Default Midwest XJS owner intro

Howdy everyone. I'm Jake, a freshly-minted Jag owner from Wichita Kansas. My car, bought last week for $2500 is a 1977 XJ-S with a Chevy 350 dropped in place of the V12 that was in it when it was purchased in 1978 from Scotland, Arizona. The car has the typical maladies: rusted out floor wells from the A/C condensation and clogged drain tubes, finnicky electronics, trashed seats, and vacuum leaks but the Chevy 350 and TH350 transmission does get it from Point A to Point B (albeit at a dismal 11mpg).
















The interior boasts a Nardi Classic wooden steering wheel and mostly stock interior in fairly serviceable shape sans the rusted out floor pans. The engine is a 350 bored .030" over with a mild cam, Edelbrock 600cfm four-barrel carburetor, and some exhaust leaks, the transmission is a 3-speed TH350 with a non-locking torque converter that results in 3000rpm on the highway. Fairly miserable, hopefully going to be ditched for a 4 speed with overdrive at some point.

Hopefully the floor pans will be replaced before the end of the month then I can get some sound deadening and carpets in the car, tune the carb up, finish repairing or replacing the electronics of the A/C (my current plan is to use R/C hobby servos and an Arduino microcontroller to modernize the A/C controls and get rid of the vacuum nonsense), make new door cards out of acrylic instead of the soggy cardboard, replace the 12 year old aftermarket stereo, and put some more miles on the car. Today I'm hoping to blow the clog out of the HVAC drain lines and fix a fairly obnoxious exhaust leak right below the driver's feet and take a look at stuffing some more, er, stuffing into the rather deflated-looking seats.

My other cars include a 2002 Mazda Miata SE that is my autocross car and currently-broken daily driver and a 1986 V6 notchback Mustang I bought my girlfriend as a daily driver and converted to a 5 speed manual.

Must be something wrong with your 350, because mine, even the way I drive (fast) makes 18 in town! You seem to be quite handy though, so I'm sure you can give it an attitude adjustment in that regard.

What is your setup like? I feel like the short-geared 3 speed (3000rpm on the highway!) has a lot to do with it. I need to get my hands on a borrowed wideband O2 sensor so I can see if I'm running rich, and by how much. I also feel my heads need reworked since there's a bit of vacuum flutter at idle that I doubt is caused by the cam (not lumpy enough) and is instead probably the valves requiring lapped and new valve stem seals.
