Dang Kirby! If you’re just tossing out invitations, I’m on the East side of Orlando near UCF. If you’re gonna be in the shop on Tuesday, I’d love the opportunity to swing by and pick your brain on some possible engine upgrades.

 

 

actully ment MERRY CHRISMAS to you too,but your more than welcome to stop by tuesday

 

As djl and kirby stated, Get them cc'd have heard them get to 89 cc as well... 4 cc can make a lot of difference when it comes to cam selection... A cam that performs very well at 10:1 static compression will not perform as well at 9.6:1. 4 cc can make that much difference cause now your looking at a ccp difference of 10 psi. Take the Andrews 57 cam for example @10.06:1 static your dynamic comp would be 9.35:1 w/194 psi ccp. @ 9.69:1 with an 89 cc chamber your dynamic comp would be 9.0:1 w/185 psi ccp which will make the Andrews 57 cam soft on bottom....

Mind you these calculations were done @sea level..

 

Cleaned, prepped, and cc'd then you'll know, if staying with the untouched cylinder head.
