Im going to be buying a 84 Camaro Sport Coupe in about a week and have a couple questions about the motor. Its a 1986 LG4 longblock, CompCams XE 262 cam, Edelbrock Performer RPM intake, Edelbrock 600cfm carb, Hedamn shorty headers and Y-pipe and will utilize a dual snorkle aircleaner. How much power do you guys think this motor is making? Also, how quick do you think it would run in the 1/4 in a sportcoupe with no options other than T-tops, TH350 trans with transgo shiftkit, B+M holeshot 2000 converter, 3.23 gears? Also, would a non ccc Quadrajet be a better choice for this motor? Thanks in advance.

Depending on how much work the heads have had done to them, that could be anywhere from 230 to 250 HP. It sounds like a decent combo; several people on this BBS have something similar, and get good results. So I'd expect it to go probably mid-high 14s, maybe 14.7 or so, maybe faster if the car's been on a diet.
You'd have to put on an adapter to use a Q-Jet on that intake. I doubt it would go any faster with that, but might get better gas mileage, but any of that would depend greatly on the particular carb you use. IMHO a Holley 600 or 650 with manual secondaries would probably be the fastest way to go.
