the guys who did the 477 horse 318 for Enginemasters didnt think so.
They ran the crosswinds air gap knockoff on it. Made that power at just over 10 to 1 compression with a 247@50 solid cam.
I ran that motor( with a good bit smaller cam) in a Duster i had. Mid 11’s at 3400 pounds, flat hood, stock fan and WP.
