My cam specs and other info are below in my sig.

Can anyone recomend a more streetable converter for the off season playing on the street?

Or am I stuck with the 5K stall?

 

[MadmanMark]

Sounds like a screamer!

How about rear tire size and trans?

 

[dirtlips408]

For the street Im sure you could get away with a 10" 3500 converter no problem. Still would probably run low 11's at the track.

 

[fabio]

just wondering who makes the converter?

I dunno.... that's a pretty big camshaft he has for a 406 engine. Having a 3,500 RPM stall speed might make the car move very lazy and sluggish from 0-30 MPH

I have 31x14 slicks and the new 31x14 Mickey S/R Sportsmans for the street

The trany is a built MVB TH 350 with a brake.

I don't know who made the converter, it is about a 10" and light blue in color.

I sure would love to have a 3500 stall for the street, what kind would you recomend?

The ******* 3000 is tempting, but the ******* 4000 would probably be safer, if I go too small on the converter will it be a real bitch to drive at slow speeds?

 

[BillyGman]

If you go too slow with the stall speed, the car will not be difficult to drive on the street at all, but it will be slow and move like an old granny car when you hit the gas because of the long duration of that camshaft you have. it would be a BIG mistake for you to use that camshaft with a 3,000 RPM stall speed.

Thanks Billy, 15 years ago I would have bought one installed it and then found out he hard way

What cam could I put in for the off season if I want to run a 3K converter? Or would I have to switch manifolds and gears etc....

WHat would it do to my low 11's ?

Zach,

Dont want to break the bad news but In My Opinion you need a trinkle more converter for MAX PERFORMANCE such as true 5200-5400rpm stall

I have driven a 6100rpm stall on the street in my Chevelle with the 327 so what is the exact problem your having? My 6100rpm stall has been driven 28 miles non stop, Temp didnt get too hot. There are ways you drive a converter like this on the street that will make life happy on the street and at the track

Here is my 406 engine combo which is similar in camshaft but your killing me on power
- 400 4 bolt block
- stock 400 crank
- stock 350 rods with arp bolts, polished
- KB hyper pistons, with our heads, deck and gaskets 10.96:1 compression
- GM 291 heads bowl ported, no intake runner porting, no exhaust runner porting, no chamber porting
- Crane Saturday Night Special Solid Flat Tappet 256/264 @.050" .545"/.563" 105 lobe seperation installed @ 102 intake centerline
- vic jr
- 850 bg modified by us
- Powerglide with 5200rpm stall, transbrake
- 12 bolt rear with spool and 4.88's with 32x14.5 Mickey Thompsons

Best ET 10.41
Best MPH 128.42
Race Weight 2800

By the way, Who built your converter?

 

[MadmanMark]

I'd start calling some vendors, but it seems like your gearing might let a 3500-4000 unit work, as long as the car isn't too heavy. That's a lot of duration for a 406, so under 3500 might be a bit boggy at low speeds.

Swapping cams for the off season sounds like more work than it'd be worth. Too many other things are matched to the cam to get away with just changing sticks.

How high do you rev this? The combo looks like it's working pretty good by your times/speed.

 

[BowtieAaron]

i might as well be the first to say it... why not put a stick in it? lol

i would look into a lock up yank converter.
my friend drives a 4k lock up in his ta on the street all the time. worse part about the car is the bald DR's and the spool.

I'm running a Transmission Specialties 10" 3000 stall in my Vette with the 406. My cam is only [email protected] and .560 lift, but overall it drives fine. Been running it for a few years no problems.

Is it optimal? Probably not. But I can idle in traffic, and when I stomp on it there's plenty of fun factor. I'm running P295 50's with 3.70 gears, and it'll kick the rear sideways in second pretty easily when I'm on the throttle hard.

 

[mr 4 speed]

a tight 4000 9" stall would work

Or am I stuck with the 5K stall?

Can you post some pictures of your header setup
As for a converter that's alot of cam. I would look at a stick.

 

[the heckler]

acc converters (boss hog) has been very helpful in my choice. they are also reasonable and reliable...

Yeah, but what aboutm from a dead punch? from a standstill I mean.

You wouldn't neccessarily have to do a gear chnge, but I'm not sure about the intake manifold. You might have to experiment with that. The bottom line is that your car is obviously set-up much more for the track than for street driving, so to make it more street friendly compromises will have to be made. Personaly, I wouldn't use a cam with anymore [email protected] than 240-245 degrees if you're bent on a 3,000 RPM stall speed. The confusing thing is that you're trying to find ideas to make this combo more useable with a more street friendly stall speed, and yet you have a racing ring & pinion gear ratio. That 4.56:1 gear ratio in itself isn't going to favor street driving a whole lot at all since your revs will be up pretty high on the highway, and it will get kinda annoying to cruise at such a high RPM. At just 70 MPH your gonna be at 4,000 RPM and maybe even a bit more depending on your tire height. Cruising at 4,000+RPM is gonna get old real quick. Even around town 4.56 gears without an overdrive transmission is not going to be very fun after about 10 minutes of driving.

I think you're gonna have to decide whether you want to keep this car well focused for dragstrip use, or change it's focus to be more street friendly. Because it will take a lot to be changing it back and forth twice a year.

 

[zachscc]

I drive to work and the 12 mile drive is at a max speed of 50, usually 40mph. I jsut like to go 0 to 50 REAL quickly on the way to work, it cures the speed jones and I don't have to worry about speed traps.

The cops around here are pretty cool though.

I have also been dreaming of a New T-56 Magnum with the lovely .50 6th gear ratio.

But I would have to sell a motorcycle to pay for one, and that would make me sad.

So I will wait.

 

[Camaro_fever68]

Converters are a "get what you pay for" deal through and through. By that I mean if you get a good 5k converter there would be no reason to want to change in the off season. I drive a 5500 stall year round everywhere that behaves like a 3K stall when off the pedal, but comes alive when on the pedal.

A lot of cheaper 4k-6k stalls are very loose with normal street driving, making them a pain to get in daily traffic with. Mine is a Neil Chance converter and it behaves very street friendly and is a breeze in traffic. In normal driving instances I couldn't tell the difference between it and B&M 3500 I traded it out for.
