New combination: “Frankenstein” - 526” Mega Block - K1 4.25 with 2.2 Chevy journal (Mopar width) (reusing the main bearings, they looked perfect) - Eagle 7.100 rods (used but only had 69 passes and I know the motor they came out of, also reusing the bearings) - 4.440 Diamond Pistons (standard ring pack, 1/16, 1/16, 3/16) - 12.6 to 1 compression - Fel-Pro 1039 .051 composite head gasket - Lunati Roller Cam .678/.678 lift, 278/286 duration @.050, 112 Lob Sep, 108 Centerline (~.030 more lift, 6 degrees more duration on both int & exh, same Lobe Sep and Centerline) (This was a damaged Lunati roller cam that I picked up in 2012 at Monster Mopar for $25 and had it reground using 53714LUN specs but keeping LS/IC) - PAC 1325-16 Springs – 314 Seat and 752 open pressure (644lbs spring rate, installing at 1.910, bind at 1.150) - New Valves but no porting, just standard valve job - Harland Sharp 1.6 rocker (not mismatched 6 - 1.5 and 2 - 1.6 intake rockers) - Milodon 31161 dragster/chassis pan, dual line swinging pick up, Muscle Motor Oil Pump cover, Milodon 21815 oil Pump with external fitting for 2nd pick-up line - Dynamic 9” converter sent in to tighten it up on the top end but leave the stall around 5,500, want to shift at 6,800 and go through 1/4 at 7,000 – 7,200.
Essentially 26 more cubic inches, a little more stroke & bore, a little more compression, a little more cam(roller vs solid), better oiling system and a little tighter converter.
