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
