If you were to tackle a stroker Gen 3 motor for high hp brackets, what do you think it would make for power? Lets say we go with 426 cubes, 14.5 + compression, best available valvetrain, custom tunnelram, dual Dominators or Termintors with alky, (your choice),vacuum pump, the usual stuff for close to the best that can be built. I am assuming a large bore aluminum Mopar block, or at least a 4.090 bore. Opinions? Last edited by gregsdart; 03/07/15 10:13 AM. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I'm contemplating the switch from BB to gen 3 and checking CL for core engines. Stock block ok? Which core engines to avoid, if any?

Im guessing he has Jesel keyway lifters and rockers. That is probably $5000 alone. But if the engine peaks in the 7000 rpm range, stock rockers and lifters have proven to live just fine. Mopar to the bone!!!

I've heard differently about the rockers. HS is what I've heard he runs Be nice to know what he runs. Matt

You need to move to other sites with a younger group of guys. This place Is stuck in the past. Challengertalk.com is one.

What do you guys think the max HP for a low maintenance Gen III would be? I guess it's dependant on RPM and not HP, so really what's the max RPM a Gen III could live at without having to replace valve springs on a regular basis, 7500 ish?

The Harland Sharpe rocker he uses are done to his specs or design. He informed me that it takes a lot of machining to get them on. Offered to do my heads for them at one thousand dollars, or would tell me how to do it. Told me the T&D required way less work and did not say anything about not recommending them. Of Course I do not know what he does to alter them from production to meet his requirements and have never had a set of production to try on a head. Other people seem to be running them and not talking about having to do mods.

Which core engines to avoid, if any? 5.7 and 6.1 blocks have thin cylinder walls. Have seen them crack at as "little" as 750hp. Most guys want to throw a block away if they have to bore it any more than .020". The LX guys really spend A LOT of time and money tuning them to perfection to get them to hold up under higher hp. A 6.4 block is the most durable of the three. Getting your hands on one is tough right now though. knyech1- '71 Sassy Grass Demon 340/904. Pump gas, 1.61 60ft, 7.439 1/8 @ 95mph, 11.824 1/4 @ 111mph "Not too bad for a pump gas 340, full of used parts and hillbilly ported stock heads." - V.B. '03 2500 5.9L HO 6-spd on 35's. 395hp/755ft-lb at tires.
