Quote: What front cover fits an R3 block? I have seen listings for regular small block covers & R3 block covers. Then covers for R3 block with standard water pumps & R3 blocks with Race water pumps. Anybody know what's the difference in these covers? I'm thinking of using this pump(Moroso 63565) . What cover will it fit? Thanks for your help.
The difference is tall block or short block covers so which deck height do you have... I'm sure the pump fits either cover.. the holes for the short deck look like a half moon in the cover
It's a 9.00 deck.
Ok... the cover will have the 1/2 moon openings in the 2 ports going into the block... MP part is P4876631 this is for the 9" and 9.20 deck with the standard pump and P4876632 for the same deck and front motor plate.... I use the 631 with a Meziere water pump with a motor plate and never have any issues(my pump has just the 2 ports that bolt on to the plate/block.. if your pump has the blades beyond the flat of the mount area you need the 631 cover
