the engine is out of a 1992 ford thunderbird which i know has the restricked intake on it. i understand there low profile intakes and not designed for performance. as of right now i have replaced the belt driven fan with a electric one. installed a set of heddmen headers with 2.5" collecters(#88400), a k&n intake, a/c eliminator bracket, no smog pump, no power steering, no cats, and next im going to be running the exhaust back with a set of X-pipes and 40 series flowmasters. that thunderbird was rated and 200hp stock and it had 3 cats on it. how much hp am i looking at right now with no after market intake. and what would i be later producing with a set of 351 heads and a trickflow r-series efi intake.
