You might want to take a look at SCAT as well they have real nice stuff right out of the box at the same price point. IC825 Icon pistons with 7.100 rod and 4.250 crank.

Thanks, I will. Here is what Muscle Motors sent me, it's what included in their 512 kit(found in their Killer Krate):
4.250 Stroke/4340 Steel/ Micropolished/2.200 Journal Crank (RPM or K1)

7.100 Length/4340 Steel/H-Beam/2.200 Journal/.990 Bushed Pin End/ARP 2000 Fastener/Size & Pinfit(RPM)
4.350,4.360 or 4.375 Bore/ Forged/ Dish or Flatop Piston/.990 Pin/1/16,1/16,3/16 Ring Stack(Icon)
Speed Pro Plasma Moly File to Fit Ring Set 1/16,1/16,3,16 Ring Stack
M77 Chamfered Rod Bearings
Federal Mogul Chamfered Main Bearings
Competiton Actual Component Balancing.(Not book weight balancing)

I like this the best so far, their pistons are -26.7cc giving me a CR of 10:1 and Dynamic CR of 8.4:1. That should be good for 91 octane right? I think I read a Dynamic CR of 8.3 would run 89 octane so .1 should run 91 no problem?
