It is definitely cold natured that way. After it warms up, it runs pretty good. I still need to do some tweaking though. It doesn't have quite as much get up and go as the original Holley 1946. So far, gas mileage seems to be about the same. I am using the vacuum port at the base of the carb for distributor advance and the port from an early large bore (1.75") factory adapter for the PCV valve.
I have a new reproduction early 200 style exhaust manifold with the heat passage to install yet. I'll have to bend up a heat tube to the carb from this. The current exhaust manifold has the catalytic converter built in. It has a leak at the front port where the smog stuff is plumbed in. I think it might be partially clogged also.
I've timed it by RPM/vacuum, since it seems as the balancer ring has slipped. I have a new one that needs to be put on yet. Hopefully I can get this stuff done in 2 weeks, after I get back from church camp. I'll try to update then.

Well I found on Ebay a factory emission guide for 1979 and 1980 Fords. It covers every engine and every calibration along with the part #s. It is very sweet!
I was confused at how to find my Mustangs Vehicle Calibration, so I found out and scanned it in for all of you to see.
So looking at this
And now the new one ( Red78 ) Made for me - thanks!!
My Calibration is this (9-11A-RO) Date: 6-7-78
If you need to know what yours is and you have a 79-80 Ford let me know and I will help. I hope this helps you see how this works.
