Re: best cam for L/SA 89 Mustang
thanks. i'll get a measurement on PTD and then decide what to do. luckily all I have done so far is drop in the crank and I piston to measure PTV and degree the cam.

has since rescinded that rule. You just can't be above more than the given spec. I would check with Glendora to be on the safe side though. |

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! |

Just get some Cometic gaskets in the thickness and bore size you need. Leave the block alone.

Re: best cam for L/SA 89 Mustang
Mark,
I hate to say no, but I was doing a BB Chevy combo that has an AB demension and was told it needed to be above the deck. I think that is something that needs to be addressed and put in print. This was less than a year ago. So it might be different in Div. 4. I'm now doing a Drag Pack that calls for AB. I think I will hold up. What do any of you guys running Chevy LS say??. They call for AB in the specs, too. Hummm
