Re: How much HP can a stock 454 bottom end handle?

I doubt there is a better web-site for BBC combo's then this one... I think I read thread after thread for about 2 years before deciding on mine.
Good luck and keep us posted on how it turns out.

I have built a few big block 496 and 454 engines and such that are 2 bolt mains that are at that power level or a little above. Its always better to run forged rods if you can, also put studs in the mains for any rpms pushing 6k.

Re: How much HP can a stock 454 bottom end handle?

Mike, all factory BBC rods are forged.

Where people used to get into trouble were the bad factory shifters. Miss a shift and bad things can happen...maybe the first time...maybe the 22nd time. Missed shifts tended to challenge the stock rod bolts. Automatic cars through 5500rpm and 454s are pretty safe with the stock bolts. 396/427 shorter stroke is less taxing then 454 longer stroke so I'd not be worried about 6000 rpm. ANY shift-thyself std trans I'd be sure to get good rod bolts in there and resize the big ends.

Factory rods order of merit:
passenger car, big end is dog bone shaped
truck rod, big end stays narrow and your thumb fills the gap hence "thumb rods"
factory HP rods, have a 'dimple' more exactly a ZIT toward the small end 3/8 early or 7/16"

Re: How much HP can a stock 454 bottom end handle?

Obviously installing new rod bolts is an easy call but can factory HP dimple rods with 3/8 bolts get upgraded to 7/16 and is it worth the upgrade for a typical street/strip build ? Also between forged and hypereuretic 454 pistons with similar sized domes which would be lighter ?

Re: How much HP can a stock 454 bottom end handle?

Is it necessary to sonic test the block for a 500 ish hp build?

Stan, if you are gonna bore it out, I would have it sonic tested... Not all blocks are the same,some might have had a core shift when they were made in the foundry, jmo...

Re: How much HP can a stock 454 bottom end handle?

Don't plan on boring it out. Just curious if that's a mandatory step to take before building up a big block.

Your block will need to be thourghly cleaned because of your wiped out cam,metal pieces will be all over the inside of your block...
