    I thought i would share my progress with you all. I did a j-mod which after installing ruined the 4r70w for reasons i'm still not sure on but I will not get into. I decide to say F@*k it and install a tremec 3650. Feel free to ask any questions or suggest anything. I will also be doing some other much needed modifications and replacing things that need it. If there is anything you veterans would recommend inspecting or replacing while I have the motor out please comment. Thanks IMG_20170911_193559_469.jpg

    F%=÷! I,gotta hand it to ya. So much more than I would ever try to undertake. Look at replacing the oil filter adapter gasket, too. You did motor mounts which would be essential. I just had mine replaced -- what a difference. Other than that, I'm no way near qualified to suggest. Good luck!

      I did that gasket too. Is there a specific programmer/tuner you guys would recommend. I was gonna look into sct stuff.

      John Temple of Temple Performance, MK VIII Muscle.

      He installed my solid drive shaft, and produces the Terminator Bumper and does a whole shitload of performance upgrades, tuners being one of them. Great guy, and knows the cars inside and out.

      Mine is just a stock base. Traffic court used to have a bench with my name on it, but my hot rod days are now long gone. I do a lot of long distance driving -- just drove from New Haven, CT to Salt Lake City, so refinery, ride, and efficiency is what turns my wheels today. And after all I've invested in my MK, the drive was exceptional -- nearly 3 days -- and I loved it.

      I have been working on this for months in what little spare time I have. I just now decided to post it lol. I decided to keep the gears. I'm hoping the lower first gear in the 5 speed will pick it up enough off the line

      More progress! I got the motor put back in and started reconnecting things. Tidied up the ecm mount installed the clutch master and the stainless braided hydraulic line. Had to use the persuader to make room for the steering shaft near the headers.

      I am glad I wrapped these the tolerance is very tight to many important items. would have liked to ceramic coat them funds permitting.

      Custom clutch hydraulic line with the thunderbird oem fitting on one end and the quick connect fitting on the other for the tremec 3650 made by the local tubes and hoses shop.

      Used some dent protector door edge molding to shore up some of the extra space in the bracket caused by leaving the retainer out which was not allowing interior panel to go back on under the steering column.
      20171113_165521.jpg
      This piece and the clutch bracket where alot of trial and error getting them to fit right in the car and would probably be different for each intallation. lots of room for improvement on design but its sturdy and snug.

      Barton short throw shifter. Got lucky and found the linkage between shifter and trans on ebay aswell!
      20171113_182801.jpg
      Here is the clearance issue between the steering rod and header. It had only mm to spare but was not touching. I beat about a 1.5" long dent in it. I was able to pound out about and extra 3/8 of an inch with it in the car but definatly would be easier outside of the car. I hope that is enough.

      This measurement is from the collector to the steering rod if you are going to install these headers on a 97-98 Mark. The primary that needs persuading is the lowest most primary on the engine side of the driver side Header. In other words the #7 cylinder primary tube.

      What kind of a gear box did you do ? Very impressed with the workmanship. What kind of a shifter is it? Looks like its for automatics

      Fantastic! Great creativity using the door edge molding to assist with the bracket!
      Make sure you use a dial on the transmission bellhousing to ensure you have the transmission and engine lined up. If they are off you will have issues. I swapped a T56 in to My Trans Am (I bought it for my winter ride) and a dial wasn't used and it smoked the pilot bearing. My mechanic said it was my parts, replaced bearing and less than 100 miles later same thing, but this time damaged input shaft. There is lots on line. This should start you off:

      “Engine block, bellhousing, flywheel, clutch and transmission input shaft must all be in perfect alignment for optimum performance,” Couture tells us. To ensure everything lines up, he suggests beginning your fact-finding mission with a dial indicator, which can be found at most auto parts/supply stores, including Harbor Freight. Dial indicators are reasonably priced and are a must for every toolbox.
