higher compression nightmare!
Few months ago, i go to the local speed shop
to mill my edelbrock head. The compression
went from 9.1:1 to 10:1. Then the car run like if there was water in the tank! I heard
anormal sound from the pipe when flooring.
I decided to do few test and tune session to
adjust fuel press.. as i raise fuel press up
(38psi-70psi!!!) the car gain 0.5 seconde and
4.5 mph. The car do his best at 70 psi. Unfor
tunately the fuel reglator screw didnt go
any farther. What s the deal!?!? i ve never heard that a
naturally aspirated 302 could be running with 70 psi of gas press. All problems are now solved but i just would like to know why the car need that much fuel.
thank for helping
