What is the STD bore on a 502?
Depending on where I look, I see the standard bore on a GM 502 is either 4.466 or 4.47
I am trying to make mine a stroker, but don't really care to bore the cylinders +.004 (if I am going to bore it would be right up to 4.5). But I am on a budget and would like to keep the block away from the machinist for the time being. It's a brand new block, otherwise it wouldn't be a question.
To make it a stroker, I already have the 4.25 crank, and 6.385 rods. But I need new pistons with the correct compression height. I can't find any maker of 4.466 pistons for the longer rod, but many make 4.47.
I would like to get this build underway and don't want to be set-back by anything once I start wrenching. Please let me know if any of you have stroked your 502 without boring, and who makes the pistons? Keith Black is probably where I am leaning for my budget build - they make the 4.47.
Thanks for your help
on small cars yes. but fat fender cars are pretty much the same in size and weight as the donor car. i found s10 brakes work great on fat fender and pickups. a deuce will just need manual brakes...
Time for brakes
