or is it .040 hmm never been good at math. Really .060 is the max for a street vehichle any larger and overheating my become a issue. Most magazines sell pistons up to .060. (NPD for example)
I'll take a look in my book.
Ok Chiltons to the rescue,
a 352- 4.000x3.50
360- 4.05x3.50
390- 4.05x3.78
hence simple math .050 overbore will give you a 360.

when i was in teh FE forums there was something mentioned called the drill bit test. i thought using that test on a FE motor gives you an idea how far you can overbore (if its a good block) because from a semi educated perspective, a 352 could be bored to a 428, even though it actually cant.

yikes that one is out of my league. When you bore and get new pistons and all that fun stuff for a 352 would a motor loose that extra compression?
because Chiltons says the 352 is a 8.9 motor where as some of the late 360/390's were around the 8.2/1.
