Awesome Ben keep this going its so much different now with KZbin. I'm 53 and in Australia. When I started fooling with engines back in the eighties information like this was impossible to find. Great too see many experienced guys like you passing on things you have learned.

[@Bbbbad724]

A lot of FE guys are using 4.08 bores and 4.25. stroke on the FE and depending on the cam and they can make 585 hp and 545 ft lbs NA on 93 octane. Safety, and with Trick Flow heads and good quench and some of the tricks you have taught us. Those numbers were with less than 10:1, imagine tightening it up and going to 11.5:1. Maybe 4.09 bore or even 4.1 if it sonics, I think 725 hp and 640 ft lbs on 93. This is on an FE. With a tall deck, a 6.8 or even 6.9 rods can fit. People say that rod length doesn’t matter, but I want as long as I can get for light weight pistons. This is a great street/ strip combination. I wish I could build a 427 at 425x 3.78 engine. But the strokers are strong and they have years running them. Barry Rabotnik brought the concept to the FE community and we found that we had the perfect cores for this geometry. I have built 4.096x 3.784 that is right at 400 with 6.85 rods light pistons and.650 lift 256@.050 flat tappet when they would live, and put it in a 66 Mustang with the front cut up, and it would wheelie and do 9000 rpm’s using a 360 truck block which the 3 point reinforcement and cross bolt mains on 2 and 4 and well balanced. He ran that engine that hard and never broke it. He sold it to a guy when he retired the car, and they built a stroker, less hp because rpm dropped to 6200 and a bunch more torque. So I can say that what you’re saying is absolutely true, whether Windsor, FE, or 385s. Budget how much can you spend and what kind of use do you plan for it. To hear an FE at 9000 like an old Tbolt, or a 511 stroker at 6800 you hair stands on end!

[@markmccarty9793]

That stuff is gold now! Do you really want to risk scrambling vintage parts when you can just buy a Dart Windsor block and make more power! You can build a reasonably priced 408 that will make big numbers, and if it breaks, just make a call? We're talking 40, 50 year old engines here! I'm 63! The restoration value vs. the actual performance doesn't add up! But, it's yours!

[@Bbbbad724]

@@markmccarty9793 I can’t disagree from an economic standpoint, but a 4.125bore 4 inch FE is possible with many 70s 360/390 blocks and they used premium iron for them in order to be used only in trucks pulling trailers. They weigh 20-25 lbs more than a block in 60s 390s. They weigh the same as a Super CobraJet block. I have a trove of them in the shed that have been seasoned for 20 years. The have the same triple web reinforced mains. Also I have a pair of aluminum cross bolted main caps and ARP main studs for all 5 mains. The two aluminum ones are for 2 and 4 on each side of the thrust main with oiling passages you can feed the crank oil in the middle of the crank and at 2 and 4 at high rpm those two are most likely to crack, and feeds in the center fully send oil to the front and rear along with the cam oil to the mains like a SBC always has. I have a deep Canton pan and a 3/4 inch pickup tube. I also have a set of heads and intake to provide 1.6 hp per ci from the 427 and the same torque, about 1.5 per cube in a wide range on 93 octane. Good old nasty FE goodness with a roller cam, solid of course. And a nice fill to the top of the core plugs. I d rather use up what I have than start over. The crank is good Ford CJ iron well seasoned and cut down to 2.2 rods for BBC 6.7 Molmar forged steel. 4 inches. That’s 1.67 R/S and 10.6:1. 7500 rpm safe 4.125 flat tops with metric rings. I want the whole assembly to turn at 15 ft lbs with the plug s out, and my standard 25 psig at 1050 idle and 80 at 7500. Never heard of aluminum cross bolted oil feeding main caps? They run right off the filter mount and I have a cast iron 3 cap saddle that fits those studs if I want 8000. All I need are pistons and rods. I know a guy…..lol. 684 hp and 642 ft lbs on pump gas.

[@benalamedaracing2765]

Brandon, thanks for your support and appreciate it much. To clearance I install the crank and rotate with one rod/piston without rings and mark where it gets close to the cylinder wall to the rod bolts! This will give you the exact location where you will have to cut to clear. After clean it up with a sand roll so there will be no sharp edges to damage the piston skirts. There are numerous 408 and other 4.100 and 4.170 pistons out there except this big 4.250 crank there are very few pistons available if at all any. I am sure Ross and JE can make you custom to your specification.

[@AmericanThunder]

My 332 has a 3.25 stroke, and 5.5" h-beam rods in it, so the r/s ratio is the same as a stock 302(1.69) in order to do that, I run custom JE pistons with free floating pin, and oil ring support plug, I have ZERO oil consumption, so JE's system is working good.

