Yes, checked with a dial indicator last night and a digital calper (.105).

Ironically, my 69.5 440 for my RR is also .105 in the whole. I've heard this is common for the 2266 pistons on a 440.

I was thinking of using the KB162 piston, even though they are not spec'd for NHRA. Decking the block, etc, etc, could get expensive and if I get too much in the motor, I may as well up the compression and go with stealth heads, etc.
I may pull a piston/rod assembly out and compare them to my buddy's stock motor. Its just now been assembled.


NHRA doesn't exactly run events here in KC, but I thought it would be cool to see what a "stock" 383 could really do.
