//SB2.2 DRAG SPECIAL GM

   RAISED PORT

DESCRIPTION:

MBE’s SB2.2 Special cylinder head is practically a clean-sheet design based on the Chevrolet’s SB2.2 architecture. Beginning with their own casting, MBE Cylinder Heads and Manifolds has created what can only be called “an SB2 on steroids.”

 

By raising both the intake and exhaust port runners a quarter of an inch and precisely controlling the cross-sectional area along the entire length of the ports, MBE has created an SB2 head with record-breaking flow numbers. We’re talking 450 cfm for the intakes and 292 for the exhausts—and remember, MBE is the only cylinder head specialist that guarantees its published port flow numbers.

 

Big flow requires big valves, and that’s certainly the case here. Each head is outfitted with big 2.250 inch diameter intakes and 1.575 exhaust valves. The chambers can be sized from 33 to 55 cc’s, and when combined with MBE’s custom ported cast manifolds, this combination will make more power than any other SB2 in a single-carb application. This is an excellent competition head for serious drag racers in the Comp Eliminator or similar classes
