I got a buddy that has a backfire problem on his supercharged 454
177 blower, 781 heads, 9.01 pistons (calculated with the heads), blower cam, new hei,
750 edelbrock not modified for a blower, plugs black but tips are white
i was thinking rich idle/ lean under power. it backfires under a heavy load
not sure what plugs he uses, his fuel presser gauge not working but has plenty (according to him)
claims this thing only makes 3 psi :-\ but has no plug in the lower intake to check how much boost
he has if it is only 3 psi could he be too under driven to run??? I messed with a sbc with a 6-71
that my buddy tried to underdrive it to around 3 or 4 pounds and it wouldnt run we had to get it up to 6 to 7 for it to
even run right! NOTE: the valve train and compression checked out out fine tonight
any ideas guys ????
