Its still stock right now, I'm scared about the local machinists, the first 2 calls I made, I asked about experience with these motors, and they both said "they're all the same to me". So I'd rather find a stock rod and do the work myself. But, if I could find a reputable guy in southeast Michigan, I would like to have the crank cleaned up to match some new forged rods (K1?) and punch out the bores a little for some new pistons and have everything properly balanced and measured for clearance. When I toasted this motor, I got a couple degrees retard at the top of second, then let off (was around 12.0 a/f). I saw that the knock was still there after the pull at low rpm, and pulled over immediately and flat-bedded it back home. I have a brand new CPT-60 bb turbo from cotton's and it has somewhat of an inlet filter/restrictor (small metal screen). I have about 2 hours on the new turbo. The turbo shaft has no play and is very smooth, doesn't sound scratchy when I spin it but the oil in my motor had that metal sheen... should I send out the turbo for inspection or are bb turbo cartridges pretty durable?
