I pulled out my gas tank today. It's full of rust. My new gas tank will be here on Monday. Wonder how much HP that will add?

A note with respect to the earlier distributors with the ball bearing type plate; Any current going thru the bearings to make ground with likely eventually "ruin the bearings".. How do I know? I've seen that happen with machinery when welding current runs thru bearings.

Now this is an informative post.
THANX!

No, they claimed a measurable (albeit small) increase in horsepower simply by improving the existing ground path. There weren't any defects or missing parts as under discussion here.

Somebody claimed they saw 2 to 3 hp gain or some such on the dyno simply by running a ground strap from distributor housing to block. Not a lot, though measurable. If the engine was audibly misfiring due to a missing ground strap either to the frame or within the distributor, there will be a lot more than a 3HP gain when the ground strap is put back in place.

Total advance does not usually include vacuum advance. He says "without the vacuum line" so it sounds like the 36 is without vacuum advance.

If it is a totally stock '57 distributor, then it should provide more than 36 degrees of total advance, closer to 45 degrees with 10 initial. It's either not stock or there is a problem with the timing light. However, I agree, if this is the way it's been and nothing has changed and it has not been a problem, then it is not the cause. Does that 36 Degrees take into account the Vacuum Advance? My understanding is total available Advance should be in the 42-44 Range. Initial + Centrifugal+ Vacuum.

The dial back timing lights can be quite inaccurate and that could be the issue. It is more than 36 degrees if it is totally stock. The mechanical advance alone should provide about 35 degrees @ 4000rpm.

Here is how I am determining the timing. Maybe I don't understand how this works, but it seems right to me. I have a newer Craftsman timing light, the kind where you can set the timing on the back with a dial. If I disconnect the vacuum advance line and dial in 10 degrees, at idle the TDC mark is right on the pointer. If I dial in 35-36 degrees and rev the engine to about 4000 RPM, the TDC mark is right on the pointer. This distributor is totally stock and has never been modified. I know that because I took it out of the lady's car. It has the points back in it now.
