Since i'm already tearing apart the lower part of my engine I thought I might as well do things like timing chain, oil pump etc... and I was thinking of going with a high volume oil pump, I can only see advantages to doing this, anyone think of a reason not to? BTW i have a '69 302 2bbl. One thing I can think of is the highvolume might make the leaks more pronounced, but hopefully i'll be taking care of all of those this weekend with the new rear main/front main, oil pan, valve cover...
