I had this done to a stock one by someone else (who turned out screwed up the paint job so now the original stock one is back in but that's another story), and to the best of my recollection that was the only thing I changed between the dynos and got roughly 8hp. I don't think it by itself does as much as some people say it does. I would expect 5, 10 at the most. Although you might see more of a difference top end out on a highway.

I would say around .05 in the quarter mile maybe .1. But it definitley makes a difference in throttle response and if you gain 5whp from a free mod then its well worth it.

Maybe a .02 in the 1/4 at the most!!! If your only doing this mod by itself you shouldn't expect more than a few horsepower!!! And that gain in power my friend will make NO difference in your et.

I work at a machine shop and 70% of or work is head & intake porting....I've seen ALOT of ruined t/b due to people porting through the casting!!! You should be able to take it to a "decent" shop and get it done for $40-75.
