Runs very well except for this new high temp issue, if it even is an issue?
I think the culprit may be that the carbs are 4180's from an 84-85 Mustang GT and it is possible that I can't enrichen the idle enough for this system.
It was running on 54 mains out of the box with no issues.
Logic hit me, scared me and I upjetted to 63 primaries like the 427/428 2x4 set up uses.
I don't think there is a vacuum leak but with a monster like this it makes such a racket at idle it isn't noticeable.
It had a solid 17 inches at idle yesterday. Probability is low on that.
Obviously when you get to this point, the engine is like a race engine and what was ok 15 minutes ago isn't necessarily now.
This one has no oxygen sensor provision so I can't use that in diagnosis of the a/f ratio...but I'm thinkin'.
On the surface these things sound so simple. That is hardly the reality though. Remember, there is no such thing as a bolt on.
No life and death struggle on this. It will get right eventually.
On that plug, remember, that is the equivalent of a BF32. That isn't a hot plug at all.
I need more header temp info on this. 615 is actually on the high side of normal.
A colder plug should bring that down some?
I may have to dial out some initial advance too. Probably is set at about 16 right now. Advance affects the exhausts temps disproportionally too.
I am very sure the current crop of race cars have gone through this recently. I'm pretty isolated from them and some of them speak Martian like I do but not all?
