off corvette topic : transmission
Ok, I'm looking at building a future race car and would like to use a SBC since there are so many parts available. However I would like to create a mid-engine chassis, so the gearbox should be put behind it and connected directly with the axles. Is there a gearbox like this that fits the SBC ?
Thanks
Thanks

Some of the old kit-cars in the '70s used a ZF Trans-axle behind SBCs; the same type as found in Panteras I think. I've also heard of some kits now useing a Porsche unit (911 ?), but I don't know which one. Sorry I couldn't be more helpful, but maybe this will steer you in the right direction.

Old rail drag cars didn't use a drive shaft. They had a coupler for the transmission to the rearend.
Is this what you are talking about doing?

The transaxle is what you are looking for (I think), these guys have the bellhousing to convert it to a chevy bolt pattern.

At the PRI show there was a vendor that had what you're looking for, used in mid-engine race cars & off-roaders. Can't recall their name but I'll look thru the stuff I brought home. You can also Google the PRI show and look at the vendor listing description.

Answering on a old post : I finally found somthing : Hewland transmissions. They were basically once used on the can-am engines.
But boy these are expensive. I will have to look for a second hand one.

Recently read that the Porsche G-50 (found in ???) can be used behind a SBC. Also, that Chip Foose uses a ZF Pantera type unit in his new Hemisfear roadsters, so it must be avaliable somewhere. Good luck with your project.

transaxle
Many lambo replica cars use the 911 porsche transaxle. If you decide
to mate a sbc to a porsche transaxle you can go with a porsche 911
" 915 transaxle" provided that your HP and torque don't exceed 300.
If you exceed say 350 HP and torque you need to go with a 930
porsche transaxle. They are capable of handling 700+ torque. Porsche
made 2 kinds of 930 transaxles.
For 76-77 they made a short bellhousing 930 4 speed. In 78-88 they
went with a long bell housing 930. Both will work
The Porsche 915 trans were made from 72-86. The early ones were
made of magnesium and the later ones were aluminum.

I have more pictures of this locally owned and raced Lola F-5000 car.
They used a 302 ci Chevy (5000 cc) with 4 or 5 speed transaxle. Interesting cars from yesteryears. Kind of a poor mans F-1 race series because of the affordable Chevy 302's with 4 dual down draft webers. This thing dynos right at 500 hp. Which is more than it originally made back in the late 60's. You can only cheat so much.
