hello, 3 days ago, i put a rebuilt 400 chevy in my cutlass. It has a comp cams, 268 cam, edelbrock performer rpm intake, 750 edelbrock carb,accel coil on mechanical advance hei, and exhaust manifolds because i couldnt find a pair of headers to fit it, but that isnt my problem, the problem is, when i first started it up, it ran good, but when given throttle, gas would shoot out of carb. So i adjusted my valves and it ran good, but doesnt have any performance when driving, i nail it and it goes like 20mph, it makes me mad. This isnt because of the straight exhaust manifolds is it? I sprayed carb cleaner around the intake and carb base and it never raised idle, so im guessing it doesnt have a vacuum leak, although my vacuum gauge shows very low and tells me that i have late ignition timing or valve timing. The timing is right on, but runs rough at idle until its at 8degrees btdc. What is my problem, and if it is the valves, whats the easiest way to adjust valve lash? is my distributor one tooth off or something?
