I know, I bought a MSD street fire plug wire set for 302/351W. They were all long! especially the drivers side, the drivers side goes along the engine and around the front with length to spare! I'm going to make those short enough that they go over the valve cover. Also it looks like I forgot to plug in my #5 plug wire the other day, or at least all the way on. After I get these trimmed I'm going to check for a dead cylinder, it doesn't run like it has one but with that engine you never know, I've gotten the firing order wrong before and it still ran smooth. I left my passenger side ones with a tiny bit of slack, but they are all better looking that before.

SO today I changed the oil, shortened my plug wires, got a vacuum reading and at 600 RPM it was 18" and when I revved it up slightly it was 19-20". I also discovered that my fuel pressure is 10 PSI! looks like I will be buying a inline regulator for it. Should do pretty good on gas then, 10 PSI out of a mechanical fuel pump? I was expecting 6-7 PSI MAX.

I wasn't quite done yet with making them neat, they are a little bit neater now.
Also I still haven't gotten the time to paint the valve covers, I'll just do that in the spring I guess.

That reading on vacuum at 600 is reasonable if you have a non-stock cam in it. (I forget what you said about the cam.). But, on a stock cam it should be more like 20". And, as I said on WHYDTYTT, the Summit regulator appears to be a Holley but at less money.

When I had the intake off the cam lobes and in between the lobes were a shiny bright metal, I noticed some different cams are made with different finishes and or metals. But the lobes looked like new when I could see them down through the oil return holes.

Sounds like you have a new cam. Did whomever put the manifold and carb on also put the cam in? And, I agree it would be nice to have it stamped on the end. I measured my cam 12 ways from Sunday and still don't know what it is.

I just bought the summit regulator, when I get it I'll have to go find a couple fittings and a plug for the second outlet
Oh yeah it had the original manifold on it when I bought it, the guy gave me that one in a box.

I might do that sometime, but after I get the exhaust done I need to start saving my money for insurance and stuff.

Something I find very weird is how can my engine have 10 PSI of fuel pressure but never flood over or run like crap at idle? weird. But it should do better with the regulator.

Is that pressure in the lines or coming out of the carb? The restrictions of the needle valves might be keeping it from flooding? But that much pressure might be causing it to have bad fuel mileage as well.

I hooked the gauge up to the end of the fuel line, started it up for 20 seconds looked at it and then shut the engine down, it read 9 PSI after sitting for 5 minutes and stayed there.

So today I cut open my old oil filter, looks cleaner than the last one. For some reason my camera makes the pleats in the filter look more separated and wavy than they really are.
The filter is a Purolator Classic L30001.
Also the last two times I have been to Walmart I have seen a 20 year old Fram PH8A new in box on the shelf, today I saw one for an Isuzu that had a 1991 copyright date on it, how do those make it to the shelves that late?

Copyright would just be for the art, pattern or design of the box.
I don't imagine there's much new about the box, or a reason for them to change it.
Do these things have a date of manufacture stamped on them?

Google Image Result for http://i.ebayimg.com/t/FRAM-PH8A-FORD-MOPAR-OIL-FILTER-/06/!B0s54pQ!Wk~%24(KGrHqZ,!iQE)qpzSRpHBMb,CgFW5w~~_35 .JPG
They look like that, way different than the ones made today. They were crap back then too! and that was back before Honeywell made Fram's, it was some Allied corporation or something like that written on the box I saw.
