//4.500 RO7 GM CUP

DESCRIPTION:

When NASCAR approved Chevrolet’s new RO7 racing engine, MBE was one of the first shops anywhere with access to the castings to develop port profiles for the RO7 cylinder head. And MBE’s port designs for the RO7 head are so good that they have been raced by some of the top NASCAR Cup teams that normally race only their own equipment. If you are in the market for a top-flight RO7 cylinder head package, MBE is one of the only shops outside of the big NASCAR teams capable of  producing race winning R07s.

 

MBE’s version of the RO7 is fitted for 2.200 intake and 1.600 exhaust valves and has combustion chambers that can be sized from 33 to 50 cc’s. It will also accommodate pushrods up to ½ inch in diameter. The ports have been extensively worked until they can produce a class-leading 430 cfm through the intakes and 270 through the exhausts. And remember, MBE is the only induction specialist in the industry willing to guarantee its flow numbers.

 

This head design lends itself to high-rpm small blocks in no-holds-barred racing series. When paired with one of MBE’s cast intakes ported specifically to match these cylinder heads, the power is unmatched.
