I thinking about fabricating an aluminum rear engine plate. In order to save myself some time, would anybody happen to have or know of anyone that has the shape and hole locations already drawn out and can email me the file?

.pdf, .cdr, eps, .cmx or .dxf will all work fine for me. Most other file formats will be entertained.

Why go to the bother of doing this? Is this for a race car?
 
I have the material and a machine to do it. Really just doing it for kicks and I get to lose a few pounds.

Gee and I thought the plate was going on the engine!

I have to agree with Bill, but I never try to question why someone wants to do something, I just build a S/C specific MGB bottom engine with custom 8.0 to 1 JE piston that is part of a $12-15K MGB drivetrain, so what the hey if you can afford it. :smile: That's kinda my thinking on the aluminum backplate, if you can afford it, then go for it, just call David Headley up and give him your credit card number. However if you are trying make one of these, you better be a darn good tool and die machinst, while getting the rough outline, and even the mounting holes drilled isn't that big of deal, you will have to bore the rear seal hole and better be dead on if you don't want massive leaks, definately not a garage project for most.
 
I knew the rear seal was the challenge. I've got a waterjet to cut out the blank and all sorts of milling machines to do the milling but I figured if I'm off a few thou. I might have a mess on my hands - er garage floor.
 
Well, it's sounds like you know your way around a machine shop, in that case, you could use a stock backing plate for a pattern.
 
We mainly use 6061 at my shop.
