Post Stall Speed

There have been many posts on stall speeds and I still have a nagging question concerning the direction I'm going in my 2600# Ford PU. I have 400+ horses and 450+ ft#s torque driving a built 700R4 and a 3.36 rear gear. My tranny builder is old school B gasser that ran in the 6-7 sec 1/4 times years ago and is still sharp as a tack. When we discussed stall speeds for my tranny, he suggested being different since I was not going to compete with the truck. He said 1200 stall since the truck (and rearend) was so light. Well that's what is in it so as I get close to puting it on the road, I am soliciting many other opinions. Pros and cons anybody?

Cool

I'd side with your tranny builder. A higher stall convertor caused the rear of my '45 PU to continually break loose, when I switched to an RV convertor the problem went away (except when brain goes numb and foot gets silly}

Your tranny man is correct-except his car got faster in later years, my ol B/Gasser was a track record holder and couldn't come close to those times.

Cool

the older I get ,,,,, the faster I was.

Although I do not remember forgetting that part.

edit========= Depending on your cam shaft profile you may need a mild stall speed.

Sometimes with a moderate cam & a lighter vehicle you have to use more force on the brake pedal to hold the vehicle at a stop. A mild stall helps this.

Thanks for the input guys. Bob C and others, I would agree with those times, but he has a scrap book that has lots of info in it. Like he used to pin Warren Johnson and brothers ears back in their earlier days and beat the(60s) Nat champ three times in a row in the finals (was protested each time and was found legal the first two times, but was not torn down the 3rd time because he protested back and "Chump" would not accept). His two quickest cars were a 409 powered Henry J and a 427 powered 67 Camaro. A real joy to talk to and I have not caught him wrong yet! I want to scan some of his scrap books just to save some of the history.

:p

In 1970......Bill Jenkins set the ProStock ET record at 9.95

It fell as the years went by. They only now run as fast as the B gasser claims he went years ago. Now ProStock is 500 inches and a light car with vastly better tires than 25-30 years ago.


Sorry.......
