he's right on, L88 option, big block Chevy 427....the 435 hp was king...I haven't owned an L88, but did own a 327, 300 hp...with side pipe and hood...those 'vette's today are priceless...last one I saw sell at auction went over 100k...I would give my little XF for one of those...I think the black and red one is the 327 like I had, but the green sure was the color offered in the L88...
