Torque Converter

[ibanezplayer]

I recently rebuilt my 1976 corvette engine into a 383 stroker, I'm now going to install a new B&M TH350 transmission. The engine produces 436 horse power and 471 ft. pounds of torque, I'm wondering what type of torque converter I should install for maximum street and strip preformance.

Thanks,

..... the more 'strip' it is, the less 'streetable' it'll be.


I'm of the opinion that as much TQ as your long-arm 383 makes, the less converter it'll need to get your car off the line at the strip:
what are your realistic-goals for the '76?

My goals are to have a saturday night special type of car, yes I'd like to drive it more than just that, but my main priority is to have this car be mean.

B&M reccomends 2400

B&M reccomends 2400

The term "2400 stall converter" is generic:
behind a motor that makes more torque, it'll stall a bit higher, and behind a less-torquey motor, it'll be tighter.

The 'actual' stal speed is determined by many things, including torque, vehicle weight, and gear-ratio, but I would think that a stall-speed of roughly 2500 would be adequate for your application.

Well to give you more information on what exactly I've done:
Brand new 3.70 differential
Brand new trailing arms
Brand new VB&P complete suspension kit
Rebuilt 383 stroker motor with Dart 200 iron eagle heads
Edelbrock Air gap RPM Performer intake
Holley 750 carb
MSD distributor and plug wires
Comp Cam # 12-422-8
New turbo slotted rotors from SS brakes

I plan to get the transimission taken care of as soon as I can figure out what I need for a torque converter.

That cam is gonna make a boatload of torque. I feel you are gonna want a converter that stalls around 2000-2400 rpm. Gonna need sticky tires as it should be able to shred the rubber at will.

..... what he said.....


The stroke, cam, and gears will result in a real stump-puller:
with all that smoke, I'd seriously recommend a 'built'-piece, not an 'off-the-shelf' item.

I have a pair of converters, one from ATI, the other from Transmission Specialties, and they are (practically ) indestructible, and I know, cause I've TRIED to bust 'em at the strip.....

i installed an Eliminator 10 from Yank Converters in my car. it is a 3800 stall that was built perfectly to match my chassis set-up and engine output. the guys at Yank are super professional, and it took just two weeks to build and ship to Alaska! i had a B&M 2400 stall in my car, it hooked good off the bottom, but it wasn't "fun" to drive after awhile. since i broke a couple teeth off the ring gear, i decided to replace the converter with the new flexplate. the Yank converter is a high effeciency unit. my tranny runs 20 degrees cooler and i lost rpm at highway speed. i used to pull 2800 at 60mph, now it turns 2600 at 60 even though the converter is a 3800 stall. my car slides gently into gear and idles worlds better at the light. street manners are greatly improved as well as the fun factor. now i can rip the tires anytime i want. using throttle control, the car launches harder. i'm sold on these converters, they nailed mine perfectly on the first go-round. the only draw-back is price. they run $800, but well worth the money. having ran both converters in the same car with the same set-up, BUY THE YANK!!!

I would replace the stock flex plate with a new heavy duty unit also. Also replace the flex plate bolts with ARP brand or equivalent. I agree that 2500 Stall is about the size you need. (3000 Rpm would be the max. but you may get some heat build up from slippage on the street.) Good Luck and have fun.
