Right on, Kool. Sounds like one of those things where if you're going to do it, you have to do it all the way because halfway is worse than not even starting.
But this is great! For years I've been hoping somebody would do a conversion like this. (The 350/350TH upgrades are great, but ...) So PLEASE take lots of pictures as you go and write up as you go. This is a fascinating (for me, anyway) thought process you are going through as I am starting to think possibly that I might cease work on my '49 and convert it to diesel.... A lot of other guys around here are too.
You are the first that I know of to actually start the project (and tell us about it) so please share your data! Sounds like an awesome Tech Tip/Feature article in the making.
Thanks,
John
