1970 SBC 350 Transmission Questions
Revenant posted a topic in Gen I & II Chevy V8 Tech BoardFirst post! Before the witch-hunt begins, I've become quite adept with the search function here. I bought a JTR-converted '75 280z with an SBC 350 out of a 1970 Chevrolet Bel Air about two years ago. Searching on this website has helped immensely in getting this thing up-and-running, and fixing the bungles the previous owner made. My Z initially had a TH350 automatic transmission which, while nice in a drag, was not sufficient for highway driving. And I'm not planning on doing any racing. So it's currently on my garage floor, where it belongs. I've been looking at manual transmission options, and it seems the best route is to look at other cars that had the 5.7L V8...such as Corvettes and Trans-Am's. I'm thinking about getting a flywheel, clutch kit, and T56 transmission from a '93-02 Trans Am. I'd like to hear any advice from folks who went this route. My biggest worry is, given the age of my engine (i.e. it is internally balanced and has the two-piece rear main seal, rather than the one-piece) the newer '93-02 parts won't match up. Any wisdom / advice? Thanks all! Happy motoring!
Dropping a 350 in a 1981 ZX
Gaijin-Z posted a topic in Gen I & II Chevy V8 Tech BoardMy search for a good car ended up being pretty quick. I wanted a car that had a flawless interior, very little rust, but really did not worry too much about the condition of the engine or transmission because those are being upgraded soon. I lucked out and found a decent candidate, it was recently restored by an old navy guy but he wanted to let it go so he could fund a new corvette. It had very little rust, from what i could tell, the interior was in acceptable shape and the best part, It Ran! The only noticeable things wrong with it were some major dents in the frame rails from clueless mechanics jacking the car up over the last 30 years and a dull grinding noise when letting the clutch out which i am assuming is just the pilot bearing. I drove up to meet him the weekend after seeing the posting and ended up buying the car, this was late June of 2016, I was able to drive it the 250 miles home that day... kind of. My phone does not hold its battery very well and i was depending on the GPS to get me home, before i even made it to my state line, my phone died. This ordinarily would not have been a problem, but neither of the plugs in the car would work. I ended up stopping at a gas station to get a paper map and traveled like a caveman the rest of the way home. Then, the second i hit my county line, the clutch pedal just dropped to the floor and would not un-engage. I wrestled it into neutral and rolled into the nearest gas station. When i popped the hood i noticed the clutch reservoir was bone dry. Luckily they had some dot-3 for me to fill it back up and it lasted until i made it home. I would find the source of the issue later.
74 260Z 350
240z72 posted a topic in Gen I & II Chevy V8 Tech BoardBack in action! Came across this threw a friend of mine. 1974 260Z (11/74). Got it for a great price. Sat in a garage for about 3 years. Was drug out of a barn by my good friend about 8 years ago. He then swaped in the motor/ trans and ended up selling it before it drove, to the guy i got it from. He then carried on a decent swap. The car has a very nice COMPLETE aftermarket harness. Has very little rust. All of it is exterior. Flairs and fenders could fix it all . Original paint (and pin striping?). Has Eibach springs with Tokico adjustable struts all the way around. Larger Gen 1 Yota brakes up front. And a few other nice features. It goes down the road very nice. One of the best riding z's Ive had. Sadly the Motor dose have issues. It had a faint knock. And a few other issues I noticed after having it for a few days. At the time of writing the the motor is completly stripped. Will go into more detail later on what i found. (Bearings) Anyway Its awsome to be back and have a Z again. Heres a few pics. Currently has a lil beef under the hood. A small block Chevy Vortec 350 (1996??). Fed by a Holley Avenger. I was told its a 650 but Havent verified. Mated to a T-5 (from a camaro? Havent done the research yet). Which is spinning an open R200 (Ratio unknow still). Ahh the joys of buying projects. More to come!

1976 280Z with Chevy 350
Mr.Pink posted a topic in Gen I & II Chevy V8 Tech BoardI found a 1976 280Z with a completed 350 conversion for sale. The work looks excellent and the overall condition is great! He's only asking $3,000. However nothing electrical works. It runs and drives but the gauges, lights and wiper do not work. I was wondering if anyone had an idea what the problem could be? I'd like to buy it but not if I have to spend all my free time tracing down gremlins. Thanks!
Hello, I have a question for anyone who is running the stock or stock like aluminum 3 core radiators with their SBC's. What radiator hoses are you using? I bought two of the "universal" hoses from o'reilly's and my total was over $50. Just wondering if anyone could pull the numbers of their hose so I can see if I can find a cheaper option. I haven't put the engine in the car yet, so there is still time to return the hoses if other options are available. Thanks, Han
