mustang 429 engine swap

  1. Classic Tech
    I just swapped a cleaveland for a freshly rebuilt 429 in my 73 and am having some minor to moderate vibration as I rev the engine. This is in park, not driving. Any help would be greatly appreciated. 429, edelbrock performer intake, cam (hydrualic), and 750 carb. Scorpion full roller rockers...
