flat on my face with fireballs blowing out the back...

[KobraKarl]

Hi guys ..long time no talk.....been doing the divorce thing..

.i AM keeping the Cobra.

any way...I am having some performance trouble with the 427..after running for 15 or 20 minutes it will start popping and missing at 3500 rpm or so.....a bit later it will almost quit running ,and any aggressive use of the throttle will cause a complete "faceplant " and enormous firey explosions out the pipes.

The only other symptom is a general sluggishness to the overall performance. and some increased crackle at throttle letoff

initial timing is 14* at idle.

Thanks in advance for any help, KK
