Hey whatsup guys. So i have a quick question for those who know anyone in the area of miami that ports heads but is actually good. Im buying this engine with gt40 heads and intake and the car has a "mild cam" thats what the guy told me. since my car is still running, i was planning on porting the heads and the intake to match, find out what cam it has a from there determine what roller rockers to run with the heads. And just put everything new on the engine and drop it in my car. So my question is, Do any of you know anybody or any shop that is recommendable for porting? And in your guys opinion, What cam should i run with these heads if they are going to be ported. I hear alot of people running B303's but i also hear they make more noise than hp. so feel free to give me your opinion on what you guys think, im open to anything. I do know that i DONT want to run the E303's, my friend did the gt40 set up with that cam and my car was stock and i smoked him. (mind you, he hadnt replaced his fuel pump with a bigger one for the 24lb injectors)

Oh by the way, i have a 91 lx and the engine im getting is a 90 5.0 from a lx convertible.

so you think a b-303 will do any better than a e-303?? to many variable guess why you beat your friend, but don't expect much from gt-40's and letter cams. I have seen gt-40 equipped cars run well but then again the heads have been worked to the max and the proper valvetrain components were used as well as complementing supporting mods, such as a decent cam, intake , ect, ect............

Ported GT40P heads will make good power for the price, but I would go with an aftermarket intake and some upgraded valve springs, they were kind of weak. Letter cams are just overpriced imo, trickflow makes a good product, start looking at them for something. J

Ok, So the exact set up im planning for this engine would be,

Ported GT40's
TFS 1 Cam Or if the cam the engine has is good, ill keep that one.

Specs for cam link^
Harland Sharp 1.7 Roller Rockers
Trickflow Pushrods 6.700 in. length
Comp Cam Valve Springs http://www.summitracing.com/parts/CCA-986-16/
24lb injectors
BBK Fuel Rail
Ported Gt40 upper and lower to match heads.
BBK 65mm TB
BBK CAI
BBK Underdrive pulleys
BBK Longtube Headers

What So do you guys think?

And another quick question, the engine i have in my car now has stopped receiving fuel to cylinders 1-2-3-4. (well i assume its fuel) But when i turn on the car it backfires hard and shakes alot, and i could pull all 4 plugs and the car has no reaction, i pulled the plug out on spark plug(cylinder #4) and turned on the car, and saw its receiving spark. The only thing i did earlier was remove the valve cover which had made me remove the throttle body and spacer. when i put it back i turned on the car with out plugging the IAC and quickly plugged it back in, and the car is still acting the same. I reset the computer by disconnecting the positve from the battery and sparking it a couple times. Any Ideas? Thanks in advance

I doubt 6.700 push rods are the correct length, they are more so used with tfs heads, you need to measure for correct length, no guessing!!!

Danielsmustang

How do i find out whats the correct length? And By the way, the whole problem was just that i didnt check after my friend and he has put the wires all messed up. Fixed it up a couple minutes ago.

you buy an adjustable push rod
