Cobra Jet Cam?
In looking over the cam selec tion the CJ cam keeps coming up, you know the one, 206/221 on 115 LC, lift around .490.
How does this work in truck apps with 4-barrel, performer intake, and dual exhaust? How about with headers?
Cheap is in, I don't want to pay a lot or buy a cam that has no bottom end.
Who's used this cam?
Thanks,
Rich

I assume that you are talking about a 400.
A cam like that gives 427 ft-lbs of torque at 2500 RPM in a 400+.030, but it doesn't have much wind. It rolls downhill from there. Peak HP is 287@4000 RPM.

Yes, I'm talking 400. I assume more intake duration would mean more hp. But this cam must be better than a stock 400 cam, right? and the torque is still 377 lb-ft at the HP peak, gotta be more than stock. With my 3.00 gears the torque peak is around 72 mph.
But, how different would another cam with 214/214/110 LSA react? longer intake, narrower LSA should increase max rpm torque, possibly higher max torque but at say 3400 rpm?

Thanks, I appreciate the help. It seems that computers can generate so much information that it makes the choices more difficult. My situation is that when I take the top end off the engine to put the head gasket right end front, I may as well swap cams. The problem is, the truck is only a $500 truck so optimizing cam choice is a little less important than cost. The 214/214/110 is $37 without lifters, the CJ cam is a Speed Pro copy part number 650, I have seen them on ebay for as little as $5.00. So between the two I guess it comes down to what I can get for less, first.
Best Regards,
Rich
PS: If I were spending money on the optimum cam I'd have to go with Comp Cams XE series, they will grind a custom cam for not much than a standard cam. I'd look at a 5440 intake lobe, 206 @50, .498 lift, and a 5230 exhaust lobe, 218@50, .524 lift, on a 112 LSA.
