I got my motor today chevy 350 and I am lookinng for ideas on intake manifold carb and cams what are some good ideas I want some advice on them I'm looking to add some nice power to it but not suffer more on gas then I already will and some ballparks on how much ill spend I want to put around 1500 into it thanks for the help I really appreciate it

 

Unless you are going to be racing it, I would go with a good dual plane intake manifold, 650 cfm carb with vaccum secondaries, headers and a mild cam.

+ 1 ^^ And you'll have some change for an ignition.

 

I'd second that! If keeping gas mileage is a concern, then you don't want more than a mild cam. Don't get wild on duration or you'll end up using lots more gas. I'd stay in the 250-268 degree duration, and not more than around 450 lift.

 

Yeah that's like exactly what I was thinking guess I'll go with that haha I just wanted a good second opinion I was also wondering if like year one or any place sold like full kits like wiring harness water pump fuel pump altinator cuz when I bought the motor its just the motor none of the other stuff thanks a lot

I'd agree with that mostly,you didn't say if you have a stick or auto trans.
With a stick I'd rather have a Holley 650 spread bore manual secondary double pumper but that's just me.
Gas mileage will be determined by your right foot.

 

You shouldn't need a wiring harness for those items, if you already have a car. The wiring for those items isn't part of an engine, it's part of the body wiring. I doubt you have an electric fuel pump or water pump too.
If the engine needs a water pump then buy one. If it needs a fuel pump you'll want a mechanical that bolts on the engine on the pass. front side. Might check there to see if it's already there. Get an alternator once you see what plug you have on your harness. Can't say if it's a 1 wire or 2 wire myself, as I'm not sure in '81; might even be a 3 wire???
