Cheap Power!

RPM427 · 02-26-2002, 01:09 AM

I am going to buy a set of GT-40 aluminum heads and a f-cam, Will the piston-to-valve clearence be adequete on a 91 GT?
I am also using a holley sytemax intake, Any Horse power estimates??

your fine on clearance HP guess.. 310-320 FWHP roughly.. forget the F303 and get the Lunati 1087 you will be happier in performance and sound

The F - cam is better suited to blower applications. Are you planning to put a blower on at a later date? Your piston to valve clearance should be fine but it doesn't hurt to check it. As for HP, I would think 300 +.
I noticed your sig says you already have AFR's, why are you switching to GT - 40's?

I have AFR's on my 89, I just bought a 91 GT and that is the one i'm putting the GT-40 heads on. They are the GT-40X performance "turbo swirl" aluminum ones. I should make more then 310 hp right?
I am planing to put a s-trim on it in the future, and whats the profile of the lunati cam?

I also have underdrive pulleys, a holley systemax intake, roller rockers, and MAC full length headers. Is the 310HP estimate still accurate?

TFS Stage 1 would work nice. I've got an F cam in my car right now and gonna switch it to the stage 1, can't beat the price, that's for sure. The F cam is a good blower cam, and has worked well for my N/A and nitrous runs, but I'll admit I'm anxious to see what the TFS cam is like.

What are the specs on the Lunati 1087 cam? I have the 51014 Lunati cam and love it. I just can't seem to find the specs on the 1087 though.

285/291 @.050 its 221/232 .526/.530 Lobe Sep. 111

thats the NEW 1087 from Lunati since Wolverine Blue Racer discontinued it.. Holcomb Motorsports sells the new peice they say, " New design 1087 camshaft Designed for EFI cars Lunati took the old 1087 cam, upgraded it with 21 century technology.. Possibly the BEST performing cam available for your Mustang" thats what THEY SAY i think the old 1087 had better specs.. 288/299 .510/534
