Which Chevy 305 v-8 has the most stock horsepower?

The Chevrolet 305 V8 with the highest stock horsepower rating was produced in the early to mid-1980s, specifically in certain high-performance applications like some Corvette and Camaro/Firebird models. The exact horsepower varied slightly by year and application, but these engines typically produced around 190-200 horsepower. It's important to note this was often achieved with higher compression ratios and different camshaft profiles compared to lower-performance versions of the 305. You won't find a single definitive number, as variations existed within those model years.
