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
3310010I 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.
