So I will need an adapter plate to mate a SBC/LS engine to a Subaru 4EAT transmission. I am not going to spend $2000 for the one that is made by Subarugears, although I believe that it's worth the money. This will be as close to a zero budget build as I can get. I have access to not only the bulk material from a dumpster but I am going to be learning CNC mill programming at work and things like this would be excellent "scrap fodder".

I need a resource for the ridiculous stuff like this. Like "Here's the bellhousing for a SBC in XXXX design program" and "Here is the bell housing for a Subaru 4EAT", then I combine the two while locating crank centerline and bam Sv8aru adapter plate exists. 

I think that we have mentioned trying to collect the drawings before, has anyone found a real viable solution?

Do you have access to each right now? Maybe a cover plate for either? Might be the easy button. Lay them out on graph paper and just take the measurements.

In reply to Mr_Asa :

No I don't have access to any of the drawings currently, but I am just starting the planning for this.

Manual transfer and measure is my current plan.

In reply to QuasiMofo (John Brown) :

To be clear, I didn't mean access to the drawings, I meant the patterns via the actual parts.  Not sure if thats what you meant as well, but clarification is always helpful.

For the SBC I would probably ask the H.A.M.B. if no one here turns up anything.  Would bet money someone there had it

I've got SBC at work, can get it for you tomorrow. Have you googled these yet?

I know of a guy that made a motor to transmission adapter in layers !
 

he designed it so it could be laser / water jet cut in layers and then welded / bolted the layers together ,

Just an idea :)

SBC bell housing pattern should be cake to find. As should LS, which is not necessarily the same. I found this in 10 seconds: https://www.gt40s.com/threads/chevy-ls-bellhousing-bolt-pattern.31312/

I have a Subaru to VW adapter, which means I should be able to come up with the Subaru pattern if necessary. Not this week, though.

Hell this was on GRM already surprise Im not saying I hadn't Googled it, because I have both images saved but the ability to combine all of the resources is where I was going with the thread

I appreciate all of the help you all have given.
