Maybe by mild he meant mild camshaft with good street manners?

 

We're all well aware of the dyno numbers TFS heads are putting up but the proof is at the track. Can anyone provide track times is the big question.
I had dyno numbers and poor track times with my last heads

 

I run the TFS heads and have track times but no dyno numbers. See link below.

wow nice times jnorris i am keeping the stock ci engine for a long time. i may never evan have a dffernet bottom end until i put twins on it after its paided off so im not worried about that. if slp headers arent known to make numbers which ones are? id love to get qtps but i cant afford them and there ory uless there headers work with a cheaper ory? so are the trickflows a newer head for the ls1s or just not as commonly used.

 

They are the newest LS1 style head on the block (except for maybe the Edelbrocks), and from what I have seen they are leading the pack right now. If I were going to spend that kind of money, I would be getting the T/F's.

 

The combo is mild, I wouldn't do heads and cam without full bolt ons. But there are a few things I did not do that a lot of the 500rwhp packages did. When the forged shortblock is installed I will do those changes, should put me over 500rwhp easy. I made a few changes to the tune and the textralia is broken in and my car drives like stock with only a nice lope to let you know its there. I could give it some nastier street manners and make sick power. No surging, no bucking with stock gears now and it chugs along at 1200 rpm no problemo. Most of H/C cars I have been in making the power I am are beasts.
