The stats I have read on the new Gm LM1 crate motor states 250 hp. Is this with headers and a four barrel? TPI with headers? Stock manifolds? Please advise.

It is with stock manifolds, an edelbrock intake, and a 650cfm carb.

So you must be up around 275 hp with your setup?

yeah. with the horsepower calculator it was about 280.
