Almost begged me to build one last night and I told him I will give you an answer after I check on something today. Well I called him back with an answer this morning. I have one Keith Black block, one mega blocks, one 48 degree R block, a 59 degree R3 block, 3 stock 440 blocks, one 340 block, and 13 ( 360 blocks ). I turned down a 360 complete engine with a 727 bolted to it over the weekend for 50 dollars but may go back and grab it. After I told my friend the numbers of blocks I have he kinda understood but said he would still love to see what I could do with one. I guess if on fell in my lap it would be kinda fun.
