72 Suburban Making it mine

[bowtieguy79]

Got the 402 apart, found a few things that didn't make me to warm and fuzzy..

Cylinder 7 has a little issue. This explains the white milky junk that came out of the water passages... it had to be block sealer.



Also found that the flaking cam was slowly taking out my Number 2 and 3 rod bearings and third main bearing...



Rod number 3



The crank lived, it should polish out. The pistons and rings all looked great, very even wear on the top rings, nothing stood out as an issue. The thrust and anti thrust on the pistons are clean and had very little contact with the cyl walls. For a 43 year old engine, it was in great shape... besides the nasty casting flaw...


So I sent a mass text out to my Car Guy buds. I found a numbers matching 402... I got it home last night and on the stand. Pulled one head and its a stock bore and I can see cross hatch. Crossing my fingers this block works out.

It is funny.... I can almost feel the black hole of the LS world sucking me in.....
