My favorite set of covers were Donovan Engineering that came off John Wiebe's front engine top fuel car. The sticker from the Dallas nationals were still on them. I bought them from Billy Graham who ran them on his funny car. All to new for this thread. I ran 392's, sohc 427's, 426's in hemi and wedge, fe Fords, Boss 302's in my dragsters. The Donovan cover has the lovely lines that make a 392 look great.
