whats my Horsepower gain with these mods?

why are you going to stereotype me as a "V8" guy? you have no idea what or how many cars or engines i own. that was not a "venomous" statement. adding a 2 barrel and a 3" exhaust tip with a chopped off exhaust and a K&N filter is good for next to no HP in an otherwise tired slant six. obviously you were not around for the last "slant or 318" thread

Which one? Those threads come up every week. And I obviously have no experience with modifying slants with 2bbls and exhaust, either.

Simply explain your statements in the first place. If you don't have time to write more than a smart-a$$ comment, how is the OP supposed to figure out what you're talking about and why?

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 AND the small block in your avatar. I assumed it was your car. Sorry if I was mistaken.
