Brian Tooley Racing BTR-427+MAXNA 427+ Max Effort NA Camshaft For GM Gen III/Gen IV LS Engines

Introducing the new 427+MAXNA cam from BTR. This cam is not for the weak at heart. Intended for use as a MAX EFFORT NA style cam, they recommend using this in 427 and larger engines  with a high compression ratio, heavily ported cylinder heads, and an aftermarket throttle body/intake combo such as their Trinity series or CID style manifold. This camshaft @ 434″ CID and 14-1 compression ratio, AFR LS3 heads, and a CID intake with a vacuum pump on C12 fuel ran 5.50’s @ 123.5 N/A in the 1/8 mile @ 2800 pds.
