it's sounding like a stock 383 Road Runner converter is not a bad choice for a street cruiser (Mostly). Not a bad choice at all.

Dacco #764 that I purchased many moons ago is behind my 383/432 Stroker
Absolutely love it on the street - Perfect idle as low as I want to go - Stab the go peddle off idle 700 RPMs and melt the 275-60R 15 tires as long as I am in the gas
Smooth and just works perfect for street use

I was told by many Mopar stock and SS racers back in the early 1970s that the 1970 383 two barrel converter was the best choice for a decent stock street and drag strip converter, not the stock street hemi converters   I've tried using a stock 440 motor home converter as a cheap way for better low price Hi Po converter, for street racing, the smaller (11 inch smog converters) later converters work better on foot stalling and having a higher foot stall RPM, around 2800 instead of 2300 to 2500 like the stock 11 inch street hemi converters had

You were misinformed, the 383-2 converter is a 12" (11 3/4") converter same as the 440 and the lowest stall offered. The 383-4 converter P/N 2801 764 is the 10 3/4" hi-stall converter which is basically a Hemi converter with smaller drive lug bolts.

Building a mild 438 for a 68 Road runner. Hoping for maybe another 100 HP over the 383. Had about decided to spend the bucks on a good converter. Way back in the day my 383 was near stock with a long duration Crower Monarch cam. Sounded and ran good, but with an automatic it was hard to hit a happy medium between idling in park and cutting off in gear. In my research it's sounding like a stock 383 Road Runner converter is not a bad choice for a street cruiser (Mostly). The 438 will have a little more lift and duration than stock, but under .500 lift and .300 duration. .323 gears, 70 series tires. Also back in the day and by accident I replaced the 440 converter in a GTX with one from a 383 Road Runner because it was what i had. The X would smoke the tires effortlessly with the smaller converter. I see converters rated at 2200, 2400, 2500, etc. I'm reading the 383 converter is already there. its now 2024 and converter technogoly has come a long way since the 70's and 80's. my opinion would be to call dynamic, ultimate or ptc and have a converyer built for you car, combo and intended use. be 100% honest about everything when talking to them.. the converter won't be cheap but the difference it can and will make is incredible.. i always laugh when i see someone dump thousands into a motor and trans only to skimp out on a conveter. the conveter can make or break the entire combination..

For a "street cruiser", no need to overthink the converter.

...It was not as quick at the track. But it drove well on the street... This last part here is the key: be VERY honest with yourself (and your converter builder) about what it is that you want!!! While converters today are very good, that high-stall ones will end up bit looser on the bottom end, they have to be...so if you absolutely can NOT tolerate that you builder needs to know this.
