Mid Plate Questions

How did everything work out mopowers? Got her bolted up and running?

I hate to hijack but I have some similar questions so I hope you don’t mind if I ask them here.

My car came with a mid plate that seems to be drilled for either 727 or a powerglide. I’d like to use it if possible because 1. I already have it so it’s free ha. And 2. I know that it fits the car.

It is pretty thick (1/4 inch) so of course I am concerned about everything lining up. I could use a spacer behind the flex plate I suppose to move the TC back. Also the starter is another issue, I want to make sure it engages as it should. Is your midplate completely cut out for the starter or does it go through it? When used with the midplate I’m worried that it will be a problem that the nose cone of the starter no longer goes into the pilot hole in the transmission.

I haven't had a chance to finish mine up. I intend to just shim the convertor slightly with washers, then trim the midplate to allow the starter to bolt directly to the transmission. When I get a new convertor, I'll just have it made with thicker pads. I think that'll work fine with my .120" midplate.

Since yours is 1/4", I'd definitely make sure (a) the convertor fully engages the pump with a spacer like you said, and (b) the starter gear fully engages the ring gear on the convertor. Maybe do what my plan is and just trim away the starter mounting area of the midplate, so it mounts directly to the transmission?
