Re: 1966 L72 Impala In UK
An interesting thing about the engine being dyno'ed:
"... it cranked 438 HP (with headers and no air cleaner), With a dual snorkel air cleaner, it cranked 429 HP, so pretty close to 425. That’s with all NOS internals (cam, rods, crank, lifters, etc.) except pistons, which are .010 over."
