Magnum swapping the 72 Scamp!

A couple comments on the oil pickup.

Purge the tube with a constant argon flow to avoid the ( sugar) inside. And, it must be clean. DO NOT USE BRAKE CLEANER TO DEGREASE! Argon plus BRAKE cleaner plus heat equals deadly gas that will kill you. Also, the sugar is very hard, a small speck of that slag will cause damage. Good you got that out of the oil system.

You may want to reconsider using that main bearing bolt you welded on? I wouldn't use it. I'd find a different way to support the tube.

That bolt has a specific tensile strength, temper, elasticity and yield point, all of that was changed by the heat. Not a chance in hell I'd use it!

I'd have way less problem with a tab under the main cap bolt than a compromised bolt.

That's just my opinion. I like what you're putting together though, nice car.
