["Puddles the Pontiac"]

Geoff, i had that happen as well. they are comp lifters that came with the cam. with break in lube (from comp). i run Rotella T oil. and checked the lift to make sure a lobe didnt get wiped out. the miss itself is irregular, but its constantly happening. i also noticed the miss with the timing lights light. leading me to think it is electrical. btw, i will be using a different light to set timing. thank you for the responses so far.
