I be been looking into a bb tune but have to wait till income tax so I have enough extra money. What exactly is a stall converter? Don't think I've heard of that

Yes, you will benefit from a lower gear ratio, and no, you don't need 35" tires to do it. The taller gear will lighten the load on your engine and drive train and mathematically change the number of times the axles turn in relation to the number of times the drives haft turns. Disregard anything anyone else tells you about this. It's not opinion, it's MATH.

A stall converter is actually called a torque converter, not a stall converter. All torque converters have a rating called the stall rating. It is the engine rpm where it begins to couple the engine and transmission, as the torque converter is the fluid coupler between the engine and transmission. A factory torque converter has a very low rpm stall rating. Performance oriented torque converters stall at a higher rpm. A higher stall rating benefits a combination of engine transmission tire size gearing and weight by bringing in the engine's power at the right rpm to launch the vehicle based on the engines torque peak.

In the end how much $$$ are you willing to put into the fun truck?

Weigh thr options and choose your mods wisely.

In the long run I don't mind putting some good $$ in. But right now just looking for some what cheap. Would a 4.10 rear end be worth it?

This is another thing I have been looking for to fit my truck. But all I could ever find was a weiland supercharger telling me i need a carb and my truck is SFI

So if I did change the rear end to a 41
.10 should I look into an upgraded TC too?

It's not necessary to do so, but all these things are going to free up some power/remove the sluggishness from it.

OK cool. I guess I'm gonna start researching and looking for parts and hopefully get that done eventually. I appreciate everyone's input on this. Because I'm trying to figure it out on my own and yall are the only ones I can ask for help/advice lol

 

[bai78]

Personally you should boost it, tune it, and go from there. That would net the most gains for the least amount of mods.

You'd need top end and higher gears once the 8-10lbs of boost kicks in.

Don't take our word for it. Seek out others in your area and get first hand experiences.

I've been looking for something to boost it and someone showed me procharger superchargers that would fit I think and I've heard other people talk about Whipple and wynjammer. Every time I try to look on summit or something I end up on weiland which says it fits my 99 but I need a carb and my truck is injected. So I get pretty confused in how to go about all that

Google this kit number for your application.

Check if Vortech has an application for our old trucks.

I checked out that procharger and that's pricey lol. Went to vortech website and didn't see anything under a 2001. So it looks like I got a lot of saving up to do.

 

[Archtoker420]

Another question for you guys is can you go from SFI to a carb?

 

[bai78]

Search around as you can always pickup a used kit. I bought mine for less than $1800 or so if I recall correctly.

I was just vigilant as well as patient.

 

[Archtoker420]

Well that's a hell of a deal cause new was like 6500 lol. I'll have to keep an eye out. Where did you find yourself at

 

[Archtoker420]

I looked at a wynjammer and it's pretty cheap brand new. Somebody on here installed it on a 99 Tahoe and had good things to say. I heard of putting a Whipple on a tbi but not exactly sure what that means? Is it diff from SFI

 

[bai78]

TBI = throttle body injection

Yes, different from the MPFI/SFI '96 - '00

Is there a way to swap the SFI or is that even worth a thought

 

[SUBURBIAN]

It is a good deal of work to swap away from the vortec injection and computer setup. Not cheap either. If you really need a power adder the wynjammer kit is very straightforward.
