Just curios on why. I have a Yank 3000 tt, and a custom grind cam on the way.

 

You will see a much larger SOTP(seat of the pants) gain.

 

wrong the cam would problely hurt u because u will lose 60' with a big cam with no verter to go with it a verter will help u @ anytime with a stock cam r not. i have seen guys pick up 3 tenths with just a convert no cam all bolt ons

 

Will a converter make much of a difference on the streets though? After the 4.10 gears, I have to punch it at exactly 20 or exactly 50 or it will bog down and fall on its face. I am tired of getting next to someone and making sure that I am exactly on 20 or 50 so I don't get embarassed. I want a gain at the track but I am more worried about making a difference from a roll so I don't get pulled by stock vehicles from a roll.

 

Yes, a convertor will fix that problem. It will get you in, and keep you in your powerband much longer than without one. Thus, more average power through the gears. A TR220 with a 2500-2600 stall with 4.10s will work great for a truck your size. Custom tune then you will be good to go. IF you go any bigger on either cam or stall, it wont be very much fun as a daily driver.

And, get the stall first if money is tight.

 

Would a 2800 or 3000 stall make more of a difference from rolling speeds on the streets? Sorry about all the ?s, I just want it to make a nice difference on the streets since I probably won't do any other mods until around December. I definately want something that will help out from a 30 and up punch so I don't look so bad.

 

i stall will also lower how much your rpms drop after shift so like said above, you will stay in your power band more. so yes it will help all around and then set you up later for sweet cam possibilities when the pocket book is ready

 

A bigger stall will generally hit harder and keep your rpms up through the gears, but in a truck with a mild cam and steep gears, you really do not need that much stall.

As a point of reference, your stall should match your overall gear ratio + your cam profile. "Over" stalling it will just cause more trouble with traction, and day-to-day, around town drivability.

Theoretically, you could put a huge cam in it and a 4000+ stall and you might get a few tenths if you are lucky, but you will curse yourself every time you get in the truck to go anywhere other than a staging lane at the track.

 

So would a 3000 stall be too much with say the tr224 cam later on with 4.10s or should I go with a lower 2800 stall? I already have traction problems so I don't really want to go to big and have more traction problems. Thanks for the info guys!

 

If you plan on stepping up to a 224 then a 2800 will work for you if you feel you want the best compromise between drivability and performance. Just prepare for your gas mileage to drop quite a bit in town.

The difference between a 2800 and a 3k stall with that cam and 4.10s would be negligable at the track. If you really think you need a 3k+ stall then you might want to look into Yank's SS series convertors. They run a differnent stator that makes them run a little tighter for street driving.
