Gen 3 max effort hp? - 03/07/15 01:46 PM
OK, this is a fun post for those guys stuck inside, and insomniacs like me. 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?

Aluminum block large bore 3.79 stroke Thitek heads.
Spine the thing to 9000 rpm and I believe 1000 hp will be obtainable.
Dave Barton has gone 148 in his 3300 lbs challenger which is 888.88 hp

Stock blocks are fine N/A aspirated. I know Bartons tach hit 88-8900 in one of his in car videos. 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.

Barton worked with T&D for his gen II rocker system. They may have used HS until T&D came out with theirs.

Digby's Dart or the Goss Challenger are just two examples of late model Hemi getting it done.
This site will never be a Gen 3 tech hot bed. You need to move to other sites with a younger group of guys. This place Is stuck in the past.
Challengertalk.com is one.

I agree with Matt, Max effort, money no object, dropping a blank cheque off at RBRE and telling him to go nuts I think you could get 1000 hp, but it would be very high strung. 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?

Barton is using stock gutted lifters and Harland Sharp rockers.
He is not a fan at all of the T&D or jesel stuff

I contacted Barton last week about buying Harland Sharpe rocker for my build. He gave a very long reply. 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.
