Jimi, thanks, the Crankshaft is a Performance Engine Products,(PEP), brand 4340 Forged Steel, Non-Twist, Nitrite Hardened, full radius on all journals, chamfered oil feed holes, 6-bolt rear flange, machined for pilot bearing, full race balance. The rods are made by Carrilo which are 4340 steel, bronze bushed for floating pins, double ribbed at the big end for increased strength, H-Beam design, ARP 2000 fasteners. The Pistons are made by Keith Black and are billet 2618 alloy, 1/16 comp rings and 3/16 oil ring, forced pin oilers, ribbed and accumulator grroved to prevent ring flutter at higher rpm's, alloyed with a proprietary alloy that allows a tighter piston to cylinder wall clearnace. The piston pins are chrome-moly steel included with the pistons. The rings will be Childs & Ackerly ductile iron/plasma moly file fit, thats what the finish is for anyway and the pistons have already been fitted to the cylinder bores and numbered. Here are somemore pics. To answer your 2nd question here is some intersting info on E-85 and the pros and cons of utilizing it as a fuel in your engine. The carb will need a alcohol resistant float and gaskets, the plugs may need to change to a colder range, the fuel sock in the gastank pickup may have to be changed maybe not. It depends on what it's constructed of. Rubber hose may have to be changed to a alcohol fuel type. Not difficult, but you will consume more E-85 to gasoline because it's not as thermally efficient. But it has a much higher Octane than our unleaded premium E-85=105 UP=91-94 so you can run a much higher ratio, as high as 12:1 or maybe higher depending on the cylinder head design, open chambered older heads may not use as high as a modern small chambered closed design with lots of swirl and turbulence designed in to them.
