Hemi Swapping a perfectly good 70 Duster
When @HemiDenny originally designed his G3 hemi mounts, he used the Milodon oil pan. The Holley cast pan is a little deeper in the front and back and the sump is also in a slightly different position. Denny couldn't say with 100% certainty that the Holley pan would work without some "adjustments" to something. Here are some photos of the clearances for those using this combination of parts. Note, I have the engine all the way forward since it was too close to the firewall for my liking in the rearward position. Pushing the engine back would provide slightly more clearance. Nothing is touching, so I'm good with how it is. Denny primitively figured out a solution if these parts contacted one another.
I'm slowing knocking things out. I had limited time this past weekend to get things done. Headers are in and tight. There's no way I would have wanted to tighten headers with a stock K. Pretty sure I'd let someone kick me right in the nuts before I'd choose to do that! My modified Z-bar is installed and clears everything beautifully. I found my old starter power wire had become a victim of excessive heat. I'm glad I found that. I made a new one and put some heat insulating loom on it even thought its no where near these headers. Of course the solenoid wire was too short, so that had to be remediated.
More to come as I knock things out!
