318 torque converter

[ir3333]

the '69 shop manual shows the 318 converter stalls at 2100 - 2320
this has probably been asked,but for those running a 904 and 318 converter behind a stock or warm 340,what does yours stall at?

My experience with the low/po small blocks back then usually stalled in the 1700/1800 range. That 2100 - 2320 would be more representative of a stock 340 car in the real world.

Being how the 318 and 340 had the same stroke, and the torque at that rpm range was about the same, you wont see much over that with a 318 converter. IMO

P.S. I'm assuming we're discussing the rpm range against the brakes before the tires bust loose?

My duster has the stock 318 with headers and an LD4B. 2.45 rear gears . The stock converter flashes to 2000-2100.

You may have added a few low end lbs ft with those mods. Not surprised at your flash stall with some bite and the 2.45's. That's probably as good as it gets considering anything with a upgraded cam will hurt torque in the just off idle range.


As far as the OP's question, a few hundred one way or the other isn't going to make a lot of difference with a stock unit. If your looking for more performance with a stock engine, i'd look elsewhere for a upgrade. As much as the cheaper units are shunned upon, even a mild B&M or TCI type converter would probably give you some more juice with a stock setup.
