65 Coupe 200-6 =)

New to these forums. I got directed here from some buddies at www.hotrodders.com :mrgreen: Anyways. I'm having a couple of issues with my 200 as it is, but also thinking about upgrading it a bit. I'll start with some history since I'm new.

Bought the car after Highschool with graduation money, wanted a '65 ever since I can remember and now my baby is sitting out in the parking lot! It ran for about 2 months after I got it and then the old engine gave out on me. I was dissapointed, but it gave me a chance to get under the hood and figure everything out down there (before I was real interested in wrenching, and more just wanted to drive it around), and give me a great chance to spend some time with my grandpa who's had a '65 with a 200-6 as long as I can remember (as well as a '56 Big Window F100 with a 272 V8, after he ran the 312 into the ground. After that engine keeled over, I bought a crate 200, still using the holley 1946? 1bbl, stock distributor, stock everything. After this engine swap, I fell in love with the wrench. Since then I've become a transmission R&R, spend all my time reading and learning, and can't get enough. =) This forum is great and I think I might have found a great new home for information!

The problem: My engine was running great once we got it fired up. I broke it in myself and everything, ran great. Ran real well for about 6 months, when my head gasket went out. I pulled the head and had it remachined because it was a little warped, new felpro gasket, sealed it back up. 3 months later, the gasket went out again. My timing was too far advanced and kept blowing out the #5 cyl. I fixed it. Now when I start the car in the morning, it rumbles and rattles like crazy, unless I give it a little gas, then it doesn't rumble for a second, and then starts rumbling again until I give it gas. When it warms up and I drive for about 10 minutes, I can come to a stop and it just vibrates instead of rumbles. If I hold the gas pedal down, it will sparatically go thump thump thump then go vroom again then thump back and forth, and it doesn't even out. I have a new distributor cap, wires, fuel pump, and stock coil. Still using the old distributor (which I might switch to a duraspark II after reading a recent post with a great guide), and the old holley carb 1bbl that's on there. I get black smoke coming out of the exhaust pipe when I hit the gas.

The question: How do I fix this rattle and rumble, and can I get rid of the vibration at idle under load? Once I get this taken care of, then if anything else comes up I can get on that. Thanks for your help guys. Also, I am thinking about doing some performance modding to my engine, but that 's for after I get all the kinks out of the running of the engine first. =) This is my first car, and I love it like crazy. I appreciate any responses, and sorry for the long first post.

Welcome to the board
Sounds like the carb.. Maybe a stuck float.. Black smoke is a sign of flooding. It could also be the choke not opinging up. With then motor warmed up pull the air cleaner (filter) off and see that the choke butterfly is all the way open..

Mike,

Since you now like trannys, think on this. The vibration might be from a loose flywheel/flexplate. That might explain the rattle/ vibration/ thunking.

You didn't say which tranny you have. Early automatics in Falcon were infamous for loose flexplates, but it seemed to get solved when Ford added more main bearings.


Good Luck
 
Ah, yeah. I recently pulled the tranny to rebuild it (C4), and my flexplate is tightened to spec since I put the new engine in there. I suppose it might be worth checking again. After about... 15 minutes of driving around it gets warm and goes from a harsh rumble to just a little bit of vibration. New mounts on engine. I was thinking it sounds like I need a new carb. The duraspark II and the carb should take care of a looooot of my problems. Anywhere in specific I should buy my carb from to ensure quality?
