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.
4 " stroke
I was wondering if any of the motorheads here have any knowledge or know anything about putting a 4" crank in a 350 block with a standard deck.
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 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!!

388 cubic inch small block is a 400 crank with .060 overbore in a 350 block. The rod angle changes so you should get the correct rods. I have done several 388 and 383 like Joe's. Standard deck is correct. The rods are just a little shorter. Summit has a kit that has been turned down. The crank journals in a 400 is bigger than a 350 and will need to be turned down to fit the 350 block.
Summit part number is ESP-B13005E060.
