Several Questions about a 66 mustang
filed in 1966 Mustang
Question: I have a few questions about my mustang. First off, its a 66 with a 289 and stock everything.
1)The voltage regualtor for my gauges has gone out (none of em work) and i read in another forum that someone made a solid-state reproduction of this? anyone know where to get it?
2)At certain RPMs, the car vibrates pretty badly. At about 800, 1400, and from 2100-2500 RPMs the car shakes pretty badly. Not so bad i cant drive it, i just keep going and she smoothes out. At freeway speeds, its as smooth as anything ive driven. Whats causing this?
3)My rings are going bad. I know i should take the whole engine out and give it a complete rebuild, but I wont get the opportunity to do that until next summer when. I would like to know of any temporary fixes, or even if anyone knows a good procedure for an in car ring job. I know its been done with success in the past, but i would like to know how to do it before digging in there. I have my chiltons manual, should i just follow that?
4)Theres a junkyard a little ways from my apartment. In it i found a 1977 Bronco with a 302 in good cosmetic condition (no idea whats goin on inside) i pulled the valve covers off of it to replace mine (both were warped and were leaking oil) and it seems to have done a good job. I was wondering what other parts i could possibly pull off of it….I.E. What were the fundamental differences between the 289 and 302 besides longer stroke/bore/whatever.
5)When i do finally rebuild over the summer, whats a good rebuild kit for it? And if i find i need to….where can i find a nice rebuilt 289? The heads have already recieved a good valve job, so if i coudl just find the lower end, id be happy.
That should be it for now. Thanks
You can get these from any Mustang supply house. California Mustang Virginia Mustang Mustangs Unlimited National Parts Depot and many more. All of these places have websites and they advertise in Mustang Monthly magazine. In mid-1966 model year they changed from a 5-bolt bellhousing to 6-bolt. The blocks are different, so check if you are buying another motor., I’d suspect a leaky power valve, dripping fuel into the manifold while it sits, until the float bowl is empty. That’s why it floods. To change it, buy a power valve, the square gasket that goes with it (if possible) and a carb base gasket. Remove the carb, turn it over and you will find a small plate about 1/25 inches square secured by 4 screws. Remove the screws, then unscrew the power valve. Replace with new, etc. I think those are stamped sheet metal. Check with any of the Mustang restoration parts suppliers, such as the one in Oklahoma City.
