rejet carb after emi thunder install?
 

Just wondering if I should have to rejet the carb on my 502 after I installed a set of emi thunder manifolds? Its a 502 with a mild cam and it use to be a efi but I took that off and put a dart high rise and a 850 holley on it.

you would really need to do a high speed run, shut right off(no idling) and pull a couple of plugs and read them...to many changes to say exactly what you would need...
