Love seeing videos with combos like this. I'm slapping together a budget LQ9 shortblock build with leftovers from various previous builds.. Starting with 243 heads and tbss style intake and tb ( gen4 5.3 ) along with multiple ls3 blue and LS6 yellow valve springs, which will be using the yellow's since they are good for .570 lift vs blue LS3's .550 lift. All I'm buying are (or bought) were the x-link adaptor, LS2 head gaskets and after long thought I picked the sdparts LS6 power max cam over tsp stg2 low lift cam. Since SDparts cam was just $239 shipped new vs tsp $300+ and both are close spec'd, seems like it's gonna be a great combo for my 04 Tahoe. I will be using a remanned stall converter good for 2200 stall speed. I'm not sure if I'm going with long tubes as its my DD.. But def. at minimum using shorties and ory to go with my catback.

Timely video...Just today I put the truck intake on the 6.0 going in my 76 C10, going by Richard's videos it got 706 heads, long tubes, and a 205/217/112 drop in cam because it broke a lifter on the old one and I went as low buck as possible. Going for bottom end grunt rather than top end power, because its a freakin truck I plan to use pulling my drag car around and parts chasing in the summer. Maybe next year it will get a bigger cam and a 4L80 but right now its getting a Th400 and a stock 2000 stall. If it makes 500hp I would just about crap myself, because I would not expect it. I do expect it to make a lot better grunt than the 454 sitting on the floor now. I have another one, so it could get some aftermarket heads and a bigger cam to go in my other truck, an 88 C1500 shortbox.

So much great information. Only additional info I wish you'd talk about when you're going over the graphs is what the timing numbers were at. I read so much about timing for the LS2 vs the LQ4 and rec needs less/more timing than that and I really don't know how they relate. Maybe there is no difference at all. I can find dyno graphs for days for my setup but I put LS3 heads on an LQ4 with a 222/230 596/600 cam and have no idea where to go for timing numbers. I've read 16-32 but who really knows haha. I watched your timing video and that was great, just not sure if rec port timing = cathedral port timing and how compression ratio(or lack there of starting with a LQ4) plays into how those numbers move around. I know, I know, verify timing..... Thanks for everything you put out there, longtime subscriber, first time poster.

Hey Richard, you did the perfect test for me! I’ve got an LY6 on the floor of my garage as we speak. For a street truck on a budget I’m going to skip the $2400 TFS 225s and stick with the factory rec-port heads. Reading between the lines a bit, that is 20hp or so better than the factory cathedral port combo. My choice is a BTR NA LS3 Stage 2 cam with a 225° intake lobe. It has a nice amount of overlap, around 5.5° at 0.050, an should work well with a stock converter in a 6L90. Lots of work left to do but come spring it should be up and running. Keep the tons of info flowing!

Thanks for the comment. For me, the “mild” 6.0 has more than enough cylinder head with the stock rec-ports. You can make more power with more cam and head flow, but my truck will be just a driver. If I were building a 415 or larger I’d agree completely!

[@jeffsloane8628]

First of all these videos are great and I know they take a lot of work. Thumbs up and hat tip to you and your team. The LS engine is know for it's broad power band and I've seen so many street driven cars chase peak HP numbers only to be giving up 50+ lb-ft at 1,500 to 2,500 rpm where most street driven cars spend their time. So, my question is could you start your pulls a bit lower, say 2,000 RPM? This would give your audience a much better picture of the drivability they are sacrificing for mid and upper engine speed power.

[@moniquebenavidez9958]

Man the best question on you tube to do with these categories!!!!!!!!

