What you think? PTC, ProTorque, Circle D, FTI, Yank?

I have used PTC in a 400 before and after the first restall it was perfect and a fast converter. ProTorque supposedly has some magic figured out for ultra efficiency? Circle D seems like a damn good converter from an honest company who does their own R&D and machining? Yank SS series converters rip in 400-550hp cars I've tuned but no experience at my power level?

The car just went 10.96 @ 129.67 in Denver (8,100 DA) and I'm swapping to a built 60.

Who has used a lock up converter from any of these guys?

All the ones you named make good converters. It's hard to pick just one ya know.

Honestly I've always liked Yank converters and it seems they are often overlooked in the high hp world, but mine has given me no problems and I won't be looking to swap it out any time soon.

Opinions like everything else is exactly that. I have 7 sedan pro torque and no complaints. Like said all those listed are fine companies. They ain't Fuddles lol.

Just gonna say high buck converter in a ticking time bomb of a transmission. Its borrowed time and when it does go I think the chances are good to fix a contaminated converter.

Just more food for thought is as its an eventually spend the money on a 4L80e verter or a th 400 verter. But the investment is high so if you can save. Maybe that can be a better option.

Either way those are great companies so good luck either way.

Have you priced swapping a Vette to an 80 or 400? Not happening... There are many 60s out there running 8s and 9s and living fine. A audacity converter can be cut apart, cleaned, and rebuilt no problem... Not to mention you can easily run a filter before the cooler to catch any debris.

I'm not going to buy a cheap converter just because my trans "might" blow up...

Well you didn't state the car it was going in and majority of swaps are into f bodies. Race weight factors as well as street abuse and those tear up 60s.

Those 8 to 9 second cars that you talk about don't talk bout how many passes before it's "gone through" and those guys are freely talking bout it. Or rather how many they have on the side to swap in when needed.

I saw you mentioned built 60 trans going in I think it should be said like it has been said and the 1000's of post bout this transmission over the past 20 years is that your spending the $$$ either way. But like you said you have some limiting factors and prob I assume you are in possession of said transmission so if your committed I get it.

My first stop would be pro torque or circle D. Neal chance. See what options they have for the setup.

Can't Wait To See The results!

CircleD in my car with over 200 runs on it all in the low 10.00 range.

Why does da matter on converter choice? Does it effect their efficiency or something?

What's your engine combination? Intended usage? We can help figure something out for your vette.

I know two of the 9sec 4l60 guys and they take the trans apart at least 2 or 3 times a year but keep it hush hush just so they can say they do it with a 4l60

Thank you!

Yeah, screw that. I'll stick with my 80e as I've played that 60e shuffle too many times.

Hehe, just as I suspected.

But you have to admit that 4L60 1st gear really rocks.

To the original poster I'd get your car dynoed and give the chart to whoever is going to make your converter (along with your intended expectations on driveability, etc).

I have a PT4000 and been very happy with it. It stalls at 4,000 but will flash to 5500. I've had years of trouble free performance. It is surprisingly driveable on the street, just not so much at highway speeds (I have a TH400 along with it).

I've also heard alot of good things about Circle D too, you can't go wrong with them. I don't imagine your going to get a huge difference in performance between any of those, but the key is to get the converter matched to YOUR engine and your expectations.

How much you recon that goes on with some of these "sbe" motors that run amazingly quick and seem to survive forever??? lol

Rhetorical question.
