Customer sends me a speedmaster 9.5 aluminum block, ya know availability and all so on and so forth. Sure I will take a look, he was as blind as I was with these. Let's check it out. First off, pretty rough finishing, especially this china wall thing they got going on, see pics. Very thin lifter valley deck, which would coincide with the bracing in the lifter valley. .175 thick in the lifter valley.
Comes with chinese main studs, so those are out. It's pretty standard stuff, except for the main caps. Shockingly the main caps are not doweled at all and one can imagine the mains moving all over the place under extreme load. Haven't even begun to checking the cam tunnel, the lifter bore angle and locations etc. Suffice to say, customer is now sending a bill Mitchell aluminum block. This was an experiment that sht the bed before we got going.
For someone looking to make 700-800, maybe but I would recommend to stay far away.
