Converter For My Combo?

Doug Keen · 05-15-2011, 09:59 PM

I am torn about what to do. I built a new combo over the winter, it's a 496 BBC w/1.80 glide 4.33 gear in a 3400lb 10" tire car. The thing made good power on the dyno, peak tq was 704 at 5700 rpm and peak hp was 864 at 7000. My converter is a 9" and I have always wondered if I should be running an 8. It is NA. The thing flashed at 5000 last year behind a much "tamer" combo with more conservative heads and cam. This one is going 4800-5100 behind the new engine. Obviously it is a little lazy.out of the hole (okay a lot lazy) so I definitely have to do something. Should I go with a new 8" deal or stick with the 9" and have it reworked?

I always say loose is consistent! Even if it cost you some E.T.
with your small tire it could present a problem unless you got your car working right.
5100 is too tight I would say 5800 to 6000
we have ran 8" and 9" I would say stick with the 9" since you already have it, send it over to BTE talk to Bryan they will treat you right.

needs an 8" 6000 stall converter and not just any converter, an ATI 8" Treemaster.

Call ATI , speak to Charlie Plott and order it.

You'll be glad you did after reading your 1st time slip with it installed.

I would recommend an 8" convertor, about 5500rpm - 5800rpm. You will get a much harder hit with the 8" than the 9"...that's been my experience. I had a 496, now have a 572...had the 8" behind both and the 9" behind both. With the 8 inch I carry twice as much in the throttle stop as I do with the 9"because it is quicker in the first few hundred feet ....also, the wheels are up a foot with the 8" and only about 4" with the nine inch.

Just my experience....as far as convertors go...everyone has a preference. My 8 inch is a TCI and the 9" is a Coan....the combo is more important than the make....most preferences are due to people getting the right or wrong convertor to begin with.....Hughes makes a great convertor too, just a little pricey. Good luck!

the last four converters I bought were from Lennie at Ultimate Converters. Good service, good parts, completely satisfied. He is a sponsor of this forum, his contact info is at the top of this page.

I won a $895 gift certificate towards the purchase of a torque converter of your choice from ATI. The gift certificate was won at the Spring Fling and is good until 5-22-12. I am selling it for $700 which would save you $195 towards the purchase of the ATI converter of your choice. Let me know.

A YANK 3400 will work very well with your combo. Have a look at:
