Basic 318 Mods

Dan the man said
Wish me luck as I'm going to be checking out a couple of duster's next week. I'm only asking these questions as a quide, both are 318 cars but one is a 2 barrel. Once the car is home I'm going to check it out completely and if everything checks out okay I'd like to do a 4 barrel swap and was wondering what size carb and intake manifold to use. I thought about a better coil and module. A curve kit and a good dual exhaust system. The car will be a cruiser only and probably the engine will never see more than 4500 rpm's. I'm open to a stall converter and a different gear ratio. Maybe even a mild cam.

Best of luck.

I'm buying one. Just because it won't see high rpm's doesn't mean that I shouldn't do some things to it. I'm sure that 318willrun will chime in. A mild stall converter and different gears is pretty much the popular mods to do

Don’t worry about gears and a converter yet.
If your cam and gears don’t match, your going to need a converter or if the cam is big, a converter is needed.

As YOU described the car, not over 4500 rpm, I’d leave gear and converters alone. The unit upgrades I’d entertain and have done as a basic hop up and are a suggestion for you are;

Carb - 600 AVS-II & a Performer intake.
(I use a Lokar set up for the trans kick down and throttle cable. Quicker and easier than locating a factory set up.)
Chrome ignition box or equal.
Dual exhaust @ 2-1/4 inch

There's really no downside to a 4bbl it's 2bbl 99% of the time until you need that extra bit of power for passing/merging/fun.

Bingo!
