84 Gt Timming

[sporty4680]

Hello All I Am New To This Site But Not To Mustangs. I Am On My Second Gt. My First Was An 83 Gt When I Was About 19 Now A Wife And Two Daughters Later I Just Bout A Mint 84 20th Anniversary Stang. The Car Was A Original And All Stock. I Just Put A Compcam 456 Lift 268 Diration Cam In It. Now I Am Trying To Get The Timming Right. The Stock Timming Is 10 Deg Btdc At 800 Rpm's With Vac. Hose Off. I Have Done The Stock Timming. I Have Also Done 14 Deg Btdc At 800 R's. The One Time I Had It A Little Less Then Stock It Seem To Run The Best. Not Sure Were To Put It. Also I Have Developed A Very Slight Miss At Crusin Speed Around 1000 To 2000 Rpm's. Can Anyone Help I Would Be Most Greatful.

possibly running lean, or getting weak on spark.

so when your advancing it , and making more power...you realize the weak condition?

i'd check fp first..w/ a guage, if you eliminate that factor...start w/ the coil and then try the distributor.

assuming all plugs, wires, cap, rotor are new.

you can gap the plugs way down to about .035 to see if that clears it up to id the problem as spark ...but that won't tell the culprit part, and i would do it after checking fuel pressure
