(I am new to foxbodys FYI) So I bought this 87 mustang its got a cam a little machine work done and heads. I am confused about the following things.
- the timing is at 10BTDC (thought it should be like 12-14?)
- spark plugs are gapped at 0.60 (thought it should be 0.54?)
- he said to only run 91 octane in it (why would this matter if it isn't tuned?)
I have never seen this and im a little confused to why these are the way they are. Any ideas would be appreciated.
That spark plug gap seems excessive but when I tried .50-0.54 it ran like crap, same when I tried to bump the timing up slightly.
