Very true! Stock heads only flow so much.

 

that is definately a donkey dick cam in a stock 5.3

actually a few degrees bigger duration than i am running in a 370 with cnc heads.

i would love to see that graph. start pulling around 4500 or so?

very good numbers none the less. around the same as a H/C 5.3 should be

 

well thanks for the compliments guys... Yes the cam is big, but heads and a 3500 stall is coming next. What can you say when you get a free cam install is and make those kinda numbers... sounds pretty good to me. Should make some nice numbers once the heads go on.

 

probably make about 500 rwhp with the heads on the same dyno?

 

I bet that thing has no power under the curve though. It already sounds like a dyno queen to me.

Post up the dyno graph!

alright well heres the graph...



We are hoping easily for 500whp once the heads go on.

 

LOL i was joking about 500 rwhp

a 5.3 H/C has never seen over 400 rwhp, as far as i remember, with stock truck intake and no nitrous

 

figured you were... but i think if we cant get that it should be close.

 

so you plan on gaining 140 rwhp with heads?

good luck
