building a motor plate

[XFlow_Fairlane]

I have been thinking of making a motor plate to run a SBF trans on a small bell 200. could I just do this....


get a hunk of plate (1/8" steel enough?)

drill a hole for my crank centerline and ream it out to a set size like 1/2"

insert a dowel in the pilot bearing hole to center the plate on the back of a motor and drill the two side holes and the dowelpin holes.

then transfer to the 200 trans to get the two upper holes located correctly.

follow the same procedure for the SBF trans and block to get the plate drilled with all patterns.


all holes would be transferred using transfer punches.


now I know I will need a new flywheel/starter combo for it but was looking at going to a low mount setup as per the SBF. mostly I am wanting to go to a automatic once I start building more power from the turbo motor but would like to keep overdrive for these midwestern roads.

I guess a second side question that might need its own topic is can a C4 bell be modded for an AOD? or is the AOD a integral bell?

Looking at a GM OD auto?

I would start by laying the two different block plates on each other and comparing bolt location to verify if it is possible.

Then, if it's possible, use the block plates to locate all of the holes and drill all of the holes leaving the dowel holes a little small, center it up real good and use the block holes to pilot the reamer if possible. Remember the starter is referenced off of the dowels and block plate.

AOD is an integral bell.

8) 1/8" plate really isnt enough, mostly because you dont have enough thread area. 1/4 plate is much better, and i would use aluminum rather than steel to eliminate excess weight. you are also going to need to make a spacer to move the flexplate towards the transmission, it should be the same thickness as the adaptor you plan to make. again i would use aluminum.

If you want SBF bellhousing dimentions PM me with an e-mail, I can send you the cad file. I mapped a 302 out once as a project, and it's within .002" accuracy. It's just locations, not sizes.

Wouldn't you need a custom flexplate/ flywheel - 200 crank bolt pattern to the SBF/ 250 pattern?

Yep--the flexplate doesn't have a ring gear on it. Why Ford chose to put the gear on the converter, I'll never know.

Ditto
Get yourself an AOD with hydraulic valve body (Non Electric)
Not sure what year they switched E`80's to mid `90's should work, lots of Hi Po parts avail. Hard prt would be hooking up the TV cable (Throttle Value)
