In my 85 383, I understand (based on the paper work) that the heads were done very well on the carbed 383.

I topped out at 109 at PIR last year, and that's with a stock converter that did not like that at all.... and a stock cam.

I'm keeping this car race only. Right now, it's got a 4.10 open rear end and a turbo 350.

So, it's time for another converter. It's also time for a cam.

How high do I go for the stall? I was thinking in terms of 3500 or so. This is for racing only.

Suggestions?

I would talk to whoever you get the cam from, they should be able to recomend a stall speed that matches the cams power range.

I would give a call to A-1 transmission in Vancouver. They do a pretty good job at spec'ing a converter and they custom make them as well. However, I'd advise you to get a locker/posi/spool before a different cam. The better you can hook up, the better your ET's will be.

That's a whopper of a trap speed for stock cam and converter. Cool

Sorry man, your wife's lack of confidence cracked me up.

Is this the same car?

Stock cam 383? WTF does that mean.

I prefer Continental converters. Or buck up and buy a Vigilante.

Never spec a tc without knowing the combo on the engine. If you plan on changing the cam change that and get the engine buttoned up then spec that TC

I bought a street edge converter 2800rpm, I have driven the car a few times since I have had it installed. It definatly wakes the car up. I havent really had the car out to much since it was installed so I can not comment on its durablity. Based on the reviews, I saw it should hold up well, it ran about $550. Definatly had a seat of your pants improvement and im running a smaller cam than you plan to.
