How high of compression ? |
By K-SKI - 06/30/2004 10:52:05 PM; IP 65.166.114.50 |
I'm wanting to build a 390 for my f 100 and I'm stumped on what I should use for pistons and compression with stock 352 heads?
I'm going with Comp Cams XE262 or their 270 magnum cam with 650 carb, performer intake, headers, 2 1/2" exhaust. The truck is 4-speed with 3.50 gears.
How high of compression ratio can I go with pump gas? Around 89-90 octane.
Please any ideas or replys welcome! Thanks |
