Big bore Open deck sleeves

I posted these to my facebook account, but wanted to share here. These turned out great, even though the lead time was quite long. Capable of 4.125 bore. Minimal block machining required to fit the larger OD sleeve.

WOW...you told me about that. Could be a really big engine in combination with a 4.125 crankshaft!
