I have an Aluminator in my garage right now. Got it last week. A bad Mofo is all I can say. I don't think you will deal with piston slap. It does still have production tolerences. It comes with ARP rod bolts, windage try, Cobra oil pump, and rear plate and main seal already installed. You will have to get Mach 1 tensioner guide arms and screw in dowels. I did order the 2v one.
Are those numbers for N/A or blower/turbo? If blower/turbo how much boost? Are you running stock cams? Stock intake manifold? I'm thinking about waiting for BBK's dual stage. What kind of heads are you using? I'm thinking about Patriot or Fox Lake. Thanks.
I've heard nothing but positive comments from the Fox Lake crowd. I hear mixed results from guys who have run the Patriot heads....so take that for what it's worth.
I would be interested to see your numbers with the Aluminator block when you install it. I have a P1-SC too but I'm thinking about upgrading to the D1-SC.
