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

I used to know everything once...but I'm not young anymore

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.

Friends don’t let friends drive Fords.

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.
