48 degree Block

No deep pockets here, just thought a R block would be better for racing. The 340 I built for racing, has 2 sleeves in it. Got the block for free, when I purchased some other parts. So if it blows up, I got very little in the block. I just seem to see more 48 degree blocks for sale , and more low deck ones too. My supply of factory blocks is very limited, so was looking to the future.
