Trickflow twisted wedge heads

RPM427 · 05-28-2002, 10:14 PM

I just bought a 91 GT and am buying a set of twisted wedge heads, Will i have adequte valve-to-piston clearance if i run a cam with .512 of lift on it and keep the stock pistons?

Trickflow claims flycut pistons are not required if you use a street performance cam, but how much lift is that?

I am going to be running a holly systmax intake with these heads, any recomendations on a cam? I am thinking about the F303.

That F303 will fit w/o problems, its just a tick bigger than my cam. Honestly, i'd stay away from the fms cams and look towards a real cam. The holley intake is a big intake and the lower ports are matched to a 1262 gasket whereas the tfs heads are matched to a 1250 so you will have a mismatch. If your planning an off the shelf cam, i'd look towards the tfs 2 cam, comp cams xe cams or the anderson cams. Just my inexperienced $.02. My guess is if you cam the car correctly, that holley intake will work good, but if you cam poorly, it'll just be an overkill.

I am probably going to go with one of the extreme cams from comp cams. Any suggestions?

I run the e303 with 1.7s (.529 lift) no problem. 220/220 duration. Im going to the track tommorrow and will post the results.

Cant really help w/ which cam to get. I see your in Huntington, i'm in Lynbrook. Where do you hang out?

StreetStang37, I recommend 18* timing. Make a pass as is, then try 18* and you should pick up a little mph like 1-2. Also see how your car likes around 42psi fp or more. I was told this is a good setting for my car and our cars are very close. Post your times when you get back!

I am ussaully around DPA on Fridays and Saturdays, and go to the Bald Hill car show on tues.

Does anyone know of a closer track then E-town near Long Island, I think they closed Long Island drag strip off of exit 70 on the LIE.
Any ones closer?

Grn92LX · 05-29-2002, 07:04 PM

I hang out up there on Fri or Sat nights too sometimes. What does your car look like?

RPM427 · 05-29-2002, 07:35 PM

My current stang is the green one (now with Cobra R's), it has 55,000 miles on it. I just bought it. I used to take the all white GT in the background to DPA alot last summer.

Grn92LX · 05-29-2002, 08:26 PM

I've seen that car at dpa. Do you sometimes park it in the lot where wendys is? Besides mine, you never see emereld green mustangs there, so I remember the ones I see. Does that car have all that work done to it, or is it the white one w/ the work done to it?

RPM427 · 05-30-2002, 12:54 AM

I usually park by Wendys or in the lot with the other stangs. Right now the green stang has everything except the heads and cam. I am switching everything real soon. Any pics of your car?

The TFS heads are good to .540 lift with the stock pistons.

The F-cam would be fine. I would recommend the B with 1.7 rockers. Same lift as the F but a little more duration.

If you want to spend some $, you cant go wrong with a custom cam.
