Hello,
I'm restoring an old 67 GT40K that was raced at some point I was told.
And I've tried to do as much research on the missing bits as I can.
It is set up for a sbc 327 with the corvair/sag set up.
At one point I was told you can take the orig. trans off.
And plug a V-8 sag. right into it ?
Haven't tried that yet !
Sounds like you may have the Crown type adapter in your car.
That indeed does place the eng. way far forward.
I've found an old Kelmark adapter.
This requires the transaxle to be turned over, and turned around.
Witch places it as most all other transaxles.
Moves the Eng. placement back where it belongs.
Saves a number of inch's forward, And looks like it belongs there.
I think the Kelmark adapter is what they used in the orig. Manta cars.
I've seen two of the Kelmark adapters on ebay in the last three years.
I all so talked to someone that raced a V-8 corvair way back when ?
And after giving it a lot of thought,
He came up with another way to go.
He picked up an old ford top loader trans.
Had the main shaft resplined to fit into the diff. in place of the sag.
Had to make a flat adaptor plate for it, but he ran it for years with No problems.
Including a day at the drags, turning a run in the 9's.
The week point after that was the diff. case,
witch can be reinforced to keep it from coming apart under big hp.
Lucky for me, he had saved the shaft from the ford trans.
That I now have !
Don't know if this is any kind of help at all, or not.
And then too,
It's most likely you already know all of this info.
Cheers !
