Hi all,
This is my first post to this Mustang related forum. I'm going to try a few others as well, as I work to get my car back out on the road.
Here's the story. I have a 1967 Mustang C-code convertible. In the 1980's the engine died and it was replaced with a 1978 Mercury 302. It has a replacement "2150"-like 2bbl carburetor. Since I can never get the original engine back, my goal is to make the current one "better" with stock parts. Years ago the distributor failed so I now have a HiPo dual point centrifugal advance distributor. Sitting on the shelf ready to be put in (in winter) are an Autolite 4100 carb and a 289 HiPo 4bbl intake manifold. But that is for later.
Now, I need to replace my spark plugs. Originals were 18mm BF42 (BF32 in the HiPo). But the 1978 vintage 302 has 14mm ASF52 plugs. But what gap???? My 1967 shop manual clearly has 0.032-0.036" for the gap, but I cannot find the gap for the 1978 vintage engine anywhere. I looked through the 1978 shop manual Engine volume and it is not listed. Does anyone know where I can find the right gap for my engine? (And I can't tell you what engine I actually have, unless I can figure it out from the block casting numbers somehow).
Some guidance would be very much appreciated. Thanks in advance!
Dan
