136 hp from headers, carb, intake, and a cam change does not seem like too big of a stretch to me on a BBC. Are you of the opinion, @PRH that the engine here could see 100hp with an intake and carb change? I personally don’t see 100hp coming.
Not at all.
As I said, that bbc build had what I considered to be a big problem with the combo if you’re trying to make hp......the SP2P intake.
On paper, I really don’t see any red flags with the OP’s combo.
Not any that are of the 75-100hp variety.
If I had it on the dyno here, my “expectation” would be that the numbers would be around 500tq and over 400hp.
“Assuming” the flow numbers are close, and that the overall head prep is decent.
That being said.......”if” the numbers here were a repeat of what he’s seeing now....... it would be an interesting project to figure out exactly what the cork is.
