This is one of those areas I don't have a lot of experience with or opinions of. I've gone and built a beefed up 413 for Patti's '62 Newport and before I put it all back together I wanted to ask your opinion.

First year of the aluminum Torquflite. Everything was disassembled, cleaned and new clutches installed. Original 2:93 rear end.

It is a bit of a hot rod/sleeper I suppose but she has no intentions of going to the track with it. Daily driver with a big block.

Option A. Just reinstall the original converter and call it good. (80,000 miles on it)

Option B. I do have a 19 spline, 10.5", 3000 stall converter kicking around the shop that I could use if I swap the flex plate.

Option C. send the original one out and get it redone.

OR option D. ?????????

Thanks everyone.

Don't install the 3000 stall converter unless you need it. It will increase your fuel consumption and make the car more of a pain to drive. There is no upside to it, unless you need it for a wild cam that you have installed. The best option is to get the old converter reconditioned. There are places around me that will do it for around $50. That's pretty cheap insurance against getting debri in your new trans or against having to pull it out again because there was an issue with it.

The problem with high-stall converters and low numeric axle ratios in a heavy car is heat buildup, the converter will always be "slipping" at low road speeds and this builds up excessive heat. Best to stay with the stock converter.
