And there you have it.
Winter projects are always fun, but expensive. Start putting away some funds now so you can just dig in and keep working on it.

Sticking valve stem??? A friend recently bought a 396 car that had been sitting a long time. It would intermittently idle rough and pop thru the carb. He gave it a dose of Sea Foam or some similar product and drove it. It smoothed out and now runs fine. Just a thought....

I've had 2 cars with sticking exhaust valves in recent years. The clearance from guide to stem was just too tight especially when the motor got some solid heat in it. The first was the 427 in my Dad's car, the second was a customers 327. While wiping out a cam lobe is not rare, please don't short cut the process without making sure the rest of the valvetrain is up to snuff.

I know it's expensive and frustrating..........but so is doing it twice.

I ran Berryman B12 through it a couple months ago. Shouldn't be anything gummed up. It's definitely something I plan on really investigating.

The Chevelle has 255/70/15s on the rear compared to the Camaro's 255/60/15s. Just for giggles, I bolted the Chevelle's wheels on the Camaro to see the rake. Raised it about 1.5 inches, roughly.

The picture with all 4 wheels being Cragars was an edit, of course.

A couple of notes- one, the 'someday' goal is a little bit more rake than even this and either L60s or 275/60s (depending on whether or not I commit to bias plies) and to do that, it looks like I'll need new springs. Obviously, that can wait until after the engine is done.

Two, speaking of the engine, fret not- I didn't run it to get the car out. I just pushed it.

Lastly, you may notice Dad's new driveway.

No, he will not let me 'break it in' with a burnout. I already asked. Lame.

Don't be the first guy to leak oil on Dad's new driveway. Trust me on that, experience talking.

Haha, no mechanical work will be done on it there. Sometime this year we're going to drag it to my place so I can pull the engine.
