I might have a big cam around 560-580 lift hyd roller. custom isky if I remember right. have the numbers but you would have to call to find out what duration. You can mick it to find lift. it went mid 10's na with the tfs heads I sold. how about 50.00 I'll let you even take it first since we have done business before to get it checked out and then you can pay me if you want it.
