More Progress
Decided to take a break from the car and assemble the short block. Crower billet 4.25 stroke fully couterweighted crankshaft, Oliver 6.800 rods with ARP 2000 bolts and of course Ross Custom turbo pistons. 4.157 bore, 1.2 mm top, 1.2 mm second and 3.0 mm oil ring set. First step was filing ring gaps. .032 top and second for medium boost. Used a BOP one piece rear main seal. The camshaft in the block was just for checking fitment after slamming in the cam bearings. I'm working with Herb from Luhn Performance on a LS firing order hydraulic roller for this motor. The Edelbrock heads should be ready in the next few weeks from SD Performance. So we'll pick up then on engine final assembly.
