For the 518, you will want to talk with the folks at SMR Trans and purchase some of their upgrade parts to do it right. I built an A500 with all of their parts, and it wokrs awesome in my hotrod.

For EFI, if you get tired of trying to work out the factory set-up, I would suggest the FAST EZ efi....Love it.
