I've been contimplating changing out my Dynamic 9.5"...4500 flash converter,to a 8" 5000-5500 unit. My 440's peak torque is currently 5200 rpm. I only put about 400-500 miles on the GTX during the season...May to October. I've heard both positive..and negative opinions in the past. I'd really like to lower my 1.54-1.58 60' times! Thanks in advance for your opinions! Randy B.

If your looking for a new one Lenny builds a great product an is super to work with.

Randy you could have your loosened up some but for
what you do with the car I think you would be wasting
your money with the new converter... JMO

Thanks guys! Maybe I worded my post incorrectly! I want opinions on using a "looser" 8" race-type unit on the street..without a lot of heat build-up...and slippage! Manufacturers are helpful too! THANKS! If possible,I'm going to do my best to find a used unit in good shape! I AM on a BUDGET!!! Keep your eyes..and ears open for me!

8"

I would not run an 8" on the street. For a guy on a tight budget, you seem to desire a lot of high dollar stuff.

a 9" J will be looser than what your running and work good on the street (thats what i run in the dart). my buddy runs a ultimate 8" on the street with no issues. 8" seems a little overkill on a 10/11 sec street/strip car though.

Charley...thanks for pointing out that OBVIOUS fact of DESIRING a lot of "high dollar stuff"! One can only HOPE to scrape up the money for car parts in a lot of cases!Simply because I'm seeking opinions,doesn't necessarily mean I'll be able to afford to get it..but,it's a possibility in the future!

I run a 9.5" Dynamic that flashes to approx. 4500 and my 3755# 440 Challenger pulls 1.45-1.46 60-fts. Ever consider that the reason your car 60-fts almost a tenth slower than mine isn't the converter?

Brad...I'm open for ALL your suggestions on knocking a tenth off my 60'! SERIOUSLY! Springs..shocks...slicks????

Hi,Randy! Do what I am...Alston ladder bars!!

ted whats a set up like that cost? my car is like Randys my car has run what is in my sig my frist time out but was only running 1.54 60 foot with the same converter.but my car fills soft on the bottom end.thanks mopar65

Can Jim (440jim) or Mr P Body,,post the equation for 60' and ET....it is pretty close,,,cant remember the formula..

That might give an indication of "how far off" the 60' is, if at all for your ET...

Guess I got treed.

Randy,i use an 8" vert that flashe's to 5400 and have no issues with over heating on the street. can drive most anywhere without any issues.

Well I guess after standing at the fences for two years, I'm building up a lot of desire, too.

Hi,Bobby! The Alston kit cost 1000.00..plus labor for the install...
