It runs real good, almost no blow by. Anyway,.. my question is; is there any benefit in going to synthet...

Oops... Rear axle shaft broke clean at the bearing, probably due to the latter failing. By chance, car was slowing down on a small residential street. No damage to the body, but brake shoes and springs, lines, etc. are toast.

Working on a 63....it has a 350 short block....with original 283 top end... We're trying to restore correct 63 pulley geometry. There is spacer/shim on the end of the water pump...under pulley....which appears to be putting the w/p pulley just slightly out of alignment...with the crank pulley......

There's been discussion on this in the past. When GM put a 4 speed in a car, it looks like the worker on the assembly line cut the hole in the floor with a torch. I took this picture yesterday in a wrecking yard. It's a 64 Grand Prix that is most certainly a factory 4 speed car.

The '61 was not originally equipped with an oil filter. At some point an aftermarket one was fitted. There is seems to debate as if these are useful or not. It is however in the way of brake conversion. I could move it or remove it. The existing lines would not stretch to a new location. They were brittle an...
