I have a 1992 z28 convertible with a good amount of work. Its a TPI 305, it has a custom burned hypertec chip, a SLP Air Foil, throttle body bypass, ac delete pully, s-10 heater box, K&N cone filter, siamesed intake runners, port and polished heads, a stock 350 cam, 1:6 ratio roller rockers, hooker headers, dual magnaflow exhaust with a x-pipe, corvette servo, 2200 stall, 3:42 gears, new posi unit, and thats all I can think of off the top of my head. Need less to say its not a bad running 305. It is running low 9's in the 1/8th with a 2.1 60 ft. The best part about the car is the exhaust, I got it done at Arkansas Performance Exhaust and they did an awesome job. When I get home I will post some pics on here and some sound clips if I can figure out how.
