Title: Loader grate
Post by: Santee_Native on July 09, 2012, 03:57:42 PM: Thinking about installing one in my 1986 21' open bow bahner with a stock 454. Been doing a lot of reading about them and from what I can figure out its eaither gonna hurt my performance or benifit me. The pump is out and being rebuilt right now so I would like to do it now if it's gonna benifit me. The pump is being rebuilt with a A impeller detailed. What do you pros think I should do go for it or not?

If you are not going to tap the intake then a 5/16 is what you need. I you are going to tap the intake then your tap will tell you what size to drill. My chart says it would be an F drill.
