Hey all,
New to the forum. I figured I’d jump in and see if anyone had any advice on my build.

75 TA, 400 paired with 350 turbo. Not sure on the rear end. I checked out the stamping and it’s a late model build with the thin casting. So keeping the stock crank.

Here’s what I got. Speedmaster RAM AIR IV heads. Set up for hydronic rollers. Torker II manifold. Holly 750.

I don’t have the internal components. I’m looking for somewhere between 400-450 HP. Torque, not sure.

I was thinking about going with butlers Ram Air IV cam series. 067 or 068. Wasn’t sure on the best roller lifters. Any thoughts on this?

I was going to get new push rods. Since I’m not changing the crank just stock. Any recommendations?

Also need new forged pistons and rods. Any recommendations on those? I will say I have pulled off the heads to see what’s been done to the motor. So not sure what I’m going to find.

Any other thoughts on the right round port headers?
