Cruise Seems Lean

@71GSSDemon Why would you want to put primary blocks on the secondary side of this setup?
Honestly. I think you need to focus on one thing at a time. Get a non-leaking radiator in there and a fresh set of plugs. See how it runs. Then go from there.

Edit...I changed the wording in the previous post to be more clear, that is what he did. Not that I ordered parts.

While waiting for the parts you can go back and read some of the stuff posted earlier. The answers about to most of what you're asking is there. As Tuner would say, some assembly required.

Right. Unless you want or need 4 corner idle you would just need two blocks. I’m with Mattax. Work on the heating issues first. Then you can start looking at a power valve on the primary side.

Sorry guys, I didn't mean that I was doing that conversion at all. It was mentioned here, to explore power valves. My front blocks do not allow this, so I asked a carb guy. That is what HE is running. That is why I put it in bold and italics, that's all. My plan....I got new plugs and installed them. I am working on a new alternator bracket that will lower it, thus allowing the belt to wrap the water pump further, waiting for the radiator, reading the previous posts and others, and looking everything over. This is how I found the vacuum advance hose had split on the trip. That vacuum leak and loss of vacuum advance didn't help. I am listening and trying what you guys are saying. Thank you again.

Edit. I changed the wording in the previous post to make more sense. That was a quote from Andy on how he got power valves in his 660s. Not me
