It is a brand new restoration so everything is fresh. I'm going to have it on the ground today for a better drive. When I first fired it and at break in 2000 RPM all is good but then I revved it a bit higher and it shook. I figured I'd put it off and finish the car and address issues after completion. I took it around the block from the alignment shop to my trailer and was not pleased to say the least. I was skeptical about the engine when it arrived all the screw in block plugs water and oil were loose and a nut laying in the valley pan, not how I do things. I needed to step back blow some steam and get after it, I'm sure I'll get stuck finding the problem anyway.
