[QUOTE="jonnybusa, post: 3158141, member: 574197"] Sorry, but thats just incorrect. There's no way an 8-9 HP increase can be had over shorties on a stock motor. Its just not moving enuff air to even make the long tubes worth it, w/ stock engine. If adding intake and exhaust parts, then a big 8-10hp gain can be had by using long tubes over shorties, but not one to the other. The HP/TQ gains fron going long tubes over shorties will not even be noticable until you add the other go fast parts to support the free flowing exhaust. Also, I didnt mean there would be a problem putting long tubes on a fox body like a stang, but in the lincoln, which we';re talking about, there are some slight differences that come up. Its just not worth the extra time/hassle and money installing long tubes, unless, like I said, you add parts to support them. If you add a mild cam, like the Ford motorsport E303, a ford lower and cobra upper intakes, and a larger throttle body ALONG w/ the long tubes, then the gains of the long tubes can be felt over shorties. In my one stang, the slower, 840rwhp one, a set of long tubes added 22hp/36 lb.ft over shorties, but I had the parts to help the long tubes max out the combination. [/QUOTE]
