The blocks are different years so there are a few minor details that have to be taken care of….first….the oil pick up is mounted and the oil routed thru a different spot. On the old block it had a shorter pickup tube and it mounted near Jim’s R finger….the new block’s pickup mount is near his L finger…so an extension had to be made. He couldn’t just use the middle mount because that part of the block hadn’t been bored out for the oil to run thru. He loves to be innovative…so he made the extension for it. Once that was done …fitted and sealed….he had to modify the oil pan windage tray. Here’s how it looked before he started.
And this is how it looks now. Most of the “fit” isn’t obvious..but if you look closely you can find them. Now it fits perfectly. This took the better part of the day. A little grinding and filing here and there…but only a little at a time until it was just right. Finally…..its back together. I’ve made this all sound rather simple…it wasn’t. It all had to be well thought out so there wouldn’t be any problems later.