Hi Ben. I appreciate you and your great information. I was wondering about clearance to camshaft. I built a low buck 3.85 stroker and clearance to cam lobes was tight. I realize racing rods have more clearance in that area, but it's hard to believe you can fit a 4.250. does it require smaller base circle cam? How about a video showing that part, and a little info about when you'll need a special cam, who you get it from etc, or is it just that a roller cam gives it enough clearance already?

[@benalamedaracing2765]

Ok thanks for the suggestion and I would mount one of my blocks with a camshaft with stock base circle diameter. It fits without any major issues. Will do this and it is an excellent suggestion!

[@CLEEPER1]

Great video Ben. So for a street motor you prefer over square to under square for same cubic inch for rpm reasons? I am looking at doing a 5.3 Ls bored to a 5.7 and thinking about if I should stroke it to a 383. It will be my street car and will keep rear gear to a 3.70 so the stroke will be better off the line and keep cruising rpm down

[@benalamedaracing2765]

Chad, agree with you and an increase in stroke is therefore an increase in displacement! You cannot go wrong and actually today's modern engines actually show more stroke than bore so they are under square with good performance!

They recommend the smaller heads because they are not engine builders or competition experienced in the sport or racing. With a 408 on boost i would run the 220cc and you would be happier big time! If you can use a 6.250 rod the better if possible.

[@benalamedaracing2765]

351C 4 bolt factory block is still weak around the main cap webbing and I had issues with those! Now on turbocharging, as long as you are not lean or on the edge of detonation the block will easily make 900hp! Turbo is actually safe and easy on the bottom end because the boost does not come early and hard compared to superchargers or nitrous oxide which hits the bottom end early and almost instantenously on the bottom end. Turbo's comes in gradually which helps the bottom end big time! Within reasonable limits of boost plus intercooling on the streets your friend should have little concern as long as he does not overdo things.

Hey Ben. Do the pistons maintain good stability with that much skirt sticking out of the bottom of the bore? Guys in the LS world talk about a 4 inch max stroke for piston stability unless you add sleeves.

Evan, this is why I ran a long 6.250 rod as opposed to the 6.200 or shorter used by many out there. Second, LS engines are if I am correct deck is at 9.240 which is rather short for a long stroke and you will run into the piston showing the pin on the bottom of the stroke.

[@benalamedaracing2765]

What I am referring to with the larger stroke has an advantage when a car has some weight but is "limited" in ultimate rpm potential but possesses more torque @ lower- mid range rpms! This is why it needed more converter stall when it went to a 4.00 inch stroke. On the stroke comment it is the same. The bigger stroke has less potential "rpm" therefore limiting itself @ high rpms, also every time you have placed a larger stroke crank a shorter rod is the after effect because if you do not do this the piston pin will intersect the oil control rings this is why you see I have as I pointed out some metric ring package to allow this combination to work.

[@benalamedaracing2765]

@@mistersniffer6838, you are getting confused so it is ok let me explain again. When you are building street and race engines and move over to extreme racing engines there is a crossover point where lesser cubic engines actually produces more power where it is needed at high rpms! What I am referring to is the "street car" shifting at 6800 rpms did run low tens! However, when I destroked it and lost all the mid-range power and everything went upstairs I regeared it lower with a much higher stall converter. This produces a lot faster car and the more obvious if it was lighter. Imagine if you installed a big block inside a F1 car and went racing? It will not go anywhere but spins its tires and end up limiting its ultimate potential high rpm power! This way F1 or indy cars run "over square" engines under 2 liter or thereabouts depending on the rules) with lots of rpms but these short stroke big- bore combinations was installed in your moms station wagon it is a sitting duck! You can have the exact same engine size one with a long stroke small bore and the other big bore short stroke it will be a massacre depending on the type of chassis or race car you are trying to build. For ex. 4.125 bore x 4.00 stroke= 427cid small block 4..060 x 4.170=429 cid. Both engines similar displacement but will react very differently using the same compression and camshaft. This said, run a Yamaha Kawasaki-Honda all big bore short stroke and watch the tach against a Harley and look at their rpm range! Very different even thou they all displace over 1100-1200+ cc's. Geared differently as well...

Would you be willing to share the Ross custom piston spec sheet? If so, I can give you my e-mail address.

[@benalamedaracing2765]

The number at the bottom of the pistons are 102647 D. The crank I forgot who made it but the numbers are as follows. 35142506250 INT 1920

@@benalamedaracing2765 Thank you

Your oil scraper rings gotta be in the edge of the wrist pin hole? With 4.170 stroke and 6" rod.?assuming a 4.04 bore

[@benalamedaracing2765]

These are a concern and I use a metric ring pack and minimum 6.250 rod. You have enough deck height to use a 6 inch rod is not recommended..

Wow that is a stout number you got and it should haul butt! Did my videos help with the build?
