I have an 1992 Chevrolet S-10 Pickup. I recently just put an 1985 Chevrolet 305 out of a camaro into the vehicle. I put a new cam in the motor, along with lifters, and pushrods. I left the rockerarms loose a little, i was going to ajust the rockers while the vehicle was running. The motor turns over fine, none of the rockers are to tight, and like every 15-20 engine revolution, i will bend an exhaust pushrod. Every time it seems to be a different pushrod. I dont no what to do. I tryed messing with the distrubitor and nothing seems to be fixing the problem.

I NEED SOME ADVICE
