Thank you Larry.
That's good to know!
For certain you could use the 95A (4-hole) 7" spread 3G.
From what I recall of the RJM site the 95's would consistently go to 125A output.
Bill linked a small case design 200A "upgrade" earlier in this thread.
These drop right in to the early EFI Windsor trucks that use the die cast top mount as well.
You don't need a die grinder or anything to make room for that smaller (135mm) case.
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
