Which engine would you want in your 80s k5 blazer?

Any reputable shop will include warranties and would let you come see how they are built. They will provide parts lists and be confident enough in what they are using to provide manufacturers of parts.

New pistons means far less than new mahle cast pistons.

Or whatever. Realize that you do get what you pay for. There are ways to slap a runner together for cheap, and there are ways to spend a little extra to get some longevity too.

Talk to them, go see them. Ask what parts they are using. Ask what parts get serviced and reused.
 
It seems like these are my 3 main choices if swapping a bad engine in 1983 k5 blazer. A bit torn.
My intention is to have a very dependable cruiser I can enjoy for rest of life. I'm 46.

Anyone have a good or bad experience going down one of the roads below? I'm willing to pay more if value is there. I'm just not an expert with engines.

option 1 craigslist rebuilt 350: https://dallas.craigslist.org/ftw/pts/d/crowley-sbc-chevy-engines-performance/7043260961.html

option 2 blueprint crate engine https://blueprintengines.com/produc...ck-gm-dressed-longblock-carburetor-bp3501ctc1

option 3 GM 350 HO Deluxe 330HP https://www.gmperformancemotor.com/parts/19210008.html

Do you have to meet an emissions requirement?
 
Well I like the roller cam in the blueprint. Not a fan of bypereutectic pistons though.

The gm is nice because everything is brand new but it has a flat tappet cam

If you were buying this truck which engine would you want to see under the hood?
 
What’s your budget?

cuz I’d like more engine. But it’s not my wallet
 
First, let's back up a bit. There is likely several reputable engine houses in your area than can rebuild what you have, or start from scratch with a TBI era block that will accept a hydraulic roller cam.

Find out the good shops, and do the leg work like @Justin V suggested. Tell them your budget and use and see what answers you get
 
I will never go older than an L83 swap after @Fastereddie hooked up my 77. It's a little more up front outlay but the return has been awesome. Just a thought.
 
Tons of things to consider...

If 4K is your budget, does that mean everything? Or just engine price?

You'll possibly need hoses, plugs, water pump, t-stat, wires, cap and rotor(or whole dizzy), exhaust, intake, carb or injection, fuel pump, fuel hoses, filters, fluids, a second oil change, break in additives, radiator, gauge senders, etc

Need to look at the whole picture before you decide on an engine.
