Comp Cams
Got a 98 Convertible GT,
Trying to get a nice set of cams. And I was lookin at comp cams, the XE274H model 2000-6000 RPM. In the description it says 3.55-3.73 gears (got it) 2000+ stall, and computer upgrade recommended. What does the 2000+ stall mean and what kind of computer upgrade are we talking about?

RE: Comp Cams
Stall refers to the stall converter on autos. A 2000+ stall is recommended if you have an auto.
The computer upgrade will be for advancing the timing and additional fuel to see the maximum gain. The car should be tuned after getting the cam to get the best performance to begin with.

RE: Comp Cams
In attempt to put the stall in simple terms, the stall speed is in relation to engine rpm. A 2000 rpm stall, in a torque converter, begins to transfer engine power to the transmission at 2000 rpm. Keep in mind, your car will still begin to roll at less than 2000 rpm. 2000 rpm is when the torque converter wants to begin working with the engine power, which with the cam you mentioned, starts engine usable power at 2000 rpm. As far as the posted stall converter recommendation from Comp Cams. You want to go with a minimum of a 2000 rmp stall converter. This will also allow your car to idle without wanting the engine to bog down and quit running while you are stopped in traffic or elsewhere in gear. Remeber these are just basic terms. Most factory torque converters are rated from 1400 to 1700 rpm. Give or take 100 rpm. Hope this helps.

RE: Comp Cams
You don't want those cams anyways, your stock intake and heads won't flow up to 6k well, when the cam starts makin good power at about 4800 rpm your heads and cam are gonna be choking out. Your gonna give up some low end power with that cam and not pickup much top end. I agree you need a better cam, but your gonna have to step it down some and not be so radial - or you will be disappointed when you get em in.

RE: Comp Cams
I wouldnt go with comp, and according to the guys at modular muscle the comp cams are a bit to agressive for what the 4.6 likes.
Have you looked at VT? Other than the fact that i have been waiting on my order for over a month (they had some problems with the buisness being sold) they seem like the way to go. Good solid cams at good prices.

RE: Comp Cams
VT stage II's are great cams, but for a street car comp's 270's are outstanding. that's what i have, and i make over 300 N/A. they put down similar numbers as VT's. you cant go wrong either way. for a headswap, buy VT's stage II swap. best stuff out there. (i love braggin bout that. ) but if you keep the non pi heads, get the 262 cams.
