Your battery-to-starter cable is 8-gauge? Not 4- or maybe 2-gauge?



There's at least two ways. The popular way--posted on "famous electrical guy" web-site, will work...but he's screwed-up the...

What intake manifold are you using? If it's the stock '68 Pontiac manifold, does it have the open exhaust gas passage under the front of the carburetor? Do you have the special HIGH TEMPERATURE...

You want a load-leveler? Come and get mine. It was included with a used engine hoist I bought. I've never used it.

Load-levelers are a waste of vertical height, and the cheap junk engine hoists...

Depending on cam and compression ratio, that's so fantastically "good" that I would want to confirm that the gauge used is accurate.

Most (NOT all) compression testers use an Industrial...

Vacuum under the throttle plates is not the issue.

Vacuum above the throttle plates will not be lessened by opening the secondaries. Would likely make it worse.

The worst thing that folks can do to an oiled-gauze air filter is to clean it too often.
The second-worst thing folks can do is to over-oil the filter, especially on a vehicle using a MAF sensor. ...

The fitting in the intake manifold should be extra-long, with orifices allowing the fumes into both the upper runner, and the lower runner.

Maybe you have the wrong fitting. Pull it out for...

Decent drill motor, wire brush. Remove all loose carbon and rust. Will make the valve seats easier to see.

You are WAY over-thinking this.

"Priming" involves removing air from the oiling system--oil pump, filter, the larger oil galleries. It is NOT intended to spray oil over the fenders from the...

Dinosaurs all died 65 million years ago. Ten years on processed oil doesn't seem that much by comparison.

.031625 X 1.5 = .0474

But with .120 plunger travel, it won't matter.

I don't think it's anywhere near as critical as some folks have made it out to be.

That's .031 at the adjuster nut. Not .031 at the lifter plunger where it matters. You're not taking rocker ratio into account. The lifter plunger is being depressed more than .031.


Yes, IF...

I'd expect that would lower volume, but not pressure. May be so slight that you'd never notice.

Pressure is set via the internal spring.

If you readjust the choke pulloff, you also need to verify and perhaps readjust the linkage down to the fast idle cam.

You are WAY more generous than I would be. I'd cut those prices in half.

Remember that this engine was so disappointing that the previous owner cut his losses after twenty miles.

I'd be ten times more likely to cram-in a 4L80E or similar (4L85E) than to buy and build-up a 200-4R.

The '80E is inherently much stronger than the 200, but would need an electronic controller,...
