88 GT n loven it....

I was wondering if theres any difference in the gasoline that we use forthe cars matter for example is there any performence difference between 87 and the 91 octane i was wondering because i am also gona advance the timing tomarrow im thinking if any of you guys know what would the best degree to set my timing i was thinking on 13 since that the most i can advance it for it to still be legal, also a readn a magazine that the perfecttiming for the 5.0 H.O engine would be 16 but that would not be street legal n california.... any sugestions apreciated since im gona do this tomarrow ....thanks

I'm pretty sure that the cops dont carry a timing light on them. Don't worry about whether it is street legal or not. Try 15 degrees with 91 octane.

the timing degree depends on your setup. are you all stock?? i deff wouldn't run any higher than 16. did you read that out of 50 mustang and superfords, i read that same article , it's in the jan 07 issue lol. if you bump the timing i'd run 93 octane.

every motor likes different timing. you just have to try what your motor likes.

Im not sure on which mag issue it was because i read it on one of my friends mags, although i do have a stock engineexcept for the C.A.I

step 1: put in the gas you are going to be using on a consistent basis
step 2: advance timing a degree
step 3: take the car around the block, hitting WOT at least once
step 4: if it doesnt ping, advance it 1 degree
step 5: repeat steps1 through 4 until it pings
step 6: back it off 1 degree

does it really make a noticable difference to advance the timing? besides not being able to use the lower octane gas

Varies for every car. Mine is at 18 and iv never had any problems.

thats better, and yes it can give noticeable gains. I gained22rwhp by raising the timing from 11 to 17 degrees.
