Help with stall speed

I have a 83 Camaro Z28. 350 4 bolt TH700r4 trans and 4.10 gear ratio. The car is about 3300 pounds with a 600cfm Eddy with intake, headers and unknown cam. All I do know is its lopey, solid lift and comes alive around 3000rpms and pulls nice to 6000rpm! Stock converter sucks though lol. Dont blame me I bought the car this way for a great price and love it, but its a dog off the line obviously, and has idle really chugs it in gear where I'm going into neutral at lights. I need recommendations on using a 2500 or a 3000 stall converter or if there is a stock converter over the years that would work ok since I'm BROKE? The tranny is an 83 so it uses 27 spline like the TH200R4 if I'm right. Corvette, S-10 converter?? Any advise is appreciated!

To be honest I call hughes performance and get a reas on what I need..a good converter will be about USD 250.00 I have found and is worth it..but I would say it will take about a 2500/3000 rpm stall for your app..

I was looking through the Summit Racing catalog and wow! To retain the lock up function those converters are close to or if not more than $400.

Not knowing the cam specs doesn't help, but I'd say at least a 3000 stall speed TC, and 3500 prolly wouldn't be excessive- but you do have a steep rear gear coupled w/a steep low gear ratio in the tranny so you can get away w/as little stall speed as you need to not pull through the brakes when stopped.

Add the cost of a tranny cooler to your budget, it's a must-have.

Tranny cooler is on the list. As for little stall maybe a stock 2000 thats out there from a truck or something? Again it uses the same as the TH2004R because of the 27 spline input. Just brain storming here. I might pull the timing cover and see if there is some identification on the cam to what it could be. Thank you for the replys so far.

It sounds to me by your description that a 2000 rpm stall TC is not going to be enough for it to not pull through the brakes. And a 2000 stall speed sure isn't enough for good performance, either.

Bottom line is be prepared to go w/a 3000 rpm minimum stall speed TC. This assumes the timing and carb adjustments are already optimized for the cam. If the timing and carb aren't dialed in, do that first before buying anything.

The carb and timing are spot on. Any brands better than others? Budget is a key factor. I've heard B&M are not so good? OneMoreTime, you mentioned Hughes, should I go that route?
