Post FWD Chevy Smallblock???

Ok, here is my situation. I am building a dunebuggy, and I have a strong desire to put a 350/383 stroker into it. I dont like the Front-engine design, SO I am going with a rear or mid engine layout. I need a manual transmission that I can connect some how to the engine, but the transmission needs to have output shafts on the sides for the independent wheels, as in a FWD or even an AWD setup. Is there any tranny I could possibly make work? I have looked into using a normal trans and then connecting it to an independent rear suspension diff, but the whole setup is just too long to fit. Oh, and to complicate things, the motor puts out about 400-450 horsepower. Please help.

Have you looked into an old '66 Corvair Trans axle ? They used passenger car 4 speeds ( Muncie or Saginaw) mated to an axle with IRS. Mid-engine SBC/Corvair's were fairly popular back in the day with the Kelmark and Crown kits being the most popular. I'm sure there are still some floating around out there if you really look.

Or how about the Fiero setup ? Mounts the engine sideways and I've seen a couple with 406's in them in magazines and they claim the trans can handle it. Of course you couldn't put much tire under them so there wasn't much stress put on the transaxle setup.

Oldsmobile Toronado and Cadillac Eldorado trans axle. Automatic, but will handle the power easily. Small block should bolt up to mid 1980s and later models. Older ones will need an adapter, but they are available. 1990s Sevilles and Eldorados used a sideways mounted V-8, the 4100 or 4500. Not sure if they use the SBC bolt pattern or not, but I think they do.

I'm gonna say this just one time.... Porshe. Those transaxles are expensive as hell but they hold up under SBC pretty good. Do a search for some conversion info. There are a couple of companies that offer adapter plates and advice.

66-69 Corvair with FULLY synchronized Saginaw 4-speed. 65 & earlier won't work. The Crown & Kelmark conversions were mid-engine. Clark's had the remaining Crown set-ups, last I heard. They are at <a href="http://www.corvair.com" target="_blank">www.corvair.com</a>
For Porsche, try <a href="http://www.kennedyeng.com" target="_blank">www.kennedyeng.com</a>

Cool

A turbo'd LT-1 motor was hooked to a T-325 transaxle in a sand rail in our shop a few months ago.

You can use TransGo valve body parts and a Super servo for 2nd gear that fits a 200/200R4 tranny. Shim the servo up and use the accumilator springs in it too.

He was tearing up 2nd gear till we installed the servo and boost springs , etc.

When I see a V8 in a Dune Buggy its always mated to a VW transaxle via an adapter.
Just search for sbc vw adapter or something similar.

V8 to VW/Porsche adapters
www.kennedyeng.com
Beware, a V8 will destroy a stock VW tranny. They were designed for maybe 75 lb/ft of torque.

i wouldn't use the vw transaxle because my friend has a 66 bug with only a 1.9 litre and it ripped through his tranny in 6 days. sounds like an awesome project. maybe a cadillac northstar setup?

Mid-engine trans-axles

Two inquires recently for a mid-engine trans-axle compelled me to respond . Aesthetic Design Engineering LLC in Redondo Beach California builds mid-engine trans-axles with a Quick-Change differential section that can withstand up to 850hp in manual and 1000hp with a automatic configuration . ADELLC offers a kit for the late model Corvair not unlike the old Crown conversion . The ADELLC kit includes a sub-frame and complete coil-over rear suspension . Their prototype car they call the SuperVair has a 506cui Brodex Big Block in it which regularly aspirated is supposed to make 650hp on pump gas ...
