Well I finished tha cam swap from the flat comp 284 to the hyd roller xe282

and then i had some bugs ...man that popping thru the exhaust at 2500 had me stumped.........

After a few sleepless nights I figured it out...
Went to the garage turned out the lights and it was like a small lightening show...small crack in porclin on #1 plug..........

I took her out for a spin and I am impressed kinda pops a little about 5200 I am thinking it may need a little more fuel with the new cam???

But I can not reitterate check your plugs guys, the miss under load was killing me and you cold not see it during the day...

Now on to fine tune to get the higher RPM flutter out of it...
