My buddy was an electrician foreman on big jobs and had those caps off his job sites.
Yes, the rust was everywhere but worse near heat, around the plug and exhaust valve.

Rods and pistons are in, heads are on, studs and guide plates are in.

My initial plan was to use this one as a spare, at this point I'm wondering if it will ever run long enough to even be that.

Glenn, I'm also moving the pickup. This is how it was, nearly 3/4.

Ran for parts today and made it to this point, tomorrow starts the search for the perfect lifter/restrictor combination.

DO NOT try to restrict the oil with the pushrods, that will not work. It must be done through the lifters.

What's the difference? seems like the end result would be the same.
