I don't want a loose converter, and have found a deal for a new 2400 stall from Precision Ind. for like 250 bucks or so. Would this be a good mod. I am essentially trying to decide between the SLP y-pipe and SLP LM OR this 2400 stall 'verter. Thanks.

A 2400 stall is a waste of money. If the converter is new or relatively new, you could buy it and send it to PI and have it restalled to a 2800 or atleast a 2600. The 2800 will have good drivabilty (especially if you 3.23 gears) and will provide much more gain than the LM & Y-pipe combined.

I agree with Ragtop. If PI is selling a 2400 stall converter for $250, it's most likely NOT one of their Vigilante converters. So if it's anything like the Yank Stealth 2600, you will be disappointed with the gains as they are very minimal. Step up to a Vig 2800 as a minimum or better yet, consider a Yank Super Thruster 3500 for the same price. Yank has them for 10% off plus they're throwing in free shipping last time I heard.

I totally agree with that. Take advantage of the ST3500 bargain going on! My friend with a '02 T/A convertible dropped .9 with her ST3500! <img src="gr_eek2.gif" border="0"> That was the only mod changed, and this is, of course, assuming that you have full traction. She was running consistent 13.7's with the stock unit, and her times plummeted to 12.8's at the time with the converter. She's since run a 12.60 @ 107 MPH with no other changes with the cooler weather. I'm getting ready to swap out to a TP4400. <img src="gr_stretch.gif" border="0">

BTW, the stock stall is only like 1500~1600 rpm's. (maybe more in the later years?)

I too would recommend the ST3500 for a bad *** street car. It is DEFINATELY not too much for a daily driver.

The key hear is you said you don't want a loose converter. It is true that a converter like a Yank ST3500 will give you great performance but it will also be loose. What is too loose for one person is OK to someone else. If you plan on drag racing your car at the track a lot go with a 2800 stall converter or better. But if you are not planning on taking your car to the track then a 2400 will be fine depending on the maker of the converter. I know of some guys who are running PT2400s and they cut a 1/2 second off their ET with this converter. Their cars drive like stock(no looseness at all) until they get on it.

I agree that the term "loose" is purely subjective. The best way to determine your definition is to drive someone else's car with an aftermarket converter in it. That will at least give you a starting point to know what you're willing to put up with. I've ridden in a car with the ST3500, and it's MORE than streetable for me. It's equally comparable to the Vig 3200 I have now for streetability, and I've put 5,800 miles on my car in 4 mos. with the Vig 3200 in. I can still knock down 16-17 MPG with mostly town driving if I keep my foot out of it, but what fun is that? <img src="gr_grin.gif" border="0"> <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

So would a convertor like this one be good for my LT1? My car is a daily driver and I don't really want a convertor that is really loose, nor do I have the cash to get an expensive convertor, keeping in mind an $800 convertor would cost me about $1500 CDN!

Hey Pat, Long time no talk. Do you still have your GTP?

IF you want a cheap converter for an LT1, the converter that came in 4.3L Vortec Trucks will bolt right behind your LT1 and will stall over 2,000 rpms...probably more than 2400 rpms. You can find them in boneyards for next to nothing, but for an even better buy, you may want to find a used Vigilante from an LT1 car for sale on Camaro Z28.com.

2400 is still low for an LT1. A PI 2600 or Yank TT2800 is as small as I would go.

Pat, I'd do a PI2800 my friends are going mid to high 12's in LT1's with boltons.

Hey Patrick! I no longer have my GTP, I traded it straight up for this Formula. The GTP was fun (13.78 at 100.2mph with just a pulley change and cone air filter!) but I missed owning an f-body too much! I wanted badly to get back into an Ls1, but the funds just aren't there right now.

I've heard that trick with the 4.3 convertors, and that's something I might do also. I know the Vigilante 2800 would probably be my best bet, however it's a bit costly and frankly, I don't want to spend too much on this car in case I end up trading for an LS1 in the next few years. So I'm gonna stick with lower cost simple stuff for now until I figure out if I can get back into an Ls1 anytime soon.

Anything below a 2800 stall isn't worth the labor. You'll notice little to no difference for alot of work!

This statement is true on an LS1, but not true on an LT1. LT1's don't need as much help on the bottom end as an LS1 does. I have a 2400 stall in my car and ran better times with the 2400 than I did on the 3200 vigilante that I had. I lost a hair in first, but gained big in 2nd and 3rd.

True that a 4000 stall on LT1 doesn't work well under normal circumstances.
For LT1s I normally recommend a Vig 2800 (or similar size stall) as a good all around converter. Provides a good gain and it doesn't cause problems with the PCM.

If you gained in first with 3200, but lost in 2nd, then you need more stall than a 2400. You need a 3200 that is more efficent in design.

A 3200 stall for an LT1 is perfect for my mods, I can't wait to get it.

Any recommendations for me?? I liked the Vig, maybe mine just had problems and wasn't working like it should have.
