You know for me it has nothing to do with being a purist. It has EVERYTHING to do with yet another run of GM small blocks in hot rods.
When I go to a cruise in I want to see something different. A Caddy engine in a hot rod, maybe an old Nail Head Buick, Olds engine, flat head. How 'bout a Hemi? A FORD engine of any kind, thats fairly rare as well.
You want reliable, good mpg, easy to drive? Cut to the chase and buy the Camry.
