yeah i say bigger springs and another thing on a FI motor (not so much with turbos) but the more you dyno it the hotter it gets and FI motors do not like heat. it should not make as much of a difference because of winter time but might be another reason you dynoed down from your first. i bet if you gave it another run it would have done the same thing again lost a little power

 

now i need to find some springs.

 

THat's some rpetty good numbers! On the back of the cam should be some numbers. If it was a GM cam it would have had a 3d bar code looking thing laser etched in, CompCams have a number with the letters HR in it. If you give them those numbers they will tell you exactly what the cam is.

If it was a 216/220, stock springs wouldn't be any good for that, trust me. LS6 springs are pushing it, but the 918's will be fine.

 

@ what rpm did you make 540 ft lbs?

 

that torque number is crazy

 

Very big numbers i like!

 

On a dynojet, the numbers would be bigger. Of course the M6 transmission doesn't hurt.

Sweet numbers.

 

I would for sure do some springs. I put in some K-Motions butt he 918's are nice as well! That suck about teh audible det! Good Luck man!

 

33XX, I left the graphs there on accident, i'm gonna try and get them to fax them to me on monday.

 

Thank you.
