Time needed for 4.3 engine swap
Hey, shop guys, what is the typical amount of labor time needed to swap out a dying 4.3 V6 for a used 4.3 V6 in a 98 Blazer 4x4?

Re: Time needed for 4.3 engine swap

Re: Time needed for 4.3 engine swap
It depends on a lot of things. IT might take me a week or even 40 hrs.
A good r&r man can do it in a couple of hrs if everything is ready. I guess it depends what you include in the term "swap"

Re: Time needed for 4.3 engine swap
Basically if they were both the same 4.3 engine or needed little modification to work (if it was a 4.3 from the Astro or something). Replacement would come from a junkyard vehicle. Both completely stock, no power mods or upgraded parts or anything.
I have coolant in my engine from excessive driving with a gasket leak and i'd rather swap in an engine over driving it til it dies.

Re: Time needed for 4.3 engine swap
Oh, it is fixed. Was the typical intake manifold. After it was fixed my mechanic said the engine already had eaten a lot of coolant.

Re: Time needed for 4.3 engine swap
Depends on what exactly you are getting. My guide shows
15.9-18.75 Same engine (used) INCLUDES R & R OF COMPLETE ENGINE (WITH MANIFOLDS - COOLING & ELECTRICAL SYSTEMS INTACT) 22.3-23.5 For a long block & transfer parts. INCLUDES R & R OF MANIFOLDS AND ALL NECESSARY GASKETS - TIMING COVER - OIL PAN - CLUTCH - AND NEEDED ADJUSTMENTS ---NOTE--- IF YOU ARE NOT REPLACING GASKETS YOU SHOULD USE LABOR DESCRIPTION --> R & R ENGINE & TRANSFER PARTS 27.2-28.6 for short block & transfer parts. INCLUDES - R & R OF COMPLETE SHORT BLOCK ASSEMBLY - - - HOSES & BELTS - FUEL ASSEMBLIES - ELECTRICAL COMPONETS TUNE ENGINE AND MAKE ALL NECESSARY ADJUSTMENTS. I have found this guide to be pretty accurate for most things.
