Hello everyone, New member here, seems I've finally found the right place to talk to others about my Buick. I bought it to do some mild upgrades and flip it, but I'm thinking now I'll keep it (my other half wont be happy about this). It's a '77 S/R 2 Door Coupe, Limited Slip differential...and the bummer...a 305 Chevy Small Block. It's also an Automatic, but at least I've read these cars came with Turbo 350 transmissions. (Oh and I have A/C, which is cool from a selling stand point but I don't like it, cramps up the engine bay) OD says 89,322, my guess is it hasn't rolled over yet; the interior is way too nice for a 189,322 mile car. Other than this of course Not to worry though, I have new carpet for it and I'm ordering the floor pan soon. Replaced the brake booster & master cylinder, gotta do wheel cylinders now because I broke off a bleeder screw trying to bleed the brakes. Also I'm installing an oil cooler for the trans because it was free and the lines are leaking at the radiator so why not And another shot (I have all hub caps by the way) Okay now that I may have some of your attention, I have a lot to ask about this car and what to do with it. When I first got it, I wanted to slap on a 4bbl carb and intake on with some headers & glasspacks, fix the hole in the floor and list it for sale. I figured "Hey, it's a late '70's beater Buick with a Chevy (305 at that), it's automatic, pfff, just slap on some bolt-ons and try and make some huge profit off of it," but now I'm trying to figure out if it's worth more the way it is; low mileage high-trim model, and a LSD/Posi-Trac/Trac-Lok/whatever it's supposed to be called from Buick??? Did some reading and supposedly only 3,000+ were made?? I don't know and I'm confused. HOWEVER, I'm starting to find I want to actually do some upgrades that will do further good, but I don't know what to do. Camshaft? Valve train? Which would go with an intake, carb, and exhaust. What are good upgrades that don't require taking the engine out? I'm not looking for easy/lazy stuff like a lot of other people, I just want to know how much stuff I can to do to it, the right stuff. Originally I wanted to get: -EPS Performer Intake (2701) -600cfm Holley Double Pumper (Still up in the air, some tell me it'll work, others say with stock automatic I need Vacuum Secondaries) -In the case above; 600cfm Classic Holley (0-80458SA) Much cheaper -14" Round Air Cleaner -Schoenfeld Headers 166-3 (For the mere fact that they claim to fit in this car) -Two Magnaflow 18129 Glasspacks But by doing some research I've found getting all of that wouldn't gain a lot of horsepower in respect to price, so I'd need to get a Cam, and modify/upgrade the heads a little bit. What does that entail? :Comp: Thank you for looking, and I look forward to learning a lot about this car and what many others have done to them.
