HOT CAM DYNO SHEET.. SAME DYNO SAME TUNER

 

Holyy ****. crap. That's incredible.

 

Good numbers! Are you happy with it?

 

I am.. he is happy as well..

This cam works very well with these 5.3's..

Thunder Racing has done their homework..

 

wow those are awesome numbers! must have a good tuner...

 

Thank you.... yes Owen at ARD is very good with these trucks (cars)...

 

Pretty much seals the deal for me, that will be my cam.

Nice numbers, do you have any track times?

 

Are the rocker arms, push rods, and springs stock?

 

im sure the push rods are hardened and the valve springs are definately not stock with that cam....im runnin the TR220 with the 918's and 7.4 comp rods

 

very nice #'s!
looks similar to mine except i put down 340/340 SAE

this just goes to show everyone that it doesn't take a big cam to make good power. the good thing about this is you have excellent torque down low and it can still pull up top too. funny thing is these lobes are well over i'd say at the least 7 years old. i'll also go ahead and say it is probably the best off the shelf cam for the 5.3.
