Does anybody has a diagram or blueprints for the bellhousing pattern of the chevy motors/trans?
I need to make an adaptor plate to fit a TH400 behind a Mercedes Benz 352 inline six diesel engine that will be transplanted into my chevy C30 dually pickup.
I have no clue where is the input shaft centerline in the bellhousing, this will be very useful to make both parts mate perfectly.
Thanks
Augusto.

I have a CAD file for a sbc at home. I will need to check if it denotes the bolt pattern (do not remember offhand).

nice. I want to do that too with a toyota 4 cylinder.

I'd guess the most delicate part would be to drill the 3 holes on the new engine's flywheel. Then mate those to the torque converter and you got your centerlines.

The spacer/adapter plate would have to take into consideration that the flywheel meets the torque converter when the converter is all the way in then backed out like 1/4 inch.

Does this sound right? like I said I havent done it.

you should not bolt the converter to a solid clutch flywheel, you must use a flexplate, otherwise the solid connection could damage the tranny's pump.
are you thinking in putting a Toyota 13B diesel engine into a chevy pickup? I'm planning that also for a friend's C1500.

"flexplate" - goodluck

Vega,
so you're thinking of bolting a TH400 to a 22R, I would say that is no a good idea, the 22R has not enough low end torque to work with the already low first gear of the TH400, your best bet for the toy is the AISIN-WARNER 3 speed automatic used OEM by toyota and Volvo, this tranny has the rigth gear ratio, the correct bellhousing pattern ( removable ) and a small high stall converter, also it fits manual bellhousings from toyota in case you come across one from other manufacturer, and finally is very small and ligth weigth.
