How much horsepower does a 350 have?

Answer 1

1960's had about 300hp

1970-73 had about 300-330hp

1974-76 had about 250-200

1977-81 had about 200-175

1982-84 had about 200-150

all this is depending on what bolt on's you have (Headers, intake, carbrator etc..). If its a stock 350 then it has lower horsepeower because of the years. If it's rebuilt and tuned properly it'll be higher

If you have bored the engine out then it would become a 355 or 383 with a stroker kit. Which results in alot high performance.

I have a 1977 350 which only made about 175 on the dyno when I bought it. I have since then rebuilt it. I bored out .030 (355) added a new crankshaft and new camshaft and lifters from Edelbrock, aluminum heads from Dart, Long tube headers from Hooker, tunnel ram from Weiand, dual Holley 600cfm carbs, and a new oil pan from Moroso.

Added up all I am making well 569 horsepower with this set up.
