I bought a dressed 408 from Blueprint in 2008? I have abused it to no end and it has performed fine. I’m still running the block/rods/crank at this time. When I pulled it apart to change pistons to bump compression the bores were still straight and round. The crank was still straight. Two little things that I ran into. It came with a Kevko oil pan which I really like, is only about 3/4” lower than the k frame, but The drain for the oil located outside the baffled sump area. So when you change oil it holds over a quart of oil that doesn’t drain. I email Kevko about it, no response. I mean it is such an easy fix. In the end I just installed another drain plug in the sump area. Also a week after I got it the dip stick missed the hole through the baffle in the pan and got snapped off by the crank. Not a big issue, but a bit bigger hole would be nice. Maybe they would listen to Jonny Mac.
