Re: Repair Pan case cracks around cam bushing?

Sadly cracks in that area are pretty common.
Is the iron bearing insert cracked as well?

Re: Gloss Black cylinder paint & clear over Alumiumn

I tend to agree with the others on clear over polished aluminum. It will have a cloudy look and once it chips, corrosion will creep under the clearcoat making a ugly spot you can't get to.

Far as...

Re: 80" Super Magnum motor build

good to see progress.

I have no manifolds on hand but guess making one will be easier than finding one that fits. Looks like yours is iron, the same can be found in aluminum that is easier to cut...

Re: Oil Pressure Gauge Problems

First, why did you put a gauge on it? Was it for looks or did it make you suspect low pressure because of strange un explained noises? Knowing how some gauges are, it's pretty hard to find one that...

Re: Oil Pressure Gauge Problems

Tell me more of what parts combination you have.
What weight oil are you running and was the pressure check done with cold or hot oil?

Re: 303 stainless suitable for axle

303 would machine and polish nice but 303 stainless is pretty soft.

Re: 80" Super Magnum motor build

Glad to hear your planning to check pressure at the rocker shafts when completed if only temporarily. I can see how you think pressure will be up enough because of the passage size. The small hole...

Re: 80" Super Magnum motor build

Scott
I think your setting your self up for an oiling problem.

Here is why I feel this way. On the U model engines that get a better than oem pump is a good thing. Your aftermarket pump may...

Re: 80" Super Magnum motor build

First... I like your project a lot.

Question about the oiling mods.

Why 360 degree oiling on the pinion?
How will you maintain oil pressure at the rockers when it's leaking through the pinion...

Re: Tranny Main seal shaft leak?

OK, the small seal that runs on the main shaft. that seal is pressed into what I call the main drive gear. The bore in the end the seal presses into quite often has burrs, a sharp edge and will...

Re: Tranny Main seal shaft leak?

To fix an oil leak, you must identify exactly where it's leaking from. Four speed transmissions seem to be the biggest leakers ever built. There are so many built in design flaws it's pretty hard to...
