what is it

i have been restoring my 67 rs camaro, got the body almost done so i decided to start on the engine. i took it to my machinist and he didnt know what i had. he said that the crank was offset ground to run small rods. the mains are ground .10 under and the rods were standard. my question is what engine do i have and is it worth rebuilding. it ran just fine. i wanted to freshen it up.i know the block is a 350 and so is the crank.what would be the advantage of running the smaller rods. is this going to be costly to rebuild or should i just run it.

Re: what is it

Is it a forged crank?What is the casting number?At one time you could only get .030 undersize bearings so if it was a forged crank and had spun a bearing you could grind it down to 2.00 and run small journal rods to save it.It it has been offset ground also it would be a 2.58 stroke instead of 2.48.Either way it wont cause any problems you just have to get the right bearings.

Re: what is it

it is a forged steel crank. the guy i bought the car from used to race it. he retired so i bought it. the block is 60 over with 12.5to 1 comp.it ran really hard.what cubes would that make the engine.i kinda want to keep it running in the car.

Re: what is it

Assuming its got 5.7" rods, and the stroke is now 3.58 with a 4.06 bore it would put you at 370.7 c.u. with stock height pistons.

Re: what is it

I know a lot of the race engine builders like using honda rods in sb chevy's to reduce rotating weight. If the previous owner ran it that hard, maybe some trick parts got installed....
