Those are nice rigs

We have battled fowling and had tune up's done x2, spider injection harness replaced, as well as other things I can't identify, or understand. A friend and me did the water pump. Shop did a gasket of some sort? After the spider harness, it has ran pretty good for about a year, and thought it was good to go. Now the #5 misfire is the problem. I have spent dang near enough on this engine the last 3-4 years to have a huge dent in the cost of a new motor. I change the oil and do very light maintenance on all our vehicles. A motor swap is light years outta my comfort zone. I have shot trap with the mechanic since we were kids, and is a straight shooter at the range and with his business. I sure do appreciate all the comments on here as I value the opinions of the folks on here as well...Doing my best to make an informed decision. We shall see what they find!

(That engine has 8 individual injectors, not the spider injector thing)

It doesn't make a lot of financial sense to put crap tons of money into new heads on an engine that has 150k miles on it.

Its Central SFI system which people call the spider which is a unit,  still all located under the upper intake, silly GM..........

If you were one year newer, I知 selling a Suburban with a great motor and ok rest of it that would make a perfect pair.

I thought the spider harness had new injectors on it?

You can buy them both ways, atleast that part would be newer for the replacement engine if you decide to go that route

[jackelope]

Not sure why I thought they were individual injectors. I thought the older 4.3's had that style but not the V8's. Ah well...wrong again.

[jackelope]

I've been dwelling on this for no reason at all, but I remember doing single injectors on these things in the past. Maybe because it was warranty work and maybe because it was 20 years ago at the Chevy dealer

I hear ya on how stuff runs together!

I知 very interested in this as I知 currently dealing with the exact same dilemma. I have a 95 suburban at 225k miles. The rest of the truck is solid, I知 the original owner and have the truck rigged up perfectly for my needs.

I was told I have a blown intake valve and am getting no compression on cylinder 5. I知 leaning towards dropping in a crate motor; was quoted $5600 for a Jasper with a 3yr/100k mile warranty. Not sure how long I should shop around, or if that痴 a reasonable quote.

That's a brand new, not remanufactured engine shipped to your door with a warranty.

$5600 for an installed reman seems a little high to me.

Me too. That's a pretty easy swap.

[jackelope]

Almost every engine I致e ever sold has been remanufactured.  Probably several dozen.  A replacement 5.4 v8 in an F150 from the dealer is close to $8k out the door installed. 3 year unlimited miles full parts and labor warranty for comparison sake. Granted labor is probably a little more expensive where I知 at but the labor time guide probably calls for 16-20 hours to replace an engine.  I don稚 think any shop is $100 an hour anymore, even independents so at $120 an hour you池e looking at over $2k in labor.  There will always be a $200-300 in extras like a belt, fluids, random stuff etc. $5600 seems pretty reasonable to me. Just understand with a Jasper engine, all of the labor will not be covered unless you pay extra for it and if it does have a significant issue, there will be down time with no coverage for alternate transportation.
