I could use some help with a new engine that I recently bought from another member here. It's a 73' 20 over 400. Stock crank and rods, balanced and assembled. It has stock 87cc edelbrock heads/arp bolts. Installed is a comp 280ah-10 flat tappet hyd.The motor is fully assembled and complete ready to install. I am putting it in a 69 gto conv.It has 3.55 gears, th400/2200 stall, and I plan on using my rpm intake and holly street avenger 770 carb. Of course I just recently bought d port headers,figures.My main concern is the cam, which is comps RA IV. I don't take the car to the track, or race it. But I do drive it HARD. I currently have the Crower 60916 cam in the original engine,with rpm and holly on top,acell electronic dist and headers into 2 1/2 exhaust.I like the "personality" of the engine as it is but would like more "freight train" since I now have the e-heads. I would consider the crower cam pretty tame but decent.
So basically what I am asking is what would be a better choice of cam for this combo, than the comp cam already installed.I was originally going to just throw it in and run what was in it , just to see. But I don't think I have enough stall, or gears, and I would prefer a broad flat torque curve as opposed to a high rpm race engine. I don't want to go too big and lose my lower rpm power, and I'm afraid of leaving too much on the table and not using the potential of the heads.
Also what headers, or RA manifolds would be best. I have only been able to find 2 headers for round port . Dougs, and Hooker super comps. Is that all there is ?
Oh the pistons are flat tops, forged. I was told this motor was built to be about 9-9.5 to 1 compression.
Her is a link to the ad from which I bought the motor. Paul the seller is a great guy and was very helpful when I went to pick up the engine.
