I am putting a TH350 in my 1979 Corvette, Trans from TCI, The engine is a 400hp 383 stroker, 336 rear. What stall speed converter should I get to get good street performance. Thanks JAY

2000-2400 if your drivn on the street any thing higher will be unpleasent to drive

Agreed. No reason to go with anything higher than a 2400 for your torquer-motor.

don't forget the trans cooler...lol

BS....

You can get a properly matched converter that will perform well and drive well on the street...

Depending on the RPM range of the engine, I would likely get something that would "flash" to around 3500 rpms....maybe even 3800 if you're gonna be running it on sticky tires and hitting the strip. This will likely be a 10" converter and will "foot brake" stall at around 2500....

If you get it from a decent converter builder, it will drive almost like a stocker until you put your foot in it....

Check out a few of these brands ($400-500):

PTC, Ultimate race converters, EDGE, Hughes

Some higher end brands ($600+) are :
ATI, Coan, Continental, Pro torque, Neil Chance...

I bet you would be fine with an EDGE or PTC for what you are likely doing with it..... Just stay away from off the shelf junk like TCI/B&M....

Same setup as yours as far as Th350, 400hp 383 goes except with 3.55 gears and mine is a 2700-3000 stall and runs just fine.. Nothing "unpleasant" at all..

I would match the converter to the rpm range of the camshaft, if the cam shaft comes in @ 2200 rpm, then I would want a converter in the 2500 to 2700 rpm range.

I bought a Huges converter for my stroked small block. Called Hughes and gave them the engine specs and dyno results of where engine made power. They took info and provided me with the converter they felt was best application for street driving. Figured if they are building them, they would know best, which application to use.

Bought a 2400 rpm B&M Holeshot for my 383 setup per advise from CompCams and forum. Can't tell you whether it's driveable or not though as it's far from done

Your TC should be matched with your cam !!! Between you cam specs and a good TC builder, you should come up with the correct TC.

Read up. Get smart. Make an informed choice. Ever notice that when you ask for advice on a forum like this, sometimes you get conflicting answers? At the very least, use your new knowledge to sift thru the BS.

This forum is great for Corvette specific questions, but for questions like yours, you're probably better off doing a google search on the subject. Not saying it's a bad question, it's just very general in nature. Also not saying you shouldn't ask questions like this, just saying you probably won't get what you really need, because nobody wants to spend 3 hours writing a post that will tell you everything you need to know. And, having a good, basic level of knowledge on a subject will make it much easier to understand the answers that you will get on a forum like this.

My setup is different than yours, but I am in the same boat as you are, in that I am trying to decide what TC to get for my planned engine build. It's a pretty murky subject, isn't it? In the end, you pay your money, and you make your choice, and you're the one who has to live with it, so do your homework, and make a good choice. Good luck!!

Thanks for your input JAY

call Hughes as they were knowledgable & helpful. have the folllowing info ready for them,
Cam duration
tire height
aprox weight of vehicle
crank horse power
rear end gear ratio
trans type
If you ever had the engine on a dyno give them the rpm that your engine made it's top/peak torque.
How you intend too drive the vehicle. IE: normal street with some spirited occasions, or strip or race.

They'll spec you out one as they did my 383 and I couldnt be happier.

I replaced my TH350 with a TCI Street Fighter (TH350) and used the TCI Breakaway converter which stalls around 2400. It has worked great for over a year now and is a 10" converter something they changed around the time I installed it since it was advertised as an 11"

Call the techs at any (or all) of the reputable converter companies and let the ask for info on your engine/car and make a recommendation. Compare results from those you call and buy from the one who seems best to you. Any other method is a "crap shoot".
