I called texas speed and was recommended a torquer v2 cam. Well when i crunch the numers for compression I get 11.2:1 static compresion and 9.1:1 dynamic compression. From what I read you want to stay below 8.5:1 dynamic compression for 93 orctane.

Did I calculate it right and is the dynamic compression to high for 93 octane?

Cylinder head colume: 64.5 for 243 heads
Piston Head volume: -2cc for diamond racing 11512 dish
Gasket thickness: 0.051 for standard 6.0 head gasket
Gasket bore: 4.030
Cylinder Bore: 4.030 for engine bored .30 over
Deck Clearence: 0.006 below the deck
Stroke: 3.622
Rod Length: 6.125
Intake closing point: 61 deg for torqer v2 cam is 46 and plus 15

Not sure where your numbers are being messed up...I'm getting about 10.6-10.7:1 static, and then 8.1:1 dynamic with the Torquerv2 (I assumed 112 LSA and our standard 110 ICL because that gives the 46ºABDC IVC event you listed @.050").

 

I am getting about 8.0 DCR

edit...sorry 2 should have been positive...

Good to go now here is what I got.

 

^^You've got the right intake closing angle and all, but your numbers are off too...either you've got the pistons OUT of the hole instead of IN the hole, or something.

 

thanks a lot. i see a neg dish actually is positive and not negitive. that is the difference.
