Re: help need with 460 problems on new engine
Have you got a new ballancer,, true TDC mark might be out? Did you degree ya cam in, or have someone who knows what they doing, do it for ya.
Might be bad vacum leak, are you using a felpro gasket set, if not you should check for vacum leaks. The only set you should use, is Fel Pro. Best way to check for vacum leak is with vac gauge or a can of carb clean,,spay around carb base gasket and monifold gasket. You will notice increase in RPM if bad leak. Leave vac advance off, no need if ya a steet racer. Missing and poping ,,sounds like too much advance. Check ya leads, resistance check with multi meter. Can't rely on most new electronic parts these days.
Use premium gas only, they go better
Good luck mate.
