Torque Converter Reccomendation

1964 Chevelle ( Show car/ Occasional Track Use)
3:42 or 3:55 rear end gearing (in the future) stock 3:08 now.
Tranny Turbo 350

Engine:
355 cid sbc
Pro action 220cc heads
Vic Jr.
254/264@.050 .568/.592 flat tappet hyd. with the 1.6 rockers
Crane energizer 1.6 roller rockers
Guide plates
Cast crank with arp bolts on the main studs
Factory 5.7" rods with arp bolts
Forged pistons 11:1 compression

I dont want something tooo outrageous. B&M reccomends a hole-shot 3600. Edge Racing reccomends a 3000. Im lost. I dont want the tranny to be heating up bad, nor do I want it to be revving up really high in the freeway. Any suggestions or reccomendations would be a great help..

Re: Torque Converter Reccomendation

Well, I'm a huge fan of the Vig...Check out www.converter.com and give them a shout. They will walk you thru your combo and help pick a stall that will work for you...I like the "I don't want to be too outrageous.." then I see you have a 254/264 @ .050 cam..... I would think that you'd be looking at a 4000 stall, or higher depending on what rpm your peak torque is at...Generally for street/strip set ups you want your converter to stall around 900 rpm below torque peak...at least thats what Vig suggested in 1996...

The Vig is very efficient and is not supposed to generate heat like others....I have a 3600 that I've had since 1996 and I absolutely love it...5 tenths over my old 11" LPE, and drives like a stocker...until you hammer it, then

I would also think that you should look at at least 4.10s with that set up, maybe 4.56s. That big cam with numerically low gears and the 2.52 first gear in the TH350 would make it a dog out of the hole, imho...That cam is going to want rpms...
