11 sec. build cost?
I don't know about the rear. Certainly stock axles and slicks don't get along.
If you want ET, its holley. If you want street manners and E-Z tuning, get a Street Avenger carb. Cheap, easy and capable of good ETs. I run/ran a 670 on mine.
Have you already got that camshaft?
Don't forget the trans cooler with that converter.
Manual valve body would be a big help ET-wise, but then you're probably stuck buying a shifter, and some people don't like to drive them on the street.
I run the whole cal-tracs setup on my car, along with new poly shackle bushings. I wouldn't get their front shocks though. I had them and they made the rear end really floaty in the street. Didn't seem to help 60' times either.
