LS3 Crate Engine or 6.0 build? 69 Chevelle

At the point where I need to decide to build a used 6.0 truck engine or pay up and get a LS3 crate engine? I'm leaning towards the crate engine less hassle no need for hp tuners etc. As always would be curious to hear from others who may have been down this road

Not real positive. I do remember G.M. has a crate engine that is for a ( PRE) 1973 or older G.M. car. It comes with the wiring and the tranny also I believe its around a 440 H.P. engine? A friend of mine stuck one in an early vette, 60s something?
Very easy install due to the fact it was designed to " GO IN " a pre 73- " A " body. Due some research, Then open your wallet! I think the complete engine package, Engine, Wiring, tranny, Harness, needed sensors, Etc. was around 10 grand, Not sure. All of the items you do not WANT or NEED are NOT on this pre 73 G.M. " Hot Rod " package.
Way to much " Engine Stuff " is available today. If you got the Cash!

I believe Robin is talking about the E-Rod system engines from GM. I saw some of these up in Charlotte not long ago. Robin's right, you get what you need and nothing you don't need. Here's a link to the engines:

No need for hp tuners. The easiest way to do an LS is terminator X. That’s the way I’m doing it. I am picking up a 6.2 short block.

I have not really been really up to date following trends but I have been hearing good things about Hollley's Terminator X lately. Is there an advantage to ie. cost savings or anything else as to just buying a package deal LS3 crate engine? Will you be that much ahead once you've pieced everything together?

At this point its a toss up between GM Performance's 430hp or 480hp LS3 crate engine. But this Terminator X has me curious I need to explore the pros cons, cost difference.

If you’re going with a crate motor just run the ECU for that motor that GM sells.

x2 probably no better system than the oem. Id charge up acrate before trusting a 200k mi engine, some have a little too much faith in them.
Youre still going to spend some cash either way may as well get new.

I think I'd agree but said new LS3 crate engine $10,000 + once installed vs used 6.0 LS with Holley Terminator X engine management $5000 possibly higher? decisions decisions

You can’t do an LS swap for much less than 5k if you’re willing to do more work and look for deals.
