I bought this mounting adaptor plate to fit up a T700r4 to my Nailhead. It was sold to me as being from one of the major trans adaptor kit manufacturers. Turns out it's not. Anyhow, on mounting it all up turns out the trans is offset to engine centre line by about an inch ( approx 6 degrees ) The torque converter snout is in perfect alignment with the crank. I have no information on the make. I have spent a lot of time thinking about why it was made like this. I reckon because this adaptor plate has all the Nailhead mounting / dowel points as well as all the T700r4 mounting / dowel points. Others on the market have to sacrifice some of these mounting points to make it all come together. Not a problem I would think. So my question is ----- will the trans perform without problems set up with this angle.
I'm not seeing in the two picture the problem you are talking about I'm not sure how you can offset the transmission and still have the converter snout perfectly centered. My guess is the starter mount may be creating the sense it's offset? As long as the converter is centered with the crank then it should be good to go. You'll need the appropriate spaces between the converter and flexplate.
It could be the angle on which I took the photos that you may not see the full effect. It would seem someone has designed this plate with the trans tilted on it's axis perfectly. It can only be to facilitate ALL of the mounts. I have the spacer, but no trans plate -- I'll have to make one.
I see what you are saying. If the back of the motor has the center top at 12, the transmission is pointing at 1, a few degrees clockwise. My gut feeling is as long as it doesn't negatively impact the fluid level, it will work just fine. Make sure the rear mount is accounted for and maybe put a washer on the driver side to compensate. You could split the difference and put washers under the passenger side motor mount as well.
My thoughts are also that if the oil pickup and fluid level isn't compromised then there should be no reason why it wouldn't work OK. I will have to fabricate a new mount anyway for my project, so that's not an issue. Muncie ?? This set came with T700 converter spacer so I doubt it.
Oh, you're saying it's rotated. Yes, as long as the fluid level is maintained properly it'll be fine. It's going to read high on the dipstick being rotated to the passengerside, so be aware of when it is reading full it's going to actually be lower than that by some amount.
That is one of the early production adapter plates. They were given up on in lou of the problems associated with them. I know one of them was running low on fluid around turns. Unfortunately to do it right you need to spend the $$$ on the proper, latest design adapter. Tom T.
OK, so I'm not real happy with the angle, even thought I was prepared to give it a go. As another member PM me and pointed out, because we drive on the left side of the road, the road angle may help in offsetting some of the problem with oil level. In the end decided I'll just have to have a go at making another. This is my progress so far. I've finished the easy bit getting all the engine bellhousing mount holes in place. Quite pleased with that. Now will concentrate on getting the transmission holes all lined up and centred.
