1983 Mercury Grand Marquis 2Dr "Mercules”

[Grand Marquis GT]

It was dark, but I finally managed to get my exhaust on. 2.5" all the way, already had the 2.5" off-road H pipe. I ran dynomax mustang midpipes (so they would bolt onto the H pipe without cutting), some 2.5" exhaust straights I cut to fit, Summit Polished Stainless mufflers (from the white car), and 2.5" dumps right at the rear axle. I will get pics sooner or later.

It sounds really good. A little quiet, but anything is after the open H pipe! An 8.3:1 compression 130hp 302 doesn't help either, lol..

I do really need to diagnose the rough running, as it represents a shitty drivability problem too. I suspect the TPS, I will have to test it whenever I get time.

Funny, I also ended up throwing a return spring on the hydro-clutched T5 that I happen to work on once. Idk why these transmissions always need that, none of the bigger shit ever gave me issues with zero add-on springy action, but these darn things, ugh!

Shame turbines only come so small and narrow. Some 16" or 17" dia in about 8" or 9" width would be pimpin

Sorry if I missed this but did you end up boxing the trans crossmember?

[Grand Marquis GT]

...not yet lol

Copy that. I see it turned into "how long will it last like this?"

Trapped the kid in the back seat I see. Won't work for long, he'll be strong enough to shove that seat out of his way any time now.

How old is he now anyway, about 2 ?

He'll be 4 in a couple months.

I got a great video of him shifting gears like he knew what he was doing. I may post it.

If he was also clutching you're in big trouble, better start building a 2nd car as soon as this one is mostly done.

Merc sounds good! Seems to have good tone with the muffs. Son playing Pokémon?

4? Jeez. When did we all get old?

Took this pile out for the last drive of 2016, to the grocery store.

Laid a nice 1-2 burnout coming out of the parking lot, and roached one of the coolant hoses up on the intake. Not fucking with it until I get back from overseas. Was still fun for as slow as it is!

[Grand Marquis GT]

So, my project for when I return is to build a 92-97 rear for the car. With that will include new ENS bushings, boxed control arms, and new rear lowering springs.

Going to go with 3.73s, 31 spline axles, and going to do a couple mods for strengthening. Hoping to find someone local to weld the axletubes to the housing.
