Description

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!

Brian Tooley Racing (BTR) – the story

Brian Tooley has been in the performance racing game for nearly three decades.

Starting his own business back in 1992 called Total Engine Flow, Brian was using a Flowdata flow bench. Shifting to Holley Performance Products shortly afterwards, he helped develop the SysteMax head, intake and camshaft packages.

Going back to working on his own in 1996 until 2004, Tooley then built Total Engine Airflow into an industry titan.

Since then he sold his business to Summit Racing Equipment and stayed on until 2010 when he decided to be closer to family and friends.

As his BTR webpage revealed, it wasn’t long before Brian was back after seeing a need for quality spring kits at affordable prices.
