This depends on year and what 305 and even in some cases what trans you have. 150 HP LG4 Carb 305. 190 HP L69 Carb 305. 215 HP LB9 TPI 305(1985) 190 HP LB9 TPI 305(1986-1987) 215-220 HP LB9 305(1988-1989) 215-230 HP LB9 305(1990-1992)-(91-92 were Z-28's not IROC's since GM Lost there contract with the Internation Race Of Campions which used the camaro's body design for their series from 84-89)
150 with the LG4 motor and 190 with the L69 motor. Both are 5.0 liter V8 305 ci. engines.
No, the 600 will not flood a stock 305. I am using a Holley 650 4-barrel (Model 4175, 80555S) on my 1984 305cid LG4. This carb is a Q-jet replacement, with 6 vacuum ports, electric choke and vacuum secondaries. The car runs perfectly with this carb although my fuel useage has increased since it was installed. However, that may be due more to my heavy foot than the carburetor. You can use the Carb Selector wizard on Holley's website (www.holley.com) to select an appropriate carburetor. The wizard said I should use the 570CFM, but that model does not have all the vacuum ports required for an emissions legal 305.
There were two engines offered that year. 84 Z28 LG4 V8 8.6:1 Comp/Ratio 5.0 L (305) Cu/In 150 h.p @4000 rpm 240 lb/ft @2400 rpm 4bbl carb 84 Z28 L69 V8 9.5:1 Comp/Ratio 5.0 L (305) Cu/In 190 h.p.@4800 rpm 240 lb/ft @3200 rpm 4bbl carb HO

305 SBC stylesThe 305 small block came with several inductions options over the years, including those witha 4 bbl. Rochester carb as well as TBI (throttle-body injection). if its still in the vehicle - check your VIN# [8th digit] H = Pontiac 305 LG4 G = Chevy 305 L69 H.O.
There are two trannys that were put into the 1982 Z28. One was a four-speed manual transmission, the other was a 3-speed automatic transmission. The manual shift was a Saginaw Muncie (code R) and the automatic was a TH200C. If your engine is a stock LG4 you probably have the 200C, if you have the higher output LU5, you might have the Muncie. Hope this tech info has helped. Most of this information can be found on Iroczone.com.
