Hay this is not a super serious question, so please don't be annoyed. I have a '77 L82 that has had some modifications done before I got it. It runs really well. With my wife counting "Mississippis", I got it from 0-60 in about five seconds give or take. I know that the engine and rear end were rebuilt 30k miles ago, and that the trans was redone 10k miles back. I have a holly 650 carb, with a holy fuel pump. long tube headers that go straight to mufflers. A High spark system, an aluminum intake that for sure is not stock, and last but not least, a big cam that really lopes. Of course these are the only mods that I know of. I have not taken the engine completely apart yet, so I don't know if there is any thing else. But assuming that every thing else is stock, what would you guess my horse power would be?

Thanks for the help.

 

Probably should ask how much torque it's producing as w/ a lopy cam, you're losing out on the low end.

Best way is to take it to a chassis dyno and pay about $80-$100 for a reading. Or get a Gtech Pro.
