    I have a 1994 5.0L Mustang, and took a pair of GT40P heads off of an Explorer (can’t remember year). I know there’s several posts about correct-fitting exhaust headers, but I can’t seem to find any for sale. I’ve searched for MAC, FRPP, and Motorsport, but I couldn’t find any for sale. Will I...

    Im attempting to replace my heads' freeze plugs with brass ones. My issue is i cant seem to find brass ones exactly like the original ones. The ones I did find are the same circumference but is taller than the original when laid side by side

    I recently went to the dyno in my 1990 fox, and was a little unimpressed with the results. I thought the horsepower seemed about right, but I'm trying to figure out why it made max power at 5200 rpm. I have an Anderson n41 cam that should put the peak power higher than that. Any advice would be...

    The FRPP (Ford Motorsport) stainless steel GT40 “P” specific shorty headers are very desirable, rare, and super hard to find these days for those wanting to use the GT40P cylinder heads in their mustang. These headers are noted for their superior fitment and construction. I have a set that are...

    I am currently rebuilding my 99 explorer motor and am about to send my heads into the machine shop to get checked out. I have heard it's a good idea to get new valve springs and possibly roller rockers? What is everyones opinions on that? I am also looking for a good street/autocross CAM for...

    Looking for a more street friendly / stock converter friendly cam - bought a roller 5.0 with GT40P heads for a project and it's got a Z303 in there now and I want something small like a TFS 1, E303, etc. Needs to have a decent idle for power brakes and a slightly above stock stall converter...

    Hey guys, I'm looking for a set of headers that will fit my GT40P heads. I have a set of stock mustang headers, but I figure they won't really be worth trying to fit. I understand Ford Racing and MAC make headers specific to fit GT40Ps. I want to see if someone on the forum has a set they...

    Hey guys. I'm throwing a feeler for interest out there. I have a Explorer 5.0 complete with 30k miles. I had for a while, but never used. I bought it from a elderly neighbor of my parents who had it for years to drop in a roadster but never used it. I'm in the Los Angeles area. How much could I...

    I have a pair of GT40P cylinder heads that i pulled off 95 GT that i don't need anymore. Reason for pulling was new TFS TW'S. The car they came off ran perfect, no smoke and was never overheated. The decks look to be in good shape and there are no stripped bolt holes or any other damage. I'm not...

    Hey guys, I noticed my spark plug boot was burnt onto my turbo manifold the other day and I had a crazy misfire. I managed to get the wire off and put a 90 degree boot on it. It seemed a little better but it's still VERY CLOSE To the manifold. Pretty much touching it. Do they make shorty style...

    I finally did it! I made it out to Norwalk and ran Factory Stock. I had plans to wait until I had my dedicated 308 completed for this but I just couldn't make it happen in time and instead of waiting yet another year I just ran the stock Explorer LB you see in my sig. The guys in FS and CS are...

    I am building a spec racer 88 Mustang and it seems I should have guide plates on the stock 1.7 Cobra rockers. I need OEM ones from a post 1979 Ford vehicle of any kind per the rules. Ideas? Thanks in advance.
