Installed the electronic spark controlled distributor last night. I was quite happy when I found the plug wires were all long enough to reach the smaller diameter distributor cap with no issues.

Next thing on the list is to modify/fabricate a new throttle cable bracket. I think I'll be able to use part of an original bracket with a new support arm welded onto it which will then bolt to the side of the throttle body adapter plate. Hopefully one of us will have time to work on that tonight

It's going to be interesting trying to route the fuel feed and return lines from the back of throttle body. The coil will be in the way as is the manifold vacuum port. It's going to require some definite tube bending skills to get the routing just right!

Here's the original throttle cable bracket.

I cut the necessary section off and welded it to a plate that I fabricated to fit the side of the throttle body adapter.

One of the things I salvaged from the 345 was the cruise control cable backet that bolted onto top the original style of throttle cable bracket.

Here's the bracket loosely bolted into place to check fit and function.

On my test stand the throttle cable comes from the right side of the engine where once it's in the chassis the cable will be coming from the left side of the engine. It's really cluttered in this area with the throttle cable bracket, fuel lines, coil and distributor. The fuel lines are going to have to be routed to the right side of the distributor in order to make things work.

I'm going to have to do something on the test stand as I don't want the throttle cable laying across the top of the distributor!

The area between the throttle body and distributor is definitely a crowded area. Here's a couple of pictures of the fuel lines I bent to fit from the throttle body down to the back side of the engine. I'll have to fabricate some sort of support bracket for the lines where they turn to go down past the transmission.

A couple of pictures showing the throttle and MAP sensor bracket. I ended up combining the two and I think it gave a much cleaner arrangement in doing so. I had thought about mounting the MAP sensor to the air plenum but didn't want to deal with drilling and tapping holes in the plenum and the fit wouldn't have been quite right. I'm quite happy with how it came out

I should have the coil mounting bracket done later today which would complete mounting all of the engine related components that need to be installed for the TBI system.


I'm also just about done assembling the fuel feed system for the TBI. Attached to the plywood panel are all the components for the fuel feed system. I didn't tie in the fuel filter for the low pressure pump as I haven't received the correct fittings yet. In the mean time I just added an inline fuel filter as a temporary measure. I also added a fuel filter after the high pressure pump. I'm not sure if it should go before or after the pump and since I only had a filter for the larger 3/8" line on hand I opted for the latter

Next step is to wire the fuel pumps, install the TBI harness and make all the necessary electrical connections to power it up. I'm thinking maybe this coming weekend I'll be able to try running the engine with the TBI system. Fingers crossed!

Cool, Brad, making great progress. I would put the fuel filter before the high pressure pump. But I really don't know if that has an impact on proper pressure regulation?

I'm not sure either. I'll do some research this week to see what's considered best practice.

It's amazing how much time it took to fabricate the throttle cable bracket, MAP sensor bracket and the coil bracket. I probably have 2 days wrapped up in all the nit picky little details in trying to get those three brackets to fit and work with each other

All that's left now is to install the TBI harness and make the appropriate external connections for ground and power. That will have to wait until Tuesday or Wednesday due to the need to mow tomorrow after work.

Yeah, I was considering doing that but didn't want to make that decision until the engine is install in the chassis.

Not sure why some PO decided it was important to let the passenger know that the Argosy was protected by WD40 but they did

I can't say that the WD40 did much good as there was still a good bit of rust to deal with.

Somehow the Engineering Flowchart never seemed more appropriate.

I believe the PO also had issues with movement as there were plenty of duct tape remnants found as well!
