3.23s to 3.55s isnt really noticeable. 3.73s would be better but they are not available for all 3 cases IIRC. I like my 3.91s and would love to go to 4.30s but I have a OD 833 which helps a lot..

If you are currently running a stock converter, a converter change will probably make more differance than a gear change. A 280 cammed 383 would probably like a 3500ish 9.5 or 10 inch.

My 383 in my 70 Satellite is also a little lazy off the bottom. I think maybe just a bit too much cam in mine. I run 3.23's and have 275-60-17 rear tires. They measure right at 30". Last spring I put 3.91's in and ran them for a month or so. it helped it turn on sooner but it was exactly the same at initial start. I know it needs a converter, that would be the correct fix, but I am going to stay with the 1800 anyway. It runs pretty good from 2800 to 5500 or so.

sounds familiar.the bee has a 2000 stall in it.i am getting ready to put headers on it and upgrade the carb to a 750 cfm along with the posi and the 3.73.i hope its a different car.not that its bad now,just want to be able to burn both tires until i let off the throttle!

You may or may not burn both tires until you let off with a 2000 RPM 'verter. I'm running the Hughes Whiplash (0.518 lift, 229 degrees intake 242 degrees exhaust at .050) cam with 3.73 gears and 275/15/60 rear tires. It took some doing, but I finally got it tuned correctly and now can cook the tires from a standing start. Just standing on it, not doing a brake burnout first. That's with a 'verter that flashes to 2500 RPM. Not that I want to blow the tires off from a start, that doesn't get you to far to quick. If I bring up the R's a bit against the 'verter first it gets better traction. That way I'm not shocking the suspension and breaking the tires loose so bad. Just sayin'.
