I have a 1973 360 Engine currently installed in my 72 plymouth road runner and it has a Edelbrock performer intake, performer 600 carb and a comp cam that is matched to the engine, the bottom end is basically stock with around 9:1 compression although it has alright power now but I am like everyone else and would like more, and I am interested in if I would improve anything if I decide to add a performer RPM intake and a camshaft to match it do you think that making this change would improve anything at all or make it worse
Would be interested to know what gear ratio, exhaust system and cam you have right now.
Is it an automatic or a manual trans.
It has a 727trans 2500 stall converter and 3:23 gears the cam is mild I cant remember the lift and duration for sure but I think its 212 duration and 440 lift
oh and it has headers and 2 1/4 exhaust with xlerator turbo mufflers
stock comp. is around 8.0:1 so with an autom. and only 3.23 gears a bigger cam and intake probably not worth a possible slight hi rpm gain and low and mid rpm loss.
You would be amazed what a little head work will do. That's where I would go next.
Port and polish the heads, cut .040 off them and us the mopar performance thin head gaskets, worth a whole bunch of torque and pulling power. You will need 91 octane gas for the added comp.
