B&m 420, 6:71 or 8:71?
Mild 454 .030 over. 088 heads. Good pistons rods etc. have found some good deals on all 3 of these blower kits. The 420's with chillers. Which would be the better setup? I trust the people who have them and have a good idea which one I'm going wit just curious for others input

Any one of them would work just fine. Innercooler is added safety but I have read the superchiller type cooler corrodes in saltwater. Stock merc stuff was hard anodized blower/intake. I think TBS is hard anodized as well. I have a 871 littlefield and whipple cooler. The 420 and 671 are about the same size the 871 is a little larger.
