I'm putting an '04 GTO LS1 in my '56 Chevy sedan. It has a 4L60e, 3.08 gears, probably weights around 3200 lbs, has a Transgo shift kit, and a TR224 cam. Jesse at wait4me did the tune. I hope to start it for the first time by the end of the month.

I was telling someone who has a '55 Chevy with a ZZ4 SBC, Turbo 350, and 2500 stall about my car and that I put on a Vigilante 3200 stall. I know his car and mine are apples and oranges but he feels this is WAY too much converter for such a light car. He thinks it will be much too loose. I thought I did my homework and read several posts on the forum. Even though alot of posts on here are upgrading their converters in f-bodies, most of them say 3200 and even 3600 wasn't enough.

This is just a weekend car for fun on the street. No drag racing or anything like that but I read so many times that the two best things I could do is upgrade the cam and add a higher stall converter. The guy at Thunder Racing who sold the cam and verter to me said this would be a great driver.

I called Precision Industries and the guy just said "no, it will be fine". No explanation.

What do you all think?

your converter is fine. in fact i wouldve got a bigger one. imagine the old mans face if you told him you dd a yank4400

 

3200 is not a very big converter in the skeem of things, very drivable, it will drive around town like it's hardly there. Also when you get out on the freeway the pcm will lock up the converter and there won't by any slippage in the converter.

Also new school converters are much different than the old school converters, don't even worry about it, your going to wonder why all performance cars don't come with a higher stall.

 

Overdrive + lockup converter means you can confortably go with a higher stall than his setup. It will be a nice setup, I wouldn't worry! BTW I daily drive a Yank PT4000 and love it.

 

3200 is very tame in my opinion. It should drive real nice. I've ran a ss3600 in my camaro then i up graded to a pt4000 now. Keep in mind with a vig converter you always get one free stall speed change.

 

Whoo.....I'm feeling much better. I forgot to say that this guy emailed TCI with the same question and you know what they said? "You should just go with a stock f-body converter". HUH?

So the low-ish weight of my car and gears don't cause any concern either?

 

Lower weight easier on converter, when you get on the car it will make the car feel like it's got more gear. Trust us, you won't even notice the converter after a little bit of driving.

 

Thanks very much. I'll sleep better tonight.

 

Funny part is that you're going to get it all up and running, drive it around, and probably wish you'd gone with a 3600 instead, lol. Never fails. Whatever the case, you're going to love it. Oh and for the doubter (your buddy), just take him for a ride when all is said and done, and count how many seconds it takes for him to realize he was wrong. I'm going to guess it'll be within the first 5 seconds after you stab the gas and light up the rear tires for him. Have fun man!

 

Yeap just like all ^^^^said. I first had a 2800 stall, now I have a 3600 and love it. will never get anything smaller, I may try a 4000 next, I see nothing but great results with the 4000 converters. BTW most lighter cars like higher stalls. Its the real hevy ones that when you get high stall speeds it blows through the converter.

Just tell him you regret getting a 3600 and leave it as that..LOL

 

Lighter car equals tighter driving converter. The bigger converters tend to lay the smack down to the tires pretty bad meaning they are a lot harder to hook then stock. Since you don't plan on racing I would say a 3200 is perfect and will be a huge performance increase over stock. I personally would have chosen a 4k but I race more. I think you have made a great decision and precision makes good converters from what I have heard.
