Thanks guys for helping me decifer what the 1969 engine was on yesterdays post. I didn't think it was a Corvette motor. Let me tell the rest of the story, I didn't want to complicate my question.Although I own a Topflite big block, the car I also own is a 1970 Iso Grifo Targa, it is often refered to as an Italian Coach works Corvette. BUT! The 327cu in 300 that I refered to would have been correct in a 70 Grifo, but a 350 cu was an option. This car blew its 327 back in 89, and he installed the current 350. At least now I know what it is for part specifying. It has Corvette valve covers, and air cleaner, and has the look. This is a great sight for technical info, I appreciate everyones help, and I'll get back to official "Corvette"" business. Thanks Don Meluzio
