alright newly rebuilt 355 ... plugs show its running rich, now im just wondering if i can get away with going to a hotter plug or if this will need a tune on the carb?? i bought the cheapest (and probably the coldest plugs) i could find... the carb is a Q-jet.... oh and i just recently got done breaking in the cam and i still dont have exhaust hooked up , just coming right off the exhaust manifolds... should i wait and see where the plugs are at after i get the exhaust hooked up? or will it not have much of an effect?
thanks in advance for help, i just dont have anyone around that i can go and talk to about all this so all help is much appreciated!
