210 duration and Y303 heads with 1.6 roller rockers and made 200kw The T1 TE50 and S2 XR8 swapped the ally heads for ported GT40p heads and made the same 200kw The T2 TS50 and S3 XR8 changed the cam for slightly less duration but increased the rocker ratio to 1.7 and went to a 70mm TB and increased CR to 9.4:1 for 220kw The T3 stroked the engine to 5.6L, increased the compression ratio to 9.6:1, cam was similar to 200kw with slightly smaller LSA of 116,, RR was 1.7:1, TB increased to 82mm, ceramic coated headers and the best intake manifold ever produced for a EFI Windsor with shorter runner length made 250kw Herrod took the above motor and swapped 4/1 long tube headers, put a cam with 216 duration .505 lift and 115 LSA and a tune and made 300kw with that package. Interestingly there are many reports of Aussies who tried those 4/1 Di-fillipo long tube headers used by Herrod against Tri-Y headers and all say the long tube headers lost power down low for some power gain up top. Those long tube headers are no longer made and that manufacturer switched to tri-y headers. So a few takeaways. Shorty headers do increase power over standard exhaust by about 10kw. Long tube headers can also increase top end power if the shortys are acting as a restriction at higher power levels. Ported GT40p heads can make 400hp. You don't need a big cam to make 400hp but more cubes and a killer manifold help. I really want that Tickford manifold or better yet the entire motor it came on.

[@richardholdener1727]

SHORTY HEADS HAVE NEVER SHOWN THE POWER GAINS YOU MENTIONED-I'VE TESTED THEM MANY, MANY TIMES

[@theauthenticsteve]

@@richardholdener1727 As I said these were factory models by Ford so there are literally thousands of examples. The only difference between the 175kw motor and the 185kw motor was the exhaust. Those were the factory rating by Ford, I've owned and driven plenty of them, the 185kw is quicker than the 175kw in standard trim, put the XR8 exhaust on the standard one and I can't tell the difference.

Richard, I can see this from your side, but testing each of them, singly, in the test configuration would give each mod a specific and discrete value. Yes, the numbers, as you combine two or three together will come out higher.

Just had another challenge idea. I’m going to be running an xe274hr with a set of Systemax heads that have been professionally ported and milled to achieve 10.5:1 compression. That being said, I was going to get Ed Curtis to build a camshaft for me but he explained that the springs I have wouldn’t work with the camshaft he’d build for me. I’d already spent $300+ on beehives and components to use them so I dipped out. Just curious if you’d be interested in doing a custom cam dyno test vs your favorite camshaft.

[@richardholdener1727]

it is easy to make more power than the XE274HR cam

Not bad for how cheaply you can come by one, it won't really make a car fast but 300 lb/ft available from damned near idle is enough to have fun if you're angry enough with the loud pedal. Cheaper and easier to work on, too. I've spent a lot of time over the past year wondering why I bought a German car. :lol:

the trick flow stage 2 is similar and costs less, it is basically a crane cams part. used it in a 331 build for both efi tfs-track heat and carb air gap,makes for a good street cam, with 3.73 gears makes lots of decent low end and mid range power with tfs tw 180 heads and 10:1 compression for NA use, also consider smaller chamber heads for NA since allot of 5.0 pistons are below deck and a short stroke it call be harder to up the compression, gasket selection should also be considered.

[@gregwilliams4380]

I like the XE282 better then the 274 but still similar.

[@johnparrish9215]

Mr. Holdenter, a Boost/Engine theory question if I may: If maximum torque is the maximum VE rpm of the engine would you say that increasing boost by RPM past this point in order to create a perfectly flat torque curve is possible with out over stressing the engine??? In theory your 622 hp at 5800 would have been 703 hp at 5800 if the 637 pound feet of torque could have been maintained at 5800 rpm. It's an interesting concept that might be fun to play with.

[@timothybayliss6680]

This is how modern manufacture create the flat torque curves. Mercedes has their biturbo v12 but the transmission is limited to 737ft lbs of torque. You will see lots of German cars that make the same torque across a rev range and the ecu is manipulating the boost and other properties to keep the output from the torque limit of the transmission or to the rated output. Lots of time a reflash on these cars makes huge midrange torque. What your saying is right. You can manipulate the boost curve to maintain the same output torque over a wide rpm range if exceeding that torque may be harmful to components.

[@bcbloc02]

Still waiting for the comparison of turbo long tube headers versus same flowing log manifolds. Curious if the back pressure from the turbo effects the long tube gains. Would also be a good test to run a fixed dyno load amount and measure the time to accelerate between the two to see if the long tubes add a bunch of turbo lag in normal use.

[@Diondo26]

good to know ..just build a 331 cu and if your are right ..it will pull close to 400hp ..nice..also waiting for the Head test ..

[@bugsoli]

Nice job Richard! I would love to see a test with your GT40 intake and a set of iron GT40 heads (the real ones, not the GT40P) with this cam as I'm building my 302 with GT40 parts but don't know which cam route I'm going... Keep up the great work and long live to all American V8s 😉

[@frankg5076]

you may need to upgrade the valve springs and rear end gears for that cam consider the TFS trackmax stage 1 cam the stage 2 is similar to the 274xe.

Great work Mr. RH! Thank you for answering the HP advantage of a shorty vs long tube header. If I've learned one thing from RH's channel is to max your NA engine combo and then add boost. When adding a turbo system, should one attempt to run long tube headers, or focus on an exhaust system with min bends and a direct path to the turbo(s)? The SBF (302ci) block splitting problem, is this limited to roller lifter blocks, and not an issue with vintage (1968 to 1978?) hydraulic tappet blocks? If building a track only, high rpm (5k plus RPM) combo, what is the boost/HP limit? Thank you.

Heads and turbo

What is my favorite 302 Ford power modification? - Push it until the light weight block splits in two right down the cam tunnel !

Richard I’d love to see an Olds 455 build. I don’t know much about them but my dad had one in his jet boat. I always loved the sound it made. Tunnel ram maybe?! Thanks 😊

[@muskyelondragon]

Wow this is a hell of a test!

[@juanf4739]

[@TerryByrdJr]

I need this video for the 4.6 2v Big Fella 😁👌

[@DR-br5gb]

Awesome Tests Richard!

[@hopeandrelax]

Thank you for the 5.0 video. Can you make a video on how to do ring gap ?

[@richardholdener1727]

how to measure or how to cut them?

[@hopeandrelax]

Richard Holdener both would be amazing

[@scottschilling127]

Great bolton buildup video. How about a gt40 vs gt40p Head dyno comparison. Heads straight out of Junk yard. Limited prep clean, psi test, valve springs and seals.

I'm a Chevy guy, so I've never understood the reasoning of those wierd shaped intakes. I guess it's a low profile way of making long long intake runners?

[@trevorvaughn5562]

View This Yep that’s exactly what it is, long runner+low profile

[@jonathanduke8295]

Thank god there is hope for power in my Mustang Gt
