1st,I CAN't run 91, 100 is the lowest I've used,and that's still backing timing out ! Compression is 11:1 ! No I can't give you all the teckno terms, butI have a reliable builder that I trust ! The Head was built by an A Body member and shipped to me, so I don't know exactly what race tricks he put into it ! I do have the original stock head that I shaved .090 off of and had the bowls blended that I was tempted to put together and try that and see how I made out ! Camshaft is 530/278 (?), I'd have to dig a bit ! CRS sucks !!!
It was not built to be timid !!
