Who's running 87 octane in their mainly stock foxes w/ good success? Been running 89 in my wife's but wanna see if 87 will fit the bill. Timing is bumped to 12 or 14, can't remember where I set it at. Lemmie know.

Thanks

when I first bought my cobra, I ran it on 87 octane

you might want to change the timing back to 10 stock if u do go to use 87

IF IT DON'T PING YOU'LL BE FINE Bernie......my 92 carbed set up ocassionally I run 87..mostly 89 though but with 87 it never pinged and it has stock bottom end and e7 heads timing is at 13 on it

I see alot of guys on here running 87 oct w timing at 12 and 14 b/c there in cooler climates. I know elevation has something to do with it too. I got my car in the winter and it was fine on 87...til it got 112* and that when I learned about "pinging".

I ran my stock fox with 87 for about a year or so with no problems
