Looking for some feed back... I have a 1970 LT1 M21 4:10 ratio 1970 in a nova. all stock including, air cleaner, exhaust manifolds full exhaust,11 to 1 compression, solid cam with a longer ratio rocker arm, and a smog pump spinning around but not pumping.With a 780 holley carb. My car seems like it could use more fuel. The 202 heads have been ported by machine shop,and bowls have been cleaned up.this is the only wild card. I have the timing set to 8 degrees.Engine has 14 inches of vac. at idle. The primary jets are:78 high flow Power value is 5.0 front and rear. The rear jets are 80 high flow I have a 35 squirter in the primary. Thats whats funny i have been up to 42 and makes no difference, whats going on.... Looking for feed back from z28 guys and deuce owners with similar engine internals to what makes the best torque and horse power. Please help. Thanks todd.
