Ok finally got back to the dyno. Same combination execept Harlond Sharp rockers......
657.5 hp @ 6100
638.6 tq @ 4800
on Sunoco 93!!
Video of pull Tried a M1 with 1" spacer on it also....
ran 1 hp under the sd. The sd had a more straight curve to it. the m1 was very choppy. Sorry can't find the sheet right now for the M1 so no exact numbers.
All in all made 16 pulls yesterday. Only "scare" was losing 50hp on the first run with the M1. found a piece of bowl gasket in the front jet. No harm no foul!!
Very Happy!!!