[@MechanicallyEnthused]

Well I am 3yrs back on this comment as just some random dude, but can offer insight for future folks wondering. These dynos put a simulated load on the engine and at WOT that load at so low rpm is going to lug the engine and skew the results of the full pull. Typically on the street your converter/trans wont lock up until 1500-2000 or higher if aftermarket to let it get into the power band. Another example is if you're in say 2nd gear rolling at low mph and try flooring it. It's going to lug and feel like a turd until it starts making power, then it'll "wake up" and pull. Horsepower is measured based on torque and RPM, so the accuracy is better when you have the motor spinning up. Also these LS motors specifically, really don't start making power until the 2500-3000ish range anyway, so it is going to show really sad numbers until it starts eating some air and farting out power!

hendo337, it’s not going to be a budget build, it will have all forged guts anyways. I’m looking for no less then 1000hp to the wheels thru a built t56 in a 93 f-body. The real debate is ditching the 6.0l and buying a lsx block instead.

[@SF-wu2mp]

hendo337 I was leaning towards the gm 376 lsx block if I did end up going big. Because of the 6 bolt head capability. I’ll look into the dart block tho. I originally looked into boring and stroking my lq4 but read about when you stroke them the sleeves aren’t really long enough and you get some piston slap, combined with boost the over bore from the stroker kit also takes meat away from the cylinder bore making it more likely to push the heads up or blow the head gasket under high boost. Atleast that’s what I read online so take it with a grain of salt. But your probably right I’d be fine with the lq4 and stock 317 heads with forged guts for the power level I want but you know the old sang goes go big or go home! Be nice to be able to push that hp goal higher after a while too so I was thinking ahead too.

Factory untouched Ls3 heads and intake manifold don't make as much power as TFS heads and FAST intake manifold but think about the price difference.

[@ze_german2921]

I just had my newly acquired 706 heads cleaned up with .570 springs and a BTR Truck V2 Stage2 Cam for my LQ4. Also topping it off with a TBSS intake. Cant wait to see what my Butt Dyno registers.

I dig your Commodore avatar. Kudos!

[@DBSSTEELER]

Be honest with what you want to do with your combination and pick your parts for the combination from there. Most of the power difference between the stocker rec port head and that trick flow head is on that particular block you’re giving up a four point compression which is why I think Richard mentioned compression in the beginning of the video.

Hi! Looking to do a LM7 stroker 383 ci Would really like to see compared to 6.0 or .2 Thanks

[@Techangler65]

Great filing system, you can find what you need lol Great job sir

9 months later and youtube brings me back here but this time with my wife watching with me. Now she wants me to be on the lookout for a 6L. I have an empty engine stand that i planned to build a 4.great but thats getting pushed off again. No idea what i would put it in but my wife is giving me the green light to build another motor. 😂 I think she is hoping it ends up in the c4 vette for her. Hmm would be sick. BTW the ea888 build is on hold, due to backorder main bolts and ups lost my thrust bearings/washers. In the off chance you remembered and were curious.

Good stuff love it

[@BigHeinen]

The biggest takeaway I get from this video is that the single biggest power adder is a good cam. Unless you are only worried about power above 6,000RPM then just change out the cam. All your usable power is from 3,000 to 4,500 where we all drive every day. Port match your intakes to your heads, degree your new bigger cam and go drive the thing!

[@zachariahmagallan5738]

What would you recommend?

[@zachariahmagallan5738]

I'm trying to pull a 44ft fifth wheel.

[@BigHeinen]

@@zachariahmagallan5738 In the past Richard has recommended the BTR "Truck Norris" cam for it's low end grunt.

[@zachariahmagallan5738]

Ok I'm a new b what does port match your intake to you heads and how do you degree your new cam when I watch cam swap videos all I see is them pull the old cam put and slide the new one in

[@Kovemaster_69]

Richard i appreciate your videos thanks for this informative content.

[@richardholdener1727]

Thanks for watching!

[@jameslong5964]

A lot a good real test results!👍

[@jamesthemachinist1325]

I’d like to see a head to head of a 5.3 stroked to a 6.0 vs a lq9 .

[@cargotoolshop5319]

No comparison because of the smaller cylinder diameter
