This seems to be a pretty common question but Im afraid I have to ask it again. I have found a few numbers on my block and other places that I cant find anywhere online or in books if anybody could tell me what Im looking at Ill be forever grateful.
Best I can tell (using a mirror and flashlight) the number on the block behind the drivers side head is
3310010
I have several numbers in the intake but the one that looks the most like others Ive saw is 3818803, also on the intake is "H 21 7" and GMI with a capitol "T" under it.
Stamped front of the passenger head is 1020CUB
Any insight would be killer! thanks in advance.
