trick flow 215 heads

[scubamark3995]

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

your dealing with one of the best heads on the market...those heads will meet almost all your needs you would ever push to them.

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'll say well over 400+ rwhp, maybe 440.
what for a tranny are you running?

[scubamark3995]

I am running a4l60E. I Probably just lost a hundred horses on the estimates.lol

[scubamark3995]

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..

[scubamark3995]

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.

yup your looking at about 440 rwhp with the a4.....that thing is going to be a beast
what car are you droping it into, the 78?
also you are running a stall and tranny cooler I hope

[scubamark3995]

Yep a 1978 280z. with a zz4, 195 afr`s, 236/242 520/540 lsa 112 ,rpm man,750 holley, 700r4, 3200 stall and 3.90 gears and a suffacating single exhaust w/shorty headers. I twas turning 11.50`s w/1.68 60' times at 117 mph. I am praying to heaven that it will be solidly in the tens.

[Sommer86@6LE]

would you choose genx street heads over AFR 205's?

[scubamark3995]

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?

nope your stall won't work.......id look for around a 3,600 rpm stall.
you need to get one specificly for the ls1 and the 4l60

[garygnu65]

42# injector should do.

[scubamark3995]

42# injector should do.

The ford green top ev1? Or if it is the ford green top it will work? Much cheaper than the fast.
