How well does that '67 radiator fit?
We have a Campion aluminum unit that is "supposed" to be for a '66 A body and it has no where near that much room!!
May want to call them.
That radiator shows for '67 up dart, not '66.
Early A's have a smaller engine compartment.
Not saying it won't fit. But mods may be needed.
I would get a tape measure and the dimensions from the site at least.
Used 360 I bought with an unknown cam.
Turned out to be more of a "race" motor than I thought it was.
Ported heads, Crane Blazer cam, 273 rockers and a manual choke Thermoquad.
I set it at 10 degrees and after its first road test it boiled over as soon as I shut it off.
Tried all that you have...
timing is retarded. specs are like 10-12 degrees. back in the day we used to "turn them all the way up" or, as far as the slot in the adjustment would allow.
