street-legal (viz. emissions-passable) performance enhancements
From a Driver [not a Tech Expert like you guys]:
I’ve been reading outlandish-sounding descriptions in this board about how you all are swapping engines, swapping/porting heads, radically modifying intake, exhaust, boring out the block, putting in rumpity-rump cams, etc. – how do you do it and pass emissions? I have an ’81 Olds Custom Cruiser wagon with a bored, balanced and cammed 403 paired with a TH400 trans. [Her name is Mathilda -- ‘nuff said.] Emissions is not an issue because in her earlier life she was a Diesel [which is emissions exempt] and I just never got around to telling the DMV about the engine swap. Maybe next year…
Pops gave me his ’83 Merc Grand Marquis [‘cause he knows I’ll take care of her]. She’s a real charmer, but the 5.0 engine sure could use some help! I had to reconnect the EGR valve [Dad lives in rural VA and had no emissions worries] and acceleration is very poor [expecially compared to the above-mentioned wagon] even at the most optimal settings.
Would you be so kind as to give me some options as to what can be done to a Ford 5.0 of that vintage that would still pass emissions [from mild to radical]? I still would like to know how some of you fiends get away with what you’re doing! Perhaps most of you are building for the track.
