94GTPRO5.0

Ihave a 94 gt with just Flowmasters, Ford 9mm Plug wires, MSD Coil, plugs are gaped at .52 and Cold Air Induction,I was wanting to know whatshould Iset the timing at? Right now i have it a 15*, but when you get on it (wide open throtle), itwants to spike.So what should i set it at? Thanks.

Set timing with the pip out at 13-14. the gap on the plugs look a little to big.

12* is fine

I have tryed seting it at 15*/13*/6*/ and 0*,and it still spikes at full throtle.
My plug gap is .52,could the plugs be the problem. Plus before I started to Mess with the timing,it would backfire out of the intake? Anyanswers to any of this?

are you setting it BTDC, or ATDC?

and have you been pulling out the spout connector?

spike you meen pinging?mine would only allow 8* until i changed the 4 cats backpressure on the exhuast valve? sounds like you have another problem besides timing if its spitting out the intake or the diz. isnt on top dead center

well i'm sure the gap is actually .052" cuz no way could you get more than a 1/2 inch on it

but try going down to about .045" and see what happens ? what plugs ? DO NOT USE platinum

and +1 whaddya mean "spikes" ???? fuel pressure ? it will always spike under wot if yes
