Little bit confused.... Bought what I thought was Del sol b16 block however when I looked closer, the part code on the bottow of the block, pistons, and caps, is Pr-3 which tells me that its from an older crx. Whats confusing me though is the block badge says "B16A2". My first thought was that the guy just etched it in but its too perfect for that to have happened. Anyone know if the PR3 part code is used anywhere else?
