3000 Stall with 3.73's
 

I am looking to get a stall for my z28 with 3.73's in it right now. I do 90% stop and go driving so I want to stay small on my stall size and I was wondering if anyone had any advice on my choice of a Performabuilt 9.5 billet 3000 Stall and how it would compliment my 3.73's. I don't want to sacrifice my driveability which is why im staying small on the stall speed. I plan on installing a 228 TSp cam later this summer as well. Just looking for advice.

A 3000-3200 converter will do exactly what your looking for. Retain almost stock like drivability but offer a nice bump in performance when you put your foot in it. Also will compliment that 228R very nicely when you get around to installing that.

That's perfect. I appreciate the quick response. The converter I'm looking at is a Performabuilt billet 9.5 inch model are they as good as Precision or Yank converters?

its good but if u want reliability id go with p.i or yank u cant go wrong with either :D

Ill be honest I dont have in experience with the Performabuilt converters but Ive dealt with both Yank and Precision Industries, and they both make converters that perform well and are very reliable.

Is a multi-disk lock up overkill for a street car?

No, multi-disk is usually better I believe because it makes it smoother. People I have heard able about triple disk converters claim it drives just like stock, even with a higher stall speed

I can get a 9.5 inch billet Performabuilt 3000 Stall single disk lock up or a Precision 9.5 billet 3200 Stall single disk for 150 bucks more both have about 4000 miles on them. Any input on which one would be better for my application bearing in mind my car is a daily driver and spends most of its time city driving stop and go during the week.

I'm generally not a fan of used converters but I'd probably opt for the P.I. converter in your case. For what your doing a single disc lock up will work fine, and drive great as well.

Thanks again for the quick response. Been doing some research and most are saying yank or precision as well. I'll look into getting a new one. I need to remember the golden rule you get what you pay for.

No problem! Feel free to give us a call if you have any other questions or concerns.

I've got a cheapo piece of crap junk Revmax 3200 (which I love)that was a little too loose for my taste with my 2.73's but I just went to 3.73's and it feels much better in stop and go situations so I think you're on track with what you want. I also see why all of these guys with low gears think these loose converters feel almost stock. The gear tightens them way up.

I'm planning on going with a 3600 with 2.73's lol. I've never driven a stalled car before but STR goes into how tight/loose the car feels too. Eventually I'll be going with 3.73's in a new rear end with either a 228R, Torquer v2, or custom cam.

Im defiantly not going higher then 3200 just because maximum E.T at the track isn't my primary concern.

Foot braking my 3200 got 2600 rpms with the 2.73's. With the 3.73's only 2100 rpms. Keep in mind my car has just rolled 239k miles with factory motor and trans. Only mods are converter and as of about a week ago gears.

That sounds like what I'm looking for. Im leaning more towards the 3200 simply because I have the 3.73's already.

3200-3400 Converter... PTC is who I recommend.

Everyone always wishes they went bigger.

I've heard decent things about PTC but never looked at them myself. Don't think they're a sponsor are they?

Oh OP one thing to note is that not all converters are the same! I've heard a lot of people say that Vig converters stall up higher than they are rated. Shouldn't be an issue for you, it's usually an added bonus for people looking for all out performance that almost wish they went bigger, but noteworthy.

I concur, 3200 would be my minimum suggestion with 3.73s and the 228R.

With the cam you plan, a 3000 stall speed and a high STR
will give you a converter that hits hard and rolls over early.
Even with stock cam I could feel my TCI 3000 sort of "give
up" before 5000RPM. Now I run a 3500/2.0 which has less
of a hit to the tires off the line and drives OK (1500RPM
at 30MPH on level ground) but multiplies torque further out.
However this is not on the menu anywhere I know of. It's
kind of a shame that nobody supports the "road race" kind
of application for automatics.
