390 build questions
I acquired a 390 don't know what year, I will get numbers off block when I get the motor. I want to put it in a early 80's f100 or f150. I want to paint it primer red with a semi gloss clear coat and stock white wheels but want to widen the rears to put something like the old m50 15's on it. I want to build the motor to where its around 375 to 400hp. I don't want a solid cam and I don't want to have to use a stall spd convertor but if I have too not a very high stall. Maybe a small shot of nitrous if it will me help reach my goal. I want to stay away from adjustable rockers if possible. I am wanting to use a 650 or 750 dual pumper carb,headers,c6 tranny,and 355 to 410 gears in the rear end. I've built a couple small blk mopars, this is my 1st ford build. I need recommendations on cams,lifters,intake,ignition,and head work/valve work. I want it to turn heads when people hear it . So help me out please.

First off, those M50 tires, what are they, 40 years old?
A 390 can make that kind of power with mostly stock heads, valves, lifters etc.
Your power upgrades on a 390 are first in getting decent compression. 9.5 or 10ish can run pump gas, and stock pistons (car 390 or pickup 360) will work.
Exhaust: Stock manifolds are power killers, look into quality headers like Sanderson.
Cam: "lumpy" is where you are going.
Other details can be found at this thread, with multiple links, especially in post 7:

The FE motor has seen increased interest in the last few years. Note that CarCraft link goes 446 stroker. The upgrades shown to that engine can apply to a 390. You will not be a 500/500 but it will be quite a bit cheaper.
