Ok, before somebody asks, yes I did try to do a search and found HOW to decode an engine block, but not really where these numbers are. The numbers I located dont seem to match the ones found and listed in other posts.
The bottom line is I need to research the block, mainly the year, in order to know what plugs I need for it. Right? I know the gap can be figured later. It is a 454 and Ill try to describe the numbers I found and where they are.
On the top of the block at the middle and just back of where the timing chain is stamped T0117TRU (Im assuming the 11 are 1's and not I's). Looking at the front of block as a ref to right and left there is a large casted GM T12 at the rear of the block at the top where the bellhousing meets. Just below that is 361959 casted further to the right.
Now somebody mentioned the head numbers so Ill include them also. F1171 is casted on the top left. GM 10T is next, the letters PASS in the middle and 3993820 on the right.
So, am I looking at the right numbers or are the correct ones somewhers else on the blcok. Oh, this is a swap so the vin wont be a help right?
