What intake manifold would you recomend? I have a 4 speed, 340 bored 30 over,cam,headers,... has an RPM on it for along time.The waterneck bolts have been broken off more than once I see.I've fixed them,but was interested in mayby something different but not sure what it will do to the motor. It's a street car,driven often.I can't get it to the dyno because of weather but have been told 360+ h.p. @ the fly. I've been thinkn of the Victor series- Victor 340,super victor. Mayby an air-gap RPM? It has a Carter carb,Power brakes,J heads.I just put TTI's headers,x system on.New 1" torsion bars. I'm collecting stuff for braking upgrades too.
What else could I do to help this 340 out?
