Cam only automatics

What cam are you guys running and with what converter's. I would love to leave the stock stall but not sure if I can get away with it with the cam I want. What are all of you guys running and what kinda numbers are you putting down.

Don't have it finished yet, but I have a SS3600 and installing a G5x2 right now (232/240 112+4).

May have the converter restalled to 4000 if I think it warrents it. I'll just have to see how she works out first.

Stock stall is good up to around a 224/224 with 3.42 gears or so...you might be able to get away with 3.23s.

You'll probably make around 370rwhp with that.

What about a 231/234 cam with factory stall and 2.73's? That's what i'm going to be stuck with for a while, how is drivability going to be? Hopefully by spring i should have enough for a decent stall and gears.

That's going to drive like ****, be really lazy, and push through the brakes. You'll hate it. Best option is a converter that stalls around 3600, or at least put in some 3.73 gears.

I figured it would. Money is pretty tight right now, i don't plan on abusing the car until it's ready and thankfully it's not my daily driver. I don't want to waste my money on a cheap stall, but just like you said i will be in the market for a 3200-3600 stall and either 3.73's or 4.10's for gears.

Hell No. No sir, no way, no how. Not even with 3.73+ gears.

I ran stock stall with a 226/232 for about a week before the trans blew. To tell you the truth it wasn't as horrible as I expected. To put it in a nut shell, it "drove" but it was leaving some acceleration on the table. The car acted like (dare I say it?) it had vtec it would hit about 3000 rpm and suddenly start pulling hard. But around town driving it felt like I was towing something. I did have a tendency to stall at stops as well.

After the trans blew I replaced it with a Performabuilt stage 2 trans with a 3200 stall and the drivability is excellent. I think at this point I would have recommended putting in the stall before the cam. Drivability is extremely controllable with the stall. Although I have a soft spot for manuals, the stall makes the auto ALMOST as fun as driving a stick car. I even for the first time had to drive the Camaro in the snow and it was pretty tame even with what I got going on.

Get the stall, you may regret putting in the cam without it.

I totally recommend a stall before the cam. I recommend one for any auto car if you want performance.

Personally I think the SS3600 is the best bolt-on stall converter period. I would not go any lower or higher IMO. Tight enough for the street (and a light performance car) and cuts loose on the big end like a freight train.

With that Cam I would go with a PT4000 or a SS4000 if you are going to spray. (or similar - I lean towards YANK converters)

4000 on a 226/232 cam? IMO anything over 3200 is overkill for a mild cam, i'm actually looking at a stall in the 2800-3200 range, i don't want a flat out race car and i want to be able to make long trips in my car, maintain some drivability and reliability.

Yeah, any cam over stock I would go with 4000stall. SS series if you are concerned about it being too loose (2.5str), or a PT series if it doesn't bother you (2.1 str). The PT is more effecient on the big end and will pull harder.

I wish you were closer I'd let you drive my car with the SS3600. Full bolt on and 3.23 gears. Took it on a 400mi round trip the other day and it drives fine.

SS3600 is probably comperable to a VIG 3200.

How much did you pay for your Yank? I'm looking at some videos with 3600-4000 stalls, it doesn't seem that bad but the videos were pretty short. Is this the one you have?

Super Stock 3600 (245mm very high stall torque ratio due to 21 blade stator, hard hitting launch, 3600 stall, 2.50, 2.55 STR)
$879.99

yeah, I think I paid about 750 about a year ago... prices must have went up.

If you were really curious i'd post over on LS1tech in the south eastern section I believe and i'm sure there's somebody close to you that would have a 3600-4k stall.

I was unsure about the driveability SS3600, and now I wish I would have gotten the SS4000 (I want to spray a 200 shot on top hence the SS series)

Wrong. Maybe if you're talking about an LT1 or a Gen I motor that makes peak torque at 2500 rpm. You have to remember that these motors are detuned race motors from the factory. Big power, high peak torque due to heads with big runners (200cc stock LS1 heads that flow in the 230s @ .500 lift from the factory.) and a shorter intake manifold.. well, shorter than the L98....those are good for putting into dump trucks and towing/hauling.

The stock motor makes peak torque at 4200ish RPM, so you'd want optimally for street/strip driving a 3600ish on a STOCK motor...for more track oriented, you'd want a 3800-4000.

300 rpm below peak torque is the rule of thumb for converter selection. Like most things automotive... it isn't rocket science..

Thanks for putting it in that perspective for me, it all makes sense now. I will probably go with a 3600-3800 stall oh and it is rocket science for some of us Thanks Mike.
