Hello all, I'm a long time Chevytalk member hanging out in the 58-60 forum with my 59 Impala. Recently my niece got married to a great guy who happens to be the second owner of a 57 4dr Bel Air hardtop (yellow body, white top, black and grey tuxedo interior). Today I was able to see the car. It's been under a carport for 15 years after the nephew had a minor accident. It was parked. Overall, it's in really good condition. My brother and I want to help them get the car on the road again (not necessarily restore it). We don't want to make the mistake of tearing it down to the bare metal and then take 15 years to get it back together. It's an original 283, 2-brl, with Powerglide. I'm assuming a 3.55 rear end. Non-AC, non-PS or PB. Pretty simple car. It has an alternator on it now.

We learned today that the nephew has a rebuilt 327, four barrel (unknown vintage) sitting on an engine stand and ready to install. However, we agree not to rebuild the Powerglide, instead opting for more modern transmission. We're trying to keep this simple.

I know the 4L60, 200R4, TH350/400 and 700R4 are the go to trans for modernizing the powertrain.

My question or request is what is your recommendations or experiences? It's not a drag strip car. We're aiming for a nice get around town and highway cruiser. I can't imagine the 327 is rated more than 250HP.

Here are what I believe we'll need:

Transmission
Specific torque converter
New drive line
New crossmember
TV cable setup
New AT cooler lines
Any kickdown switches, special carb linkages?
Four barrel carb

We also plan on a new radiator and flush the heater core so the rebuilt 327 isn't contaminated with old fluids.

So, what do you think?

Anything except a powerglide. A 350 TH would be my choice. Least expensive and bullet proof.

The Original Poster said he wanted to keep it simple.

For added driveability i would go with a 700r or 200r overdrive.

I agree about the driveability with an automatic 4 speed but be prepared to spend about three times as much as he would for a 350 TH. Thats what I'd put in a 4 door 57 Chevy. A Muncie M-22 would be my first choice if it were mine.

I have a 2004R out of an 87 Buick Grand National that cost me $1000 to buy and then $1600 to have it rebuilt with high HP goodies. The installation and retrofit is not for newbies. TV cable alone would eat their lunch.

A 350 TH would be more their speed but it is easy to spend other peoples money.

Thanks guys for the responses. It does look like the TH350 is more straightforward install vs. the overdrive trans I mentioned.

We're dragging the 57 to my house next weekend, so I'll have a better idea of what we're up against.

I'm still open to more opinions.

Good choice on the 350 TH. Keep us posted on your progress. Keep the questions coming. You'll get lots of help from CT.
