The car is mainly going to be used as an occasional driver/weekend car that I plan on taking to the track on occasion. There's a slight possibility that it will end up being my primary driver because I don't do much freeway driving. Right now I'm figuring on a 11" TCI 2400-2500 stall and 3.55 gears (8" rear). I called Comp Cams help line and they suggested the 282s. Do you agree with their choice? I'm not sure if I will have enough stall and gear for that cam. If not what would you suggest, less cam (270s), more gear, more stall? I want to keep it fun on the street and still do well at the track. I'm hoping for somewhere in the mid to low 12's, seem about right? One thing I'm considering is a 3.80 rear because the car will not see very much freeway use, at least not for any extended amount of time. I have never driven anything with higher than stock stall so I don't really know what that's like and if it will become annoying for regular street driving.

Another thing, do you think a TCI stall converter will be fine for my application or should I look at another manufacturer?

Thanks for any help,
Brock

I agree with the 282S recomendation, it pulls hard from 2500 rpm to 6000 rpm in my daughter's 351w.

A 2400 stall converter should not footbrake any higher than around 2000 rpm. The advertised number is a 'flash' stall, that the unit might briefly jump to when coming off a trans brake or 'neutral drop'. Most people purchase converters only to find they don't seem to stall as high as they are advertised. This is why. For performance work on sticky tires, you would probably be happier with a 10" converter.

Yes, that 11" converter will allow the car to idle in traffic without lurching ahead in gear, but it won't be loose enough to take off all that hard. If all you have planned is street driving on radials, you'll probably be happy with the 11", but if sticky tires are part of your plan, you'll need a looser converter.

Good Luck?

Thanks again,

Back when we would use the old Vega and Pinto converters to save money, they would start out stalling at about 2000 rpms, and before the season was over, they would be stalling as high as 5000 rpms!!
Maybe the transmissions would just start slipping or something. I could be wrong.

Brock,
The 270s is what CompCams recommends as a replacement for the 289 HiPo cam. Just remember that the aftermarket heads will make the cam feel bigger than it really is.

BS

If slicks aren't planned, and most it's miles are going to be on the street, the larger cam should make taking off on the street easier.

It will launch on slicks better with the smaller cam, because it will make better low-rpm power.

The custom cam you mentioned is a good compromise, and should work well.

Good Luck!

Also, what about a split cam design? I have ported stock heads, I've been thinking that a spilt cam might work better.
