I need to get a new water pump for my '69 340 and I have a question for y'all. I'd like to get a high volume aluminum pump, the ones I have found (Milodon, Carter) are for '70-'90 small blocks and some Mopar #P5249559 and others are for SB Mopar but aren't year specific. I'd like to buy the right one the first time. Suggestions? Who's using what? Thanks!
