SBM Edelbrock/Speedmaster Head Data

Reply to Earlie-A,

Yes sandwich plates and lots of machining to both heads and LSX manifold.
Poly manifolds are rare and useless at BEST, so its time for LS stealing... :elmer:

''Why bother'' I hear you all say, we built a Gary Pavlovich 402ci Poly and have no decent intake (as yet).
The Hinkles have proved beyond a doubt that 600hp is possible with a 'boat anchor' Poly... :mob:

Why be a Lemming when you can be a Leader!:wtf:
All that is old is new again...(Johnathan Swift) cool name.
