whats my Horsepower gain with these mods?

Which one? Those threads come up every week. And I obviously have no experience with modifying slants with 2bbls and exhaust, either.Oh, I stereotyped you as a V8 guy because of your comment AND the bright yellow car with "360" plastered on the flanks of your sig. I assumed it was your car. Sorry if I was mistaken.

im not going to get into a pissing match with you because you dont like my statement.those are my small blocks and NOT the only cars i own. the 360 duster is only one of my cars which incidently used to have a slant 6. i never said you have no experience and i did not attack YOU for what you had to say. you are telling the guy to dump a ton of money and work into his 6 cylinder to see any improvement in HP. no body said anything about swapping his 6 with a V8 except YOU. simmer down man , this is the internet.
