Introducing the new 427+MAXNA cam from BTR. This camshaft 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 the Trinity series or CID style manifold. This camshaft in a 434" engine with 14-1 compression ratio, AFR LS3 heads, and a CID intake on C12 fuel ran 5.50's @ 123.5 N/A in the 1/8 mile @ 2800lbs.
Due to the aggressive nature and high valve lift of this camshaft, it is recommended for DRAG RACE USE ONLY!
