Bottom End Shocker Build

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.
5/16 stock fuel line and tank
