Re: 1970 K20 Z62 Full Restoration
Here is the low mile 1970 K20 with 307 from BAT. This tube is 1970 only, as 1971-72 tubes have the rubber cap.

Right you are. Might be a late change. My March built Blazer has the steel cap, and the base of the tube is twist on.

After a thorough search, I have found the part number for the 1970 only K series with power brake booster oil filler tube. Per a June 1971 parts catalog, it is GM 3929746, and the part is stamped with this part number.
http://www.gmpartswiki.com/getpage?pageid=220375 https://67-72chevytrucks.com/vboard/...d.php?t=798420 Also used on big block medium duty trucks 1969-70 with 366 and air brakes.

Re: 1970 K20 Z62 Full Restoration
You have taught me something. Thanks! Bringing receipts! Nothing better than pics and part numbers. Love this group. Something else to chase.

Re: 1970 K20 Z62 Full Restoration
The fun is in the chase. Your right though. This board has so much education in it if you know where to look. I spend more time on here researching most evenings than working on my build.

Re: 1970 K20 Z62 Full Restoration
100%. I kinda thought I knew what I didn't know...cuz I'm actively chasing that! More that I don't know I don't know it turns out. I've already said it a couple of different ways in this thread. However good this truck turns out...it will be because of the help and generosity of information from the folks on this board.

Re: 1970 K20 Z62 Full Restoration
Ok. Back at it. So the engine got run in on the dyno which was (thankfully) uneventful. They did a couple of pulls on and she made 288/385. Which is more than the factory rating. But you need not worry about those gaudy numbers. I'll get her back under control with stock exhaust manifolds and a sweet factory single exhaust. Wouldn't want this horse to throw me.
She went from the machine shop straight to Eric's for paint prep. We got the clutch and pressure plate on. The entire rotating assembly was balanced prior to assembly including these pieces. Then the bell housing because it appears to me that the bell housing was on and "over sprayed" when the engine got painted. Clean up of this engine/drivetrain indicated as much. And Joe's low mileage K20 bellhousing has similar paint coverage Also had to scrounge up a vac line clip since this engine came from a K10 and had TCS (which had to be deleted on this K20).

Re: 1970 K20 Z62 Full Restoration
Hi temp primer and paint...
I should mention that Mike Cofield helped me find my date code correct water pump. Then he thankfully sussed it out when the "Dutchman" mistakenly sent my rebuilt water pump to him...that's a longer story than can be well told in one sentence. Needless to say Mike saved the day twice. Thanks Mike!

Re: 1970 K20 Z62 Full Restoration
Final paint this week and brought her home today. I threw a few quick pieces on just for fun. Unfortunately I've got a meeting out of town this weekend or I'd be fully dressing her out.

Re: 1970 K20 Z62 Full Restoration
Again, we will not bat 1.000 on bolt heads and OE hardware in this build, but a lot of effort has been made to use the bolts that came on it or would have come on it.
Honestly it was cool to see that Joe's 71 and this 70 engine had the exact same hardware arrangement on the water pump. Two "C"s on the right and an R/S/C on the left. Confirmed to me I had what came on it.

Re: 1970 K20 Z62 Full Restoration
The big win of the day was that thanks to Dave (DaHos), I hit big on a WTB in the parts section. He had one of the mysterious 1970 only oil fill tubes. No cap, but turns out there's a ton of them, NOS and pretty reasonably priced on eBay (considering what I've gotten conditioned to of late).
Thanks Dave!
