Big Block Advice Needed

It’s pretty hard to make any power from a combo that only has 125-130 cranking pressure.
One or more of these scenarios is probably in play-
-CR is less that 9:1
-cam is rather large
-cam is installed retarded

Imo, a head needs to come off and things measured to determine true CR.
Cam specs need to be verified..... by measuring or by part number.

Imo, the TR/1050 won’t help with your goals.
