I can only tell you what works for me......Im not a racer....i just want a reliable, stock appearing engine for an "occasional" street encounter, where sometimes, maximum effort is required. The engine is 0.030" over bore, running a Mellings HIGH VOLUME OIL PUMP, with standard spring. I use Clevite tri metal bearings (full groove upper and lower) @ 0.0025" so the rod bearings are oiled all the time and Clevite tri metal rod bearings @ 0.0025". I ise APR HARDWARE holding it together. The pistons are TRW forged 11.0:1 @ 0.005" (with full floating pins) clearance and Perfect Circle low tension rings (top moly faced). The rotating assembly is balanced. The cam is a Crane equilivant to the MOPAR 292° and 0.509" lift and Crane 1.6 ratio rocker arms. I use 7 gts. of Mobil One 10W-30 w/ a pint of ZDDP added; engine uses a windage tray. Cold oil pressure is: ~80 psi @ 2000 RPM; HOT oil pressure at 1200 RPM is ~60#; HOT oil pressure at 5000 RPM is ~ 75 psi. The lifter bores are UNBUSHED; block rocker arm oil feed hole is stock. I really don't care what anyone else does or how they build their engines.....I've built Ford (406, 427, 428, 460) and GM (350...Pontiac, Olds, Chevy) 427, 455) using the same criteria ......I'll stay with what works for me.......just my opinion of course.....
