Help on New C.R. w/ 390X Heads
I just installed a set of small chamber 390X heads on my 1978 401 with stock dished pistons. I believe stock compresion to be at 8.4 to 1. The best I can calculate using on on-line calculator I should now be at about 9.5 to 1. I'm wondering if any of you smart guys would know for sure?
