Test fit in my car. notice how the lower control arm sets into the frame rail, giving more space between the frame rails. The crossmember is beefy, it should hold up to whatever torsional braking loads I can throw at it. I like this design, Martin did his homework.

Not a bad idea to check your bellhousing runout, but with a T56 bellhousing, unlike most transmissions there is no suitable place to check runout. You can bolt the transmissions front cover onto the bellhousung and check it on the bearing race.

I had this t56 from a lt1 car and decided to swap it over to a LS style and use it for this project. I needed to swap the front cover, input shaft, press bearing, re-shim, etc. This was my first time into a manual transmission, great learning experience. Fortunately, everything inside looked good.

So i decided to try to run v8r headers with the monster subframe but had a little interferance in a couple of spots. I made up these plates to move the motor back an inch to fix the clearance. 3/4" would have been better. I had to clearance to top of the tunnel with the additional setback. On the plus side, since i'm running f-body accessories, the extra inch up front means i wont have to comprimise on my fans/radiator placement.

I had a "viper spec" LT1 t56 and decided to run it instead of the t5. I needed to convert the t56 to an ls1 style which involved replacing the input shaft and transmissions front cover/bearing retainer... Tremmic calls it a "mid plate" There is no center register in the t56 bellhousing so to check runout, you have to bolt the mid plate to the bell. And check it on the bearing race.

Replacing the mid plate and input shaft means the transmission needs to be almost fully torn down to re-shim it properly. This was my first trans rebuild... Althought with only 5k miles on it, nothing needed to be replaced.

I built a trans mount... Its very simple but was a bit of a pain to get the angles just right. I tied it into reinforced area where the seats mount. Its very solid. I may also hang the exhaust here.

Got my radiator mounted. I ordered a basic dual pass and fabbed my own mounts. The lower isolators are from a 2002 dodge 1500 upper radiator mount

I'm moving the radiator forward an inch and using the miata isolators for the upper mounts through the core support.

Radiator all mounted up. I ordered a dual pass the right dimensions and fabbed my own mounts. The lower mount is an upper mount from a 2002 dodge 1500

I moved it forward an inch. There is still room for a condensor in front. The original upper mounts were cut down and welded to the core support.

Typical Corner mods. In retrospect, I'll try to leave whatever material that I can in the corners next time. It would be useful to have a template from a car with the motor already installed to see what actually "needs" to be cut.

I also ended up clearancing the top of the tunnel because I moved the motor back 1". I didn't need to cut it to fit it in Martins intended position. I know some people cut and notch here but I just worked it slowly with a hammer. It came out pretty good. I'll try to get more pictures of the tunnel mods the next time the motor is out, but they are the typical mods everyone does.
