SBM Edelbrock/Speedmaster Head Data
Always had a fascination for Ovalport heads myself.
Mother Mopar did try them in and around 1970 with an Ovalport 440 pass. car head.
Got a pair here in England that were done by Weslake Engineering, also in Kent.
Reportedly capable of 600hp for NASACAR after the Hemi ban in 1971.
D-port exhausts and 2'' inch tall intake runners.
Ran them on a street engine back in the 80's they was wicked.
The Big-block porting plate is overlaid on a W2 gasket to show the difference in size.
It was stamped 'W2' but I think they are really 'W1' heads.
