How much horsepower does a 1975 Chevy V8 have?

in 1975 Chevy made more than one v8, of different cid.( cubic inch displacement)

first find out the cid. and then get the engine no. which is located on a machined pad in front of the left head. ( left ,standing in front looking at the engine).

you have to look up the eng. no. to get it right. your Chevy dealer may look it up for you if they are in a good mood.
