need some opinions on carb size. I have a 1250 APD alcohol Domi for my combo.

545 ci
P51 out of the box
MSD ignition
roller rockers
flat top Probe pistons
Cam specs are solid roller, gross lift .757 .751 e
duration 306/322E @ .020 A Kaase grind 110 lobe center

is the 1250 too big or not big enough?

any guesses on horse power?

If the carb was set up for that type combo it will be fine.

1250 is big for an alky carb but I bet the boosters have some big ole skirts..............
