I was wondering if anyone knows how far below oil pan to block seam should full line on dipstick be. I have 4 old Mopars, 71 New Yorker with 440, 67 Newport with a 383, 64 Polara with a 68 440, and a 63 Dodge 440 with a 426 wedge head. The New Yorker, Newport and Polara all have identical length...
