1988 Formula 350. Freshly rebuilt, added Dougs shorty headers and converted from auto to T5. New flywheel, clutch, and balancer. Started right up ( made damn sure dist was stabbed correct) and sounds good. I did put a Howards cam in it as well and forged lower end. Took it for a drive and has quite a vibration, even sitting in it at idle and revving it it will shake the dash a little. Now, I have never built an engine back to anything other than stock, so wondering if cam and headers can cause this or if I just have a miss. Verified all plug wires, cap and rotor and ICM are new. Going to install the FiTech 38350 on it once I get it sorted our. Zero smoke either. I had the block bored 30 over and heads gone through (083) but I put it all together. No knocks, or anything either. Maybe I am just worried for nothing. Oh yeah and new motor mounts and tranny mount. Stock Intake and new 22lb Southbay Injectors Thanks alot guys!
