I am going to do a trans swap in my Cutlass S 350 engine. Basic stock with a small RV cam. I am thinking of power glide out and th350 in. Would anyone have any advise on the best Trans and torque converter for that swap. I am not going to hotrod it at all, but would like it to spin the tires once in a while if I choose.

First off you don't have a powerglide. If its a 2 speed its most likely a jetaway (St300). The T350 would be a direct bolt in with the only mod being a kickdown cable.

thank you for correcting me, I did not realize I had to split hairs here to be understood. you are right it is not a powerglide it is a Jetaway. I also have chevy's so it's my mistake. both 2 speed, both GM. please forgive my ignorance.

This is my wife's car she had when she graduated from high school. she ask me to restore it. my wife passed away a year ago Wednesday. the car is now restored but she never got a chance to drive it.

thank you for your advice, I will remember it.

Wow, sorry to hear of your wifes passing without getting to drive her pride and joy. The reason I brought up the difference in the 2 speeds is that the ST300 has nothing in common with its Chevy counterpart. When you look for a T350, it has to be a BOP (Buick, Olds, Pontiac) bolt pattern. The torque converter stall is dependent on your cam and rear gears.

This will help too.

I just checked the diff & ratio. If I am correct it is a 2.78 gear (S3) and a anti spin rear end.

If its just an RV cam you can probably can consider an 1800-2000 rpm stall. You can probably run a stock converter also.

Stock rebuild on a BOP TH350 with a stock converter, good quality frictions, and a shift kit should do nicely. You'll have to get the accelerator pedal for the 69-72 A body with a TH350, kick down cable from pedal to trans, and bracket that holds the shifter cable to the pan (Jetaway one is different). Keep an eye out for a good core on Craigslist or at the junkyard and ask around for a local reputable rebuilder.

thank you for the advice 65DELTA. I was thinking of buying an aftermarket trans and torque converter. I am looking at JEG'S trans 60305 and TCI 241502 Saturday night special. would that be in line of what you are talking about.

oldcutlass

Both of those should work fine with a relatively stock engine and an RV cam. You can use the Chevy style kick down cable and carb bracket for your application also.

thanks for the advise oldcutlass and thanks for the links, that will help a lot in my project to swap. sorry for late reply, I have been out of town. my wife wanted to restore the car and drive route 66. I am going to take it for her.

oldcutlass

That will be a great tribute to her with the car. Your quite welcome, hope your swap goes well.
