Hi everyone,
May seem like a basic question, but SBCs & Chevs are fairly rare where I am so it's near on impossible to find someone near who's Chevy savvy (Thank God for the Internet)

Have a 57 Wagon, have a good running 283 & powerglide from another car but want to fit a TH700R behind the 283.
283 is a 1957 motor so I'm guessing from what research I could dig up, its an bolt up deal
Thinking it'll have to be a new, much smaller starter motor to clear the steering (ahhh yeah converting it to Right Hand Drive)

I'm assuming its fairly simple but will need a TV cable set up & possible a new trans tunnel(?)

Have to get a new carb, the Holley 670cfm on its a bit large & thinking a 465 holley (stock motor, stock exhausts)

Anything I'm missing and is there 700r to go for preferably and one to avoid? It'll be a sedate highway driver
Cheers

The 700R4 should fit in the trans tunnel okay. They are about the same size as a TH350, just longer. If your 283 is a later model it should have the side mount bosses on it for motor mounts. It is best to mount the engine on side mounts and have one mount with a crossmember under the rear of the trans. Especially since the 700R4 will not have bell housing mounts. The 1988 and later 700R4s had better components than the earlier ones (more clutches, stronger output shafts, etc.) Make sure you get the TV cable adjusted properly. You can wreck the trans. before you even drive it if the pressures are not correct.
They had right hand drive ‘57s back when they were new, so the stock starter motor should work. They didn’t have mini starters back then.

Do a search of chevytalk for 700r4 conversion. There are more parts to buy then you think. Its been so long since I did the conversion that I can't remember what they are. 283's from 57 don't have side mount holes so you need turbo mounts on the bell housing and a trans mount under the tail shaft also. Too much weight hanging off the aluminum bellhousing without the mount. You then have 3 mounting points, front of engine(stock), turbo mounts, and rear trans mount. I know nothing about the right hand drive differences.

With the original 283, you will need something like the bellhousing mounts that Ecklers sell (part # 57-132222-1 ) and an added mount at the rear of the trans.
The next problem will be if you want to run headers in place of the original rams horns - headers will sit low if you retain the original trans mounts on the frame - but you could make up something similar to the Eckler's mid mounts and remove the original mounts and run headers.
Original size starter not a problem for RHD - we had some factory rhd V8's, and there is a large number of original aussie cars modififed for V8's over the years.

Cheers, Des

Here are 3 photos that show the frame horn font mounts that bolt to the frame horns, the rear cross member tranny support and the header clearance at the frame horns.
We have a 700R4 with Hooker Comp headers and Pypes stainless exhaust.
Hope this helps.

Is that exhaust a bolt together or weld, I assume its on a 55? or not, part number?

After the Hooker Comp Headers, the exhaust is 304 stainless manufactured by Pypes in the USA. The Pypes part # is SGC10. We decided to weld and buff the joints every where except at the entry and exit of the mufflers. We joined the mufflers to the pipes using stainless band clamps. Terrific product and the people at Pypes were super helpful. We received a couple elbows that were badly damaged and Pypes replaced them, no questions asked. The sound is awesome.
Our car is a 57 B.A. 2dr hdtp.

The Hooker Comp headers actually hang lower than the frame. It doesn't bother us though. We like the look. In this photo, the car is on jack stands.
