I would like to caution anyone looking to build one....know your **** before you dive in. It may seem simple, but it's not. You can pretty much consider any of these engines to be one off prototypes. R9=R9....no way!
These things changed almost daily. If you do not have parts from the same batch...you have scrap metal. There's shops all over with 90% complete RAW5789 engines. From day one it was an issue. From DLMs, 358 Mods, trucks, Ect, it didn't matter. Piles of mismatched parts, and no support or direction. I personally know of two occasions where Mopar sponsored dirt cars were running GM engines. They simply could not put together a running engine with the parts available to them. Truthfully I'm surprised that the Nascar guys did as well as they did. They must've been scrambling too waiting for parts. The timing cover always seemed to be the missing link. I didn't run them, but was surrounded by them in the pits.
