awesome! Thanks for the reply tj! I keep hearing more and more good thigns about these converters.. i'm just going to wait for a GP/sale/or get a used one.. It will be the PT or SS series 4000 for sure! Thanks!

 

Save your pennies and get the Yank. I'm on my 4th in 2 cars and never had a moment's trouble with any of them.

WOW what a difference in how the truck 60 foots...
I made 7 passes On the SS4000 in one night Every single one had a 1.55x sixty foot. Slowest pass was 11.70@116.1 Fastest is shown above So the converter is very consistant.

Hope this helps you with your decision..

YANK rules
PS... Just ordered my 5th yank converter

 

I have to say the SS4000 gets my vote.

 

bringing one back from the dead here aren't we fella's?? I might as well throw my 2 cents in and say I'm really looking forward to getting the pt4000!!

 

Well we are not on that list but we do average a 96 percent efficency not to bad IMHO

 

Circle D Specialties would be my first choice.

Torque converter selection is one of the most important components in having the right combination. Pick wisely.

Good luck!

 

I would take a look at some of the pics these guys posted. I was impressed so far.

 

Yanks got my vote.

 

I have never heard of a yank PT4200??? PT4000 and PT4400 and they use to sell a PE4200 but not a PT4000???
