Re: Piston rings

monzadon - did you confirm the pistons were hitting the valves? or is that what the previous owner told you? it really is an uncommon situation to have piston-valve interference in stock motors.

how did the engine run before you started working on it?

Re: Connecting rods

the rods can be installed with the stamped number down and it won't be a problem. you want the notch on the piston correctly oriented toward the bellhousing

Re: Wheel studs

No worries, just needed to know. You are about 130 miles from the Corvair ranch in Gettysburg, if you can't find one locally.

Re: Wheel studs

does anyone have an old 5 stud brake drum they'd part with so I can use as a template to drill new holes?
It would help if we knew where you were located

Re: I want to crush this Carburetor!!

There are aluminum plugs in the carb base that are there to seal off the drilled idle passageways after drilling. I can't find a diagram of the idle passageway but it is quite long. You might be able to figure it out if you study the base of the carb and where the aluminum plugs are. Removing the pl...

Re: 65 differential

Good luck with finding a spec as if you're forced to do a repair it's going to be some work. At the least, it will be a diff swap with one that has very little play. You could also do as Joel suggests above, and decrease the play by welding and machining the retaining nuts. You could also buy the Cl...

Re: Miking the cam

Yes, I have run used cams with numbers similar to yours. What are the condition of your lifters, specifically the base of the lifter? If the base of the lifter is concave you might want to consider replacing the lifters. New lifters on a used cam will work fine, lots of people will say it won't but ...

Re: Miking the cam

A new cast gear should be fine for a stocker especially with a 260 cam. As far as measuring the peak lift of the cam lobe, it's not square on the top, but ground with a slight slope to induce lifter rotation. Your initial measurements are typical of what I have measured.

Re: Isky High Lift Cam

It does sound like you have a performance cam. What heads do you have on the car? Any porting or modifications done to them? You can get a pretty good idea of the cam specs without disassembling the engine. You'll need a degree wheel and a dial indicator. Google "degree cam with heads on" to see som...

There is a local Corvair club there, you can find info at: http://www.unm.edu/~jimp/ Just my opinon: Your 64 can be made to handle well, I don't think changing to the late model suspension is worth it. Good s...
