Last time I had issues with a flooding Holley, it was a center-hung float bowl; and the problem was the O-ring around the outside of the needle/seat assembly.

Of course, Holley doesn't sell the...

Oh, yeah. There's a company selling "form-it-yourself" tools using form-to-fit stainless steel "safety wire". My concern is that the wire will eventually cut/damage the hose it's wrapped around. ...

I have a love/hate relationship with Oetiker "Stepless" RE-USABLE screw clamps. (NOT the cheaper and more-common single-use "ear" clamps.) IF you can get them to fit your application, they're...

Describe what actually happens.

There is a giant diagnostic difference between "won't crank", "cranks slowly", and "cranks but won't run".

Does it:
Not crank?
Cranks slowly?

That catalytic converter is almost certainly dead. Replace the entire thing, not the flange.

For the record, hydraulic cams don't use "lash" so much as "Lifter Preload". You are not adjusting the valves, you're adjusting the lifters.


Yes.

Given any choice, I will drop the rag joint in the recycle bin, and use a U-jointed shaft instead.

This is a VERY common upgrade on GMT400-series vehicles, for example '88 to 94 pickups....

'75--'79 Seville, or maybe the '77-newer downsized units I might believe.

I'm REALLY surprised. I was sure a bigger engine would get a higher-torque-capacity axle.

The 8.5 is certainly better than any of the 8.2 axles; but I wouldn't want one behind a 455.

I may be wrong. I'm not an expert in Pontiac axle options, and I'm too lazy to dig out my Chevy references.

I'd expect that by '73 and perhaps before, the 8.5" ten-bolt would have been the...
