Good set of 4.6 cams..

[voidfinger]

thats all cool, I'm curious about cams for n2o. Is there anything about the cam that is different? I'm keeping my auto and thinking of some custom cams. I want it stalled but i'm not liking the drivabilty of some of the cars that my friends let me drive with the stalls really high. I drove one with a 3200 stall... T/A and i liked it. but i drove a stang with a 3500 or 3600 and it just was to much... with exaust it sounds like your reving up to everyone...

 

[voidfinger]

^^ yea I def. undertsand that... i revved my 274's to about 6600

and the converter... HAHA i was on the stock converter still.

Never had a chance to get a stall in her... then i parked it to buy my 05 and then tore it down for my 4-valve swap.

Woulda ran much better on about a 3k stall...

You'd need approx a 4200 rpm converter for those 274's. The stock converter is 2400-2600,3000 would be like upgrading from a 2.73 to a 3.08 gear in the rear.
The 268's needed approx 4000 rpm,and mine was a 3500 rpm at the time-way too tight of a converter to launch right.

How can you tell if your stock converter is in the lower side of that number or the higher? if in the lower then a 3k stall would be a pretty nice upgrade ?

All of the converters are built identical. It's the torque output of the engine that determines the actual stall speed of the converter. A stock engine will stall the converter approx 2400 rpms. A modded engine will be slightly higher...EXCEPT those with longer duration cams-they make less torque than stock at the lower RPM-that will stall the converter lower than stock,and the car will have a lazy launch. A 3000 rpm stall speed converter is useless with a modular-a stock NPI 4.6L likes about a 3200 rpm stall speed,a stock PI 4.6L likes about a 3500 rpm converter.

Its just that i drove a 01 gt with a 3400 stall and the motor was stock and it had gears and it just wasn't what i would call street friendly... i don't know

Then,bluntly put-it was a POS converter that was molested internally to get a 3400 rpm stall speed,or a hack tuned it...or possibly-both.
My car has a 4000-4200 converter,and my wife even drives it anywhere,in any weather. It's not bad at all.
Proper converter build and tuning is a must. That's why you can't just buy a converter from anybody and expect it to be right-you get what you pay for.

well who makes good ones? i've been told dirtydog makes some good ones. He was on Corral, and thats where i heard about him. I just want something streetable and not to wild i guess... i'm not really keen on spend like 700/900 dollars for a converter either ya know.

You're gonna have to make you own decision on that one.

[bigjohnson4.6gt]

those shots are with the 1.25" spacers?

first one is, didnt know you wanted shots of the spacers, but they stick out a little bit from the rear fender, you can see how sunken in it is with the split spokes compared to the cobra rims

Anything look odd about it...?

[voidfinger]

Man that sucks, i've usually only heard good about them.

 

[DropTopPony]

To my eye i don't notice anything bad but i don't really know what i'm supposed to be looking for

Whats wrong with it?

 

[DropTopPony]

oh nevermind....its split
I couldn't tell because i had to scroll the picture side to side.
What caused that?

Not split-it's warped.Notice the upper section of the converter sits lower on one side than the other side of the lower section.Weak construction is my suspicion,but no matter-the thrust bearing won't last but a couple of minutes like that.

[DropTopPony]

So what or who's TC's are BC using now? I read that thread from the link above and it doesn't look like he and Alan are friendly anymore. I was planning on ordering one from BC this Spring.

 

[voidfinger]

so could you guys post up some links to some other good converter companies and tell me some issues with some. I've heard that "PI" converters had bad bands or something? i don't know, is that the only bad thing you've heard about dirty dogs converters?

Yea i see that now... wonder if it was like that when they put it in?

 

[Dalamar]

Depends on what your goals are with the car and where you want the powerband
to be.
Custom grind from MPH sounds good give Tim a call.

Goals are to squeeze out as much N/A power as I can. All motor ;D

Dont do it with a 4.6
:hammer:

I'm not expecting 800hp. I just want an all motor car. And I'm curious to see how much can be pushed out of it without a poweer adder.

Low 300's
beyond that is major work.
the Mod responds best to revs and boost.
