I have a '68 292 L6, bored .030 over, w/ stage II Crane cam and 1.84 intake valves. I replaced the old 390 CFM Holley with an Edelbrock 1404. I can't seem to get it to idle smooth at low RPM. It floods and then starves. I've regasketed the manifolds twice, installed some studs and/or stainless capscrews on intake [Offy] and headers [Clifford], reset the timing to TDC, checked gap and dwell swapped out the coil and rewired the plugwires. Fuel pump checks nominal at 4.5 PSI. It still won't run right. I'm doing something wrong, but can't find it. Tomorrow I'm gonna put the Holley w/ new 7.5"Hg power valve back on and see what that does.
