Ok heres my problem. I have an 83 elcamino that was swapped from a 305 to a 350. It has an edlebrock intake manifold and a mild cam. The engine was rebuilt then installed. Currently there is a white smoke coming from the car, typical at WOT, take off, and start up. At the same time the car feels very underpowered. I cant even do a burnout anymore unless its wet. There is a tapping noise when running, im guessing valves, on the right side. Also after inspecting the manifold there is someting (gas, oil, etc) leaking from the intake manifold as deposits are found around its edge. The car feels like it has more power when its cold, but once its nice and hold it SLOW!! Granted i have a posi rear, but if i floor it and power brake it nothing happens. Couple weeks ago my donut gasket went, and soon after the tapping noise began. Next week i will be installing a whole new exhaust. PLEEEEEEEEEEEEEAAAAAAAAASSSSSSSSEEEE HELP!!!!!!!!!!! I want to enter burnout contest next weekend, but cant with no power hahaha.
