Automotive? best for what purpose?... my favorites are the L88 427 Chevrolet, L72 427 & ZL1 427... Ford FE 427 side oiler & SOHC (Cammer), Ford 429 SCJ & Boss 9... Mopar 440 Magnum & 6 Brl/Pack, the 426 Hemi was great on the race track (not so much on the street)... i'm a Shiverlay guy, but i gotta' admit the Fords & Mopars were more durable, The FE won Lemans (with Chrysler Hemi connecting rods?), and the 426 Hemi Cleaned Up in NASCAR... and to beat the piss out of on the street, gimme' a 440 magnum or a 429 SCJ anyday!... "Gator Mcklusky" or "Kowalski" anyone ?...
