Well its been about two weeks and everything is running smoothly. Car runs great. Idles nice good power bump Got gt40 heads and intake from a 1996 explorer Heads rebuilt, no resurfacing. professional products 70mm TB trick flow sn95 elbow fox valve covers (longer bolts required to bolt to heads) arp head bolts arp intake bolts new plugs for gt40 heads Don't worry about the hole in the middle of the intake... this gasket is fine. The gasket set is from a 95 cobra reconditioned the injectors like 2.50 each for the o rings and cap i cleaned all surfaces with a flat razor blade and acetone vacuumed out all the junk with a shop vac kept push-rods and rockers in same order as before with egg crates and a box with holes poked in it. just number everything on the box and egg crates i didn't change the cam so the same push-rods and rocker arms worked fine on a budget had to skinny wheel a 3/8 chunk of the egr off to clear fox valve covers also the trick flow elbow had this already cut off as it was used drilled hole through both and essentially moved the lower bolt up to secure them together used this next picture as a guide to plug and or connect the vac lines from the upper intake to the existing lines get some extra vac line hose in the 2 sizes and use bolts to plug the ones not needed I had to remove one of the alternator bolts and replace it with a machine screw to fit with the fox valve covers (these are the 3 bolts that actually hold the alternator case together) Final product I left the egr valve connected but ditched the smog pump and tubing associated with the smog pump. got a shorter belt from auto zone (search belt routing to find the right size) put a bolt in the line that goes from smog pump to h pipe. previous owner used high temp hose as connection from hard line under car to hard line on h pipe. that is where i put the bolt and used a clamp to hold it tight. my new TB and cold air kit just missed the oil fill tube, so i didn't have to modify that. marked dizzy before i started never rotated engine put dizzy back in the way she came out fired right up when i was done marked balancer got car up to temp pulled spout connector set timing to factory for now done runs great! That is all I can think of now, any questions let me know And thanks for all the help from you all during the swap Doug
Great Job! Once im done with my exterior and interior im gonna do a gt40 head and intake swap like this. Hows it feel after the swap and keeping the stock cam?
I dont have any proof from a dyno or drag strip times but she pulls harder sooner and stays in the power possibly a little longer same animal just meaner sounds a little meaner too. not a huge diff but if i had to guess my seat of pants says 40-60 hp ish I really need to get some gears next especially since I have 2.73's and 18in wheels ( that has got to be like a 2.55 effectively! gonna get 3.73's)
Everything looks good man! I wish I had a set of heads when I did my cobra intake and roller rocker swap! I've never done any research on it but what's the purpose of the MSD 6A box?
I was trying to get more spark When I first bought the car it had a cylinder that was fouling the plug on # 7 figured I'd upgrade ignition, coil and plug wires to get more efficient spark didn't seem to help didn't hurt though either below 3k rmp the box allows multiple spark discharge (MSD) the ford duraspark is pretty good imo the only weak link for up to 300hp is the plug wires. however when i go to a supercharger in the future I have read that a MSD 6al or above is the box to get for adjustability. the box I have was probably not needed and it was 200 bucks. Turns out the fouling was from a valve seal... When I did the gt40 swap all is well.
Oh man, you are gonna shit yourself when you finally get some gears. Imo it's the mod that makes the biggest difference. My brother bought himself a 94 with a ford racing gt40 grate engine in it but still with stock gears. He swore he could beat my car. After I drove his car I told him no focking way in hell you'll even come close. The car was a dog. After a gear swap to 3.73's the car became an animal and could beat mine in a drag race.
Money I did this swap while I was out of work. If I had swapped cams I would have had to get new spring kit push rods and might has well gotten new roller rockers that would have more than doubled my cost. oh then I might as well get a tune with all that changed... snowball downhill in just a few steps.. next thing im not at $550 for what i did.
