Looking into lightening up the 429/460. I can't afford the aluminium heads, but do have an aluminium intake. I also have looked into water pumps. On ebay there are cheap noname brands I am quite suspicious of. I've looked at summit catalog and come across a few high flow ones between $140-$180.
Question high flow, and precautions like to high water pressure causing problems? Also looking for good oil pump and considering, changing out timing chain cover. Advice always apreciated.
