So I have a stock 1980 360 with 15000 miles on it. Came with a 1406 efelbrock on top a cast iron manifold. Ran a compression test and have above 110 psi on each hole. Assuming it's still stick with what 8:1 compression and small cam. I'm looking at dropping her in my pick up to get some track time next year. I want to leave the bottom end alone but will be inspecting bearings and resealing it. Also gonna change the cam and mild head work. I'm thinking I want to run around a comp extreme energy 284 I believe it is, going to have a 3k stall converter and still looking into gears right now. Have on hand 3.55 and 3.23s. I know I'm gonna have to replace valve springs, gonna replace timing chain with a quality one. Want to shave heads down and run headers. Any other suggestions? Guesses on how it'll run with the lack of bottom end?

Ps I'm not planning on using this for a tow machine or daily driver just some good summer time fun
