Thread: 454 build up

Tweet

I was in the hunt for a 454 and found one that a friend has that he never used in his project car, he said it has a spun bearing. i am planning on building this motor for a goal of 500 horse, what is needed to do this and is it worth buying this motor, he said he has a pair of 396 heads lying around that he will toss in with it.

Thanks

when i started to plan for my bbc build, i grabbed a book on Chevy Rat Motors from the parts store. I've learned alot from reading that book. 500hp is easy to achieve with a big block.

Was it a rod or a main bearing??? Neither is that big of a deal, of course it will require a regrind on the crank journals, and if it was a main that spun, an align bore and hone would be in order too!

yep not big deal if it hurt to bad evey thing just gets shorter if hurt to bad rods get shorter and crank to cam as well and then a line bore timming chain set .but that was back in 9-16-009 he may have past on it
