Skip White SBC 383 rotating assembly review
I thought I'd pass this along because I'm sure there are plenty of people wondering if these Skip White rotating assemblies that are on Ebay are a good deal.
First off, I needed a small block Chevy for a 51 Studebaker truck I picked up. I decided it would be a perfect candidate for a 383 and decided to try one of these rotating assemblies. This is going to be a STREET DRIVEN vehicle not raced. I wanted something that sounded mean, pulled hard, and was very streetable. The truck will have a 2004r transmission, 2000 stall converter, and 3.42 gears. I opted for the 24cc reverse dome pistons and I will be using Vortec heads (camshaft has yet to be determined).
So I stripped a virgin (never been taken apart or rebuilt) 1970 350 4 bolt main block and took it to my local machine shop to have it cleaned, checked for cracks, line bored, and to see what oversize the bore will clean up at. A week later they called me and said it cleaned up at .030 over. So I went on Ebay and ordered the rotating assembly. They gave me a delivery time of about 1 1/2 -2 weeks. It showed up a day short of 2 weeks. It came in two boxes (crank in a separate box) and everything was in good shape. I unboxed everything and it is all legit stuff with all the factory instructions. It also had a packing list and a balance sheet. I took one piston and the clearance specs to my machine shop for final cylinder to piston clearance.
Couple days later I got a call that the block was done. I picked up the block and did a mock up to see what the deck height was. Now Skip White advertises that he has these Wiseco pistons made special with a taller pin to piston top height so only around .010 needs to be taken off the deck to get the pistons at zero deck height. I found that the left side deck height was .004-.008 front to back and the right side was .007- .018 front to back. So I think I'm just going to use a .038 thick head gasket and not have it decked and call it good. I switched the highest with the lowest pistons and nothing changed so I know its in the deck.
This is just a heads up that these rotating assemblies are a good deal but might not work if your block has already been decked or decked to 9.00 like some machine shops do.
