Clay, nice job restoring the inner heating assembly. It looks brand new.

The engine is running!
A few weeks ago I was able to get the engine to fire up and run long enough to break in the cam, but I had a few issues. In addition to some oil and coolant leaks there was a timing and vacuum issue that just wouldn’t allow the motor to run right. It was running hot and just seemed to dog quite a bit. I wasn’t really sure if I had a timing issue, or a fuel issue or what, so I opted to take the carburetor and distributor down to an old school place out here in Phoenix called “Carburetor’s Unlimited”. The owner, Bruce, identified a few issues right off the bat and recommended a recurve on the distributor along with a Pertronix ignition setup and coil. He also went ahead and redid the carburetor and even plated it the correct gold-ish color! I got it all reinstalled and she fired right up and was purring like a kitten! Per Bruce’s recommendation, we set the initial timing to 8* BTDC and the old 327 is humming along nicely! I still need to do final adjustments and will get the timing dialed in more after the truck can move under it’s own power.

Here is a quick video of her running!

That is great to have a place like that close by.

Saw your video on YouTube before I saw your post here. When I watched the video I thought the fan doesn't stick out of the shroud very far. Might be far enough, but I know you usually want the fan about half in and about half out of the shroud. Hopefully just something to be mindful of and you don't have cooling problems....

Hi Jason!

Honestly, I have no idea how far it needed to be in. LOL

I just put it on the way it came off. I was actually thinking about putting a clutch fan on it anyway. We will see what happens and if it overheats I will figure something out.

Saw in the video, it looked like you got your brake lines sorted out.

For your exhaust did you use the factory type muffler hanger? It's the flat metal strap with the 'eye' bolt and the 'eye' hook? When I redid mine I think I ended up with an extra set...

Hi Jason, yeah I got the brake lines all figured out finally. I sent mine back to Inline Tube and they replicated them. They did a pretty good job. It all matches up. I am am hoping to have the brakes completed and working in the next week or two.

I was able to reuse the factory muffler hanger except for the flat strap piece itself. That was too far gone to salvage. The bracket itself was able to be cleaned up and reused. The strap was a standard 1950's Chevy muffler strap that I ordered from Napa.

Here is a link to the strap I used:

I had that guy rebuild a Qjet for my K5 almost 20 years ago. He is definitely a carb guru.

Engine sounds great! Good update

Thanks Scott! Yeah, Bruce definitely knows his craft for sure. He is a walking encyclopedia of carb and dizzy facts!
