BTR 427+ MAX EFFORT NA CAMSHAFT

BTR 427+ MAX EFFORT N/A CAMSHAFT

25X/27X, .646./.646., 111 LSA

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, we 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 our 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.

Due to the aggressive nature and high valve lift of this camshaft, it is recommended for DRAG RACE USE ONLY!
