Roller cam tools

My resto block is the best small block I ever bought. Barton wanted 5K I gave him a 68 340 cuda roller. And I am glad I did they were not available at that time. They were on back order. He had two I should have bought both. 59 degree R-3's are like hens teeth. They are just hard to find now.

An X block is a T/A block with thicker bores and High nickle content. also a good choice just watch out for core number. They are all 318 castings. This was so you could make a 355 with a stroker crank and a small bore light piston. Torque off the turn. Less reciprocating weight.

But as stated they could be bored 4.200 . So a small piston make the block very strong with less flex.
