    4.6 3V engine rebuild plan version 28

    I already had a thread going on this, and I didn't see how the cancel this one. https://www.s197forum.com/threads/has-anybody-done-this-machine-shop-rebuild-and-thro-in-a-comp-cams-127200-and-mahle-10-9-1-pistons-on-a-5-speed-and-4-10s.153210/#post-2581057

    4.6 3V engine rebuild plan version 28

    This is my current plan after bouncing around several times. Around December, Kelly Machine in Phoenix will re-build my engine using my Comp Cams 127200;s, high volume Melling oil pump, and my Ford brand cam phasers and VVT's. Everything else will be new provided by him; w/ +.020 stock...

    To rebuild a 4.6 3V, or buy an 07-09 GT500. I really want a GT500; I hope it's a good idea. LMK!

    I test drove a beautiful 2007 GT500; it had an aftermarket pully and CAI, should have been around 600hp. I sooooo wanted to love the car, but didn't. I did not feel the hard accelerations in the low end, I did not feel the 'always-on' torque. I loved the idea of the car, but for power I like...

    Has anybody done this? Machine shop rebuild and thro in a Comp Cams 127200 and Mahle 10.9:1 pistons (on a 5 speed and 4:10's).

    Just remembered. I did talk to Lito about it, and he was concerned about anything over 11:1.

    I will research that, I need to know. The tuner said he would take the timing back to a safe position for pump gas, and I don't know how much HP loss that equates to.

    Has anybody done this? Machine shop rebuild and thro in a Comp Cams 127200 and Mahle 10.9:1 pistons (on a 5 speed and 4:10's).

    Good thought. I just talked to Mahle tech and these will work with stock everything He ball-parked a calced guestimation of 10.6 hp gain from the compression alone. These engines are high-dollar per horsepower with diminishing returns. It should be ok, my carboned-up '08 engine (in an '05)...

    I don't have a good answer for that. The rods are the same dimensionally as stock, not sure piston height difference, and +.020" might make it a 283'ish if everything was equal. The 420hp seemed do'able from the bench racing I have seen.

    Has anybody done this? Machine shop rebuild and thro in a Comp Cams 127200 and Mahle 10.9:1 pistons (on a 5 speed and 4:10's).

    I want to keep the budget on the low, so I would like to hear from somebody that has done this 'set-up' and what the results where. I will use Kelly's Machine Shop in Phoenix to rebuild my 4.6 3V (they know the ins and outs of this engine), and BTW thro in my Comp Cams 127200's, my Mahle 10.9:1...

    That's what I wanted to hear. It's time to pull the trigger. Thanks for the info my friend.

    Thanks, Dino. I very sure it will make me happy. Do these cars launch hard with the 3.31 gears; or are people changing them out. My 2005 GT has 4:10's to axle swap, that may be too low (just like it is in my 2005 Mustang).

    I have a 2005 GT vert that I love. All the bolt on's, Long tubes, Exedy stage 1 clutch, 4:10;s. I have 10.9:1 pistons, and 127200 cams for the build. But I know think I want an 07-09 GT500. I need some advice on this; is it a good idea. Thanks, Jerry

    Who still sells 11:1 pistons for the 4.6L 3V. The best I can find is 10.36:1.

    Ok, I'm interested. Do these pistons have valve reliefs, and they don't need something odd like phaser limiters, right.

    Mahle has not made those for many years. Is the kit new or used?

    What is the piston part number. I am not really sure I can get away with .020"; long story.

    Who still sells 11:1 pistons for the 4.6L 3V. The best I can find is 10.36:1.

    I talked to JE and the 314604 +.020 pistons above, can be made as +.030 for a measly $40 for the set. So either way, this forum has been major score for me not settling for the 10.34 CR DSS pistons. Thank you Dino.

    Who still sells 11:1 pistons for the 4.6L 3V. The best I can find is 10.36:1.

    Thanks Dino, I do appreciate it. I was so focused on the .030" over I assumed the .020" overs could not make it happen either; hopefully .020" cleans up the cylinder walls. Also, I thought .030" overbore was the max for these engines, how do we get to 3.633 and 3.701 bores on some of these...

    Who still sells 11:1 pistons for the 4.6L 3V. The best I can find is 10.36:1.

    I should have added that I looked at Wiseco, Manely, Diamond, TSP, KB, Mahle, Silvolite, JE, ModMax, Livernoise, and the winner so far is DSS with 10.363:1. I have found a couple of Manley pistons that look promising but are vague/mis-labeled, and end up being for the 2 and 4V engines after...

    Who still sells 11:1 pistons for the 4.6L 3V. The best I can find is 10.36:1.

    The only pistons I can find are for he 5.4L 3V, and the 4.6L 2 and 4 valve. Anybody know which .030 over piston can do 11:1?

    Connecting rods that are 5.933 stock, and 5.950 stroker rods.

    I need to order connecting rods and pistons other than stock. I am not finding much info on this; can anybody give me the low down. I see connecting rods that are 5.933 stock, and 5.950 stroker rods. Can these rods be used with a stock crank, and stock configuration piston? And what do you...

    Installed Accel SuperCoil on car, now it barely runs, even with the original coils on the car.

    So the answer appears to be pure coincidence. The attached pic is my Amsoil filter with the special metal flake.

    Did you notice any improvements on the butt dyno?

    Installed Accel SuperCoil on car, now it barely runs, even with the original coils on the car.

    Thanks for the info. I purchased a tester to go between the coil pack and the spark plug to know for sure if the coil is firing; rented a light flasher to plug into the injector power plug to make sure that is firing, and I'm doing a compression; its running so badly, I need to confirm I still...

    Installed Accel SuperCoil on car, now it barely runs, even with the original coils on the car.

    I have a 2008 GT that ran great. I replaced 1 coil pack (#1 cylinder) with an Accel SuperCoil for a test fit. I drove about a block and the car starting running terrible. I came right back home and put the old coil back on, but the car still idles like crap. My OBDII tool says mis-fire on all...

    Need help choosing between Comp cams 127200 and Detroit Rockers.

    A word from Lito: Hi Jerry, the 200s (and the 300s but this require springs, etc.) will have better performance than any of the cosmetics (Hot Rods, Detroit's, Rattlers, Thumprs...) Every cam would usually move the powerband up in the RPM range, that is how make gains but the cosmetics tend...

    Need help choosing between Comp cams 127200 and Detroit Rockers.

    Detroit Rocker Naturally VS Comp Cam 127200. Anybody have some good info when I comes to pick one of the two. I have a JLT cold air intake, JBA long tubes, catless, Exedy Stage 1 clutch, 4:10 gears. I want the most power and torque, sound is not as important, I don't want to change springs...
