trick flow 215 heads
Will these heads flow increase beyond .600 lift? They are recommending roller rockers with these heads. The cam I have selected has a.585 lift on both valves.

I would say yes, but not by much. But I can't find a flow chart for them that goes over .600

trick flow 215 heads
what hp do yall think the motor once properly tuned will put out? Fast 92mm intake and throttle body,compcams 232/236 and 585 lift lsa112 stock bottom end with heads milled to creat 11.1 comp ratio. Haven`t selected the injectors yet. Any suggestions? Will have custom headers made, but not sure what lenght to run.

I was told that I would be putting out 515hp at the crank. That was before the fast intake. According to TEA.

If your not going to run NOS, turbo, or supercharge it you should run the other head they have. They just came out with it in march and they help keep stock compression with out having to mill them. You could just change pistons to a +cc and get in to the 11 range. Here is the info. http://www.trickflow.com/pressreleases/GenXStreetHeads/
Call thier tech department and talk to them. I called them and he said the new LT1 and lsx heads are better matched for NA engines. He said this head was designed for the truck motors and LS1's not realy ment for ls2,3..Last edited by JaycenK; 06-19-2009 at 03:46 PM.

I orderd these heads a few days ago and these are the ones that TEA suggested. Unless you are running a strip car, these are pretty good heads.

Ok, now i am wondering with the same heads a little larger cam and stroked out to a 383. What do yall think that will give me at the crank and at the wheels? Still running the 4l60e. I ahve a stall out of a 700r4. If it won`t work in the 4l60, what should I replace it with?
