Let me know what kind of break in oil and regular oil you decide to use.
I'm worried about the "zinc issues" with flat tappet cams.

Will do. Definitely will use some type of additive, if not a dedicated zinc rich oil. Still researching break-in lube.

Did you get the 260hp,290hp or 330 hp?

[gringoloco]

260. The 290 is the same motor with an old school grind cam for $400 more. If I need a cam, I'll choose my own. Didn't look at the 330. Figured this was better than a questionable local rebuild for $1200...

The 260hp is a great deal. the burb has one it and and I am not sure of the mileage but it runs well. I will replace it with the same when it dies.

I used Brad Penn break in oil for initial start up and the first 500 miles. Then switched over to the 10w30. No problems and its been about 5000 miles.

I used lucal oil break in along with Valvoline VR-1 racing oil because of it's high zinc content. Had no issues with my BBC when I fired it.

Good to hear! I've seen lots of good press on these motors

I read that the VR1 formula had changed--not as much zinc now?

[mcbassin]

Another awesome addition to the family Chris. Too bad about the engine. I wondered why you were selling all your LS gear now I see you are going to GB. You have a lot going on bro. Subscribed

Man, you are not kidding. Such is life...

Parts are starting to trickle in--got my HEI dizzy and wires today, crate motor should be here tomorrow, along with a bunch of gaskets, plugs, etc...

Is removing ignition points considered ruining?

[gringoloco]

Brand new Jegs HEI unit

YES, there are some circles on these forums that are extremely displeased, but.....its your truck
Go for it

I know there are some guys on the Chevelle and Corvette boards that would cringe. It won't be numbers matching anymore after this weekend. I figure it's just a Blazer and not a super low mileage example. I will try to maintain the original look, for now, but it's a slippery slope

Yep, its only original once! Keeping the outside appearance is nice, but youre right, that slope has many cool parts strewn along the way

If you have the room, at least store the block

[gringoloco]

Hmmmmm, I do have a pretty nice sawzall

Crate motor and carb showed today. Also started stripping down the old slug in preparation for the swap. Rest of my parts should arrive tomorrow. Here we go!

let the fun begin!

[mcbassin]

Heck yeah! Nice looking engine. You may have said already is that a flat tappet motor? You got a game plan for the oil I'm sure. I have read about four different failures of non roller engines. Some were high buck engines too. Look forward to a video by Monday

Non-roller. Will use high zinc/zddp oil and cross my fingers! Probably won't be running by Monday, as I will clean and detail as I go. If it was just a simple motor swap, it would be done tomorrow, but I can't keep myself from doing it 'right'.
