I bought the engine trans combo as is with some specs on the cam and knowing it has 2800 stall, supposedly I was told its all blue printed but I don't know. He said it should be 9:1 compression it's a 1971 440. Also doing some research I was seeing that the 450's work better If they are double pumpers, I don't know never messed with tunnel ram set up. Also low on the funds so changing parts is not very easy option haha. I may be able to get a 4.10 for the rear if that will help the throttle responsiveness at all.

Also thanks for the responses everyone!
