I would agree that he should check the air cleaner base height, but he talking about a 340 Six Barrel conversion.

The factory never made a 383-400 Six Barrel air cleaner base plate so the different height of a low deck big block base plate isn't a problem in his case.

Kayse can't keep up at all now. lol
