Info on stock '86 305

I just recently came into possession of a nice stock dark red '86 Camaro SC 305 (H-code), red interior. I've never been much of a Camaro person, but it's a decent car. 305 with 4BBL, auto 700R4, T-tops, no options at all except power hatch (even has the awful standard cluster gauge). I'm curious what MPG it gets, can't find the data. Also, what it'd run stock in the 1/4 mile.

It's definitely not going to be a racer; I have my Lightning for that. It's more for my 80-mile/day commute to work, where my Lightning just guzzles gas. But, it seems a pretty quick car for getting around town Are there any typical first/cheap mods.. the emphasis being on driveability and MPG rather than horsepower

My 86 Sport Coupe with the LG4 305 got about 18 mpg around town when in top tune. It would run in the mid-16s or so.

Go to www.thirdgen.org and look through the Tech Articles for relevent info.

just get a good tune, with new plugs, wires, cap, filters.

for some more power and a bit more gas milage you can do simple intake and exhaust upgrades.

look into a dual snorkel cold air intake box (seen an ad in the back of "car craft"), and a K&N filter. you could also try a carb spacer to give better combustion (not sure if it will fit under the hood though). and remvoe the cats (probably clogged anyway) and put a better flowing muffler on it.

you could get a complete cat back but with the low power of the engine in stock form i doubt you'd gain much to offset the price.

I'm looking up all this info now; now that I know what to look for I'm leaving the exhaust stock, though. I made that mistake with my truck... Bassani headers, Bassani high-flow cats, Bassani catback, EXTREMELY loud and droney:

Sounds good, but not for a daily driver. Haven't worked with carbs for a long time either... this is looking to be a good hobby car at least, to relearn this stuff. And the look is still growing on me... I'm a mustang man at heart
