Default Re: best cam for L/SA 89 Mustang

WTF ?/ (What the Ford?) Bounced for below the deck? Really?

Sounds like you had some real lulus of tech guys back east. I had my motor teched in Div 6 when I set the P/SA record, the only thing that mattered was total deck + gasket thickness as allowed in the rule book. The tech guys were professional and measured everything but went by the letter of the book/ cc'd ports. pull valves/ cam check/ piston deck check/ all very through. I was impressed.

If you set a 5.0 at .0135 AB+.041 gasket =.0275 piston/head clearance. Good luck there, maybe you run yours that tight, but mine get shiny at .035. NHRA posted deck clearance specs are MINIMUM deck specs and I would expect anything below that would be ok. They come factory way below the deck!
