I have a '68 Chrysler Newport convertible. 440 forged crank, 727 auto, 3.23 sure grip rear gear with Dr. Diffs Sure-Trac II center section. Car weighs about 4400 lbs. Low compression 440 built in late '72 from an RV with Stealth close chambered heads. I have this Lunati hydraulic roller cam in it: "Retro-Fit Hydraulic Roller. Great mid range torque and power. Likes 2000 RPM stall converter and works great in towing applications with lower gearing. Largest for inboard/outboard performance marine use. ;Advertised Duration (Int/Exh): 270/278 ;Duration @ .050 (Int/Exh): 219/227 ;Gross Valve Lift (Int/Exh): .515/.530 ;LSA/ICL: 110/116 ;Valve Lash (Int/Exh): Hyd/Hyd ;RPM Range: 1800-5800." Trying not to break the bank, but don't want junk either. I'm not racing, I just use it as a cruiser, and spirited runs on the freeway, not wasting time getting up to speed...;-). i've found couple of converters so far: https://www.ebay.com/itm/255661848983https://www.ebay.com/itm/334782511386And then there was a B&M listed on Summits page but it says not to use behind a big block. Anyone have any experience with picking a converter for a heavy car like I have?

The stall your looking for falls into the least expensive category but that doesn't mean inexpensive. I am Leary of the $259 unit on ebay you listed. ACC us out of Alabama and their converters used to be priced below B&M, TCI, Turbo Action etc. Probably still the case but I bet your still looking at $600. Allstar and Dayco used to be priced below the popular name brands too.
Keep old mopars alive.

Factory high stall is fine  Factory 2801764 is often ignored but very versatile.

According to Tom Hoover years ago at one of the old drag seminar that the Mopar drag engineers use to put on the best, the highest stall factory converter is he 1970 383 two barrel motor in a C body, better than the street hemi or HP 440 11.0 inch converters  I've never tried one or know of anyone who has  Tom was an engine guy. Whoever told him that was mistaken. There is more to converters than stall speed.

Any 383-2 would have had the 11 3/4" (12") lo-stall converter..
