looking into a few more parts as i keep working on my engine. ive tried searching on here and on google without much luck. I know mummert has the aluminum front timing covers, but is there an aluminum water pump that works with these engines? Does ybloke still make and sell his 4-71 supercharger intake, or another manufacturer in the us? If not are there any hints or tips in how to build one. I have the tools and ability, but not the experience on how it should be built, where to runner design, plenum design, should it be shifted forward or backwards. I know a lot of these details may not really matter but seeing if i can get some tips before i go down a rabbit hole. 
Thanks, seth

Y-Blokes 4-71 intake is still available and is an excellent piece of work. The water pumps are no longer being made. They were too difficult to cast and had some flow problems. 

Y's guys rule!
