Around 180
For a 305 with a 4brl carb. it would be about 145 hp. For a 305 tbi it produces 215hp from factory. No, a 305 TBI is rated at 185 HP stock.
Chevy Caprice power rating for that year was 170hp.
Check on the carb.
1350-1450 @800rpms
On my 83 z28 305 it is 700 rpm
in the fuel inlet on the carb.
1. Pass., side, on the intake, below the carb.
Most 1987 models put out around 190 h.p.
If you have an edelbrock carb, remove the top of the carb, flip it over and there you have em! 2 floats! should be about 5/16 from the top of the carb i believe
Advertised horsepower is--- 155 HP @ 4400 RPMs Toqure is--252 FT.Lbs @ 2100 RPMs.
It depends on the year if in the 70's or 80's anywhere between 145-180
Stock carbs were usually 600-650 CFMs a 750 can be used but it has to be jetted down.
