Title: Stalls
Post by: bigkountry on July 29, 2008, 05:11:52 pm

I am ashamed to say that one thing I don't have much experience with is trans/ converters. So I am reaching out for your knowledge on a stall for my truck.

81 Scottsdale K10

I currently have a .030 over 400 with a mild cam and supporting mods. I am going to have the stock TH350 rebuilt with all the goodies instead of swapping over to the 4 speed. My intentions are to bump the cam up a bit and new springs to acomodate the new cam.

I am looking at this Lunati cam. http://www.lunaticamshafts.com/Product.aspx?id=2325&gid=297  or any other cam suggestions I will look at. I just like Lunati or Comp...lol

I am tearing the truck down and am getting a list of stuff together so when it all goes back together I am not waiting.

I already have a new set of 4.10's (front and back), I will be getting a set of headers with 3" collectors and continue with 3" pipe through super 44's or similar and dumped before axle. I also have a 750 Demon carb waiting for the engine to be re-done. I have  dual plane performer intake and full Accel ignition.

35x12.50's and a fresh TH350 with shift kit.

OK, that was alot of jumbled info but that is what I currently have or am planning on gettign for the trcuk when done.

What stall speed should I look for when shopping around with the listed mods going on my 4X4?

I have never had much to do with transmissions besides a shift kit, and I have always wondered how she would drive with a bumped up stall.

Thanks

The specs pretty much tell you what you need:
"This High Performance street cam likes 2400 RPM stall, 700 cfm carb, dual plane intake and headers"

the amount of stall you need should be based on the cam you select. most cams will give a recommended range. for instance, if your cam's power range is from 1800 to 5500 I would get a 2000 stall. a stall will help you avoid "boggy" starts.

I read the reccomendations on the cam, but assumed it was referencing a car. Since I am pulling a good bit of weight and different drivetrain configurations I was unsure if it would be accurate for my truck.

I am lost when it comes to this subject....lol

Thanks

with 4.10 gears and 35's, your geared just about right. the recommended stall should be fine. if it's a pure mud truck you could go a little higher on the stall if you wanted to, but even then it's not necessary imo.

Thanks for the link, some good reading there.

It will be a play truck, not a daily driver but will see some cruise time...since I cannot afford a vette (nor will the wife allow it) this will be my mid life crisis vehicle...lol
