Ok here's the deal I currently have a Vigilante 3200 stall converter, but I wanna go bigger. My current mods are LT's,1.6rr's, 227/233 112lsa cam, 30# injectors,3.23 gears( which are being upgraded to 3.73 at the same time as the converter) and a few suspension goodies. Im on a stock 10 bolt( yeah I know it wont last ) but I consistently cut 1.8x's 60' with et streets.
Now Im going with an Edge Converter and I can get whatever stall I want. So since Im going with a 4000 stall is a 4400 to big for my car at its current stage. Im gonna eventually get some heads later this year to go with the cam but for now this is all I got.
Oh yeah I've ran a 8.2 @ 88.9 mph in the 1/8 with that setup above.

 

You're probably going to have shifting issues with that stall. I would go with some 3.73s or 4.10s instead.

 

I would get P.I to restall the Vigi to like a 3800.

 

Sorry forgot to add I have a pcm4less tune set to my current setup and when I get the new converter in I'll be getting another tune to current the shift points.

 

It's not the shift points, but the high stall issue. With that big of a stall, you're almost guaranteed to have it.

 

What issue is that. Sorry Im a little slow.

 

It won't shift from 1st to 2nd at WOT with good traction.

 

Are you referring to the "stall wall" commonly found in ob1 LT1's with a higher stall. If so I had that problem with my 3200 and had it fixed with another tune by pcm4less.

 

Ok looking at my dyno chart my peak torque is right at 4000 rpm which 333 ft./lbs. So I think the 4000 would be the best fit for my car right now.

 

i would not go higher than 3800 with the cam you have and the gear ratio you have would not be enough,most cams from 230-244 require a stall speed of 3500 w/4.10-4.56 gear.if it was me i would get more gear first the stall you have now is sufficient...............

 

Yet again I get to read posts like this that don't make sense. A 4.56 gear would KILL him at the 1/4 mile track since he'd be hitting OD at about the 1000ft mark. Gear selection should be made based on tire height and mph in the 1/4 mile, you want to cross traps at the top of your 1:1 gear for an ideal setup.

Also, don't forget to consider the different STR's of a particular stall.
