I am also running a Holley terminator x with a 1300 cfm throttle body
The engine was Dynoed with only a 750cfm carb as they didn’t have the setup to run efi on the Dyno and it made 551 hp and 555 torque at 6500 rpm
When I bought my combo from butler the parts combo was put together with the goal of 650hp so I was about 100hp shy of that
My questions is how close will I get to that with my 1300 cfm throttle body compared to the obviously to small 750 carb?
The goal with the Dyno was only to break the engine in properly before I put it in the car which I accomplished and everything ran great! I just wanted to get your thoughts on how much HP and torque I lost with the engine being under carbed compared to what my goal is.
Thanks as always

Watch this video, give you a good idea on what you could pick up with Throttle body. Forget it’s a Chevy tho…LOL
