Well, hope you're not driving around without a tune. You really need a tune with that cam. It's really pointless to worry about hp before you get that done. I wouldn't be surprised if you were down on power from stock without a tune.

People have dipped into the 11's with that cam only. On average 12.0x if done properly. You'll need a real converter though.

And you know your A/F ratio and timing were spot on for "*******" it? Though my sources tell me it should rev to OVER 9000! (Only when it's cold though). Only after you quarter turn the rockers down though.

Yeah I bet you're making about 5 H.P. more than stock and getting some shitty gas mileage without a tune. Don't be lazy, get it tuned. Hell even a mail order tune would benefit you tremendously!

With a stock rev limiter you probably can't even hit the peak HP rpm for that cam.
Underdrive pullies work better on cars with belt driven waterpumps.

2600stall is a restalled stocker, you should go 2800+(lower limit for 9.5") in a quality 9.5" unit 32-3400 would be better even for a daily driver.

I wouldn't have any clue though I only daily drive my cammed Caprice to the tune of 20K miles a year. 2800 stall 3.42s was mellow enough passengers mistook it for stock till I got on the throttle.

X2, only no joke. Without a proper tune, your leaving a stupid amount of power and drive-ability on the table.
