As far as I know, you can order a 302 crank from Chev. Smokin hot revving engine came stock in the 68 Camaro I think. Drops right into a 350 block.

A guy at one of the machine shops told me how they have done several 4 by 4's , as they call them. I didn't pay it much mind at the time .
But I missed out on a 400 block on ebay the other day. I also looked at a another 400 block at a second machine shop that was being made into a 434. He told me the compression height on the required pistons was only about 1 ". Thats WAY too short of a piston for me.
So I wondered if any one might have any good tech info on a 4" crank install. Can it be done with a 6.0 rod for instance?
thanks Jeff
I stand corrected.RayO said:I think that would be extremely hard to do without a VERY short piston, get a 4" stroke on the crank I mean, especially with a 6" rod. Even for a 383 stroker the stroke is only 3.8", and the block has to be notched for that.
As for the crank out of the old Camaro 302, that is only a 3.0" stroke, that is why it rev so fast, the short stroke and the same 4" bore of the 350 that normally has 3.48" stroke on the crank.
Good luck!!
