Crate motor cost vs having a shop build a long block?

The lovely LBC
Just wondering how pricing compared nowadays. I last bought a GM crate motor in 1997 and it was around $1200. Anyone know how much they run now? How has had a shop put together a long block for them lately? How much was it running? I understand it cost more when you install a different cam, heads, etc?
 
Depends on the useof the truck.

Factor crate engines come with a decent warranty.

HP or tourque requirements for wheeling in different types of off road use my require a custom build.

If you know a shop or someone who uses one, and can be confident in the build, go for it. I always like using the local economy excuse for building a little more HP.

I did put a new GM stock 5.7 in place of the 5.0 that had a rod sticking out. And I wheel the crap out of the poor truck. And daily drive it.

If you are pinching pennies but not in any hurry, save to get what you want/need.
 
Hard to beat the GM crate motor, dropped off at your house, no shipping, with a warranty.
 
Chevy dealer will only warranty a Mr. Goodwrench replacement engine if its the original size and type originally installed in the truck,for non commercial uses,I was told by their parts counterman...

Prices are about the same as having an old engine gone thru completely...personally I'd prefer brand new,because all machine shops do make mistakes once in a while,or have a bad day,if you get my drift..

Too often I've heard of a rebuilt enging going bad shortly after the install,and the blame game begins--machine shop usually blames the installer for doing something wrong like failing to pre-pube the oiling system or not breaking the cam in right,used the wrong oil,etc...I know more than one guy who had to take a shop to small claims court to get any refund..since its a your word against theirs deal,its hard to reach a satisfactory settlement..
 
I agree with diesel4me. Brand new engine vs. one which might have a crack, or something gets overlooked ... unless you're trying to match serial numbers, I'd pick up a new one.
 
most of the time a rebuilt fails from assembly person skipping around or not doing attention to detail if you ask me .

if I was to ever get one remaned in my area there is a machinest with around 6month back log . and he only machines that's it.

also friend did a big hp 454 few years back . all done was good motor but add it all up and he could have had a built create motor delivered with full warrenty and more power for less .
 
GM crate motor warranty is void if not installed by an ASE certified mechanic.
 
:whistle: I got 4 of them :popcorn::pimp:

You probably earned them and deserve them. I know of quite a few around here that are worthless.

A certification is only as good as the person holding it. If the dude doin' the work don't care, its toilet paper.

Same goes for welding certs. When a welder applies for a job at my shop and says he's certified, i tell him "That's nice, now let's see what that paper is worth."

9 times out of 10, i send 'em packin' cause they aint got it.

To the original poster, sometimes a gently used motor is a good way to go. Especially if you can hear it run and the price is right.

thats not stated anywhere in the warranty for my kids motor:dunno: I read it like my life depended on it. only odd thing that voided it was not having a new or rebuilt radiator and water pump at time of install and reciepts for both

It's been a while since I've bought a crate motor. Every one I've ever brought, that clause was in the fine print.
 
My last 2 454s where used. One died early.................








With 14 psi of turbo. The other is happy as ever.

:bow:

why is usually the guys with the master cert that thinks that paper says "never wrong"

OP, I'd rather build my own in a toy/custom. stock I'd go for crate/warranty

Although this is true, it is often hard to know the quality of a used motor.

For $3-500....probably makes sense. $1000 ish, maybe, if you know the owner well.

Much over that, it seems to be a large gamble when it comes down to the time it takes to install.

My crate motor for my TBI truck was $2000, shipped from Summit or jegs, and showed up on my doorstep. Hard to beat.
 
The issue I always have is, people calling a rebuilt engine, like from Summit or Jegs, create engines. Yes they come in a create. But they are not all new components. Some are. But not all.

A friend was looking at a truck and wanted me to check it out. Had a brand new create engine with 300 miles on it. Started the truck, low end knock. Turns out, the engine came in a create, was a rebuilt from summit. He bought the truck cheap enough that we pulled the rebuilt engine. One piston had a cracked skirt and a wrist pin was the wrong frickin size. Runs ok now.
 
I've had good luck with local rebuilds. Do some research and find out from local hot rodders, etc, about who they've dealt with. Often they will know what your best bet locally is. Crate motors are good too, but I have heard of people having warranty trouble with these also.

I like the local rebuild since they are close for warranty (vs shipping) and it's nice to deal with a person/owner to resolve the issue. I've never had to go in for any warranty though. Guess I've been lucky but I have also been careful with install and break in. Like I said, local hot rodders/enthusiast can be your best source to find a reputable stand up local shop.
 
Agreed,if someone gets a "bad" motor somwhere,word of mouth travels faster than any hot rod does!..ditto for a place with a good reputation..

Looks like we are right in the same area. I used a GM Goodwrench crate engine for my K5 last year. It was $1700 with free shipping from summit racing. It runs great and is quiet. I used a new water pump, had a new core put in my radiator, new wires, cap, rotor, plugs, tstat, belts, etc. I didn't want to mess with trying to get more power out of a tbi engine, so I went stock. I had the new engine to put parts onto as I was pulling the old engine. It was a great choice, but the stock power level on an 88 5.7 is crap, especially with 35" tires.

My pickup has been another story. I went custom and local on it. I got over 100k miles on the 383 from star auto in Redlands, but the machinist that did the work is no longer there. It failed with a head gasket and it looked as if he failed to deck the block. That block had the same head gasket failure when it was a 350.

Two years ago I pulled the 383 instead of doing just head gaskets, since it had hard miles on it. I had it built into a 406 (different block) and had some major porting done on the aluminum heads and intake. This time I went with a 10:1 CR scat cast crank, forged rods, hyper pistons, hydraulic flat tappet cam (comp 270h magnum), and kept the roller tipped rockers from the 383. It ran like a raped ape and had incredible low end torque, that you could really feel from 2500 to around 4800 rpm (by seat of the pants feel), but still pulled well to 5500+ rpm. I need to go to a bigger carb, so I never saw it's full potential. It was based on a magazine article called 406 Impersonator. It's a small block that pulls like a big block. Their dyno tests and dyno runs on other engines that my head guy worked on were rated at 420hp and 525tq, with something like 470tq at 2500 rpm

Last month, with 27k on the engine and trans, I lost the trans and learned that the thrust bearing was toast on the engine. It is now being rebuilt by the best friend of the guy that builds my transmissions. The trans guy is the only employee of my uncle who owns the trans shop (lowells automotive in Fontana). Engine shop is BMS machine in San bernardino.

There were some skipped or less than perfect details with the machining and assembly of the last build. BDS just got a new forged crank for my rebuild and sent it to their crank guy (the only step they don't do in house). The crank had to be turned to be trued. It was new and a major brand-still have to ask what brand they chose. It was turned and re-heat treated. The cast scat cranks have had quality control issues with surface finish and squareness and stroke. The last builder used "P" bearings, which are supposedly bottom of the line. The new guy will use "h" bearings.

The new build will have a full roller cam and rockers and the guide plates will be adjustable to get good valve train geometry. We are reusing the hyper pistons, but the newer forged pistons can be run pretty much as tight as hypers and they weigh less. I just can't justify the money when mine are good and it won't make much difference in the build. If it had to be bored again, I would go full forged.

It all depends on what you want to do with the engine.

My K5 needed to be cheap and reliable while working with tbi.
My 79 C20 needed to have as much torque as possible out of a small block, since I didn't want the expense and hassle of swapping a big block (I already have near a grand in headers, and a swap means a smog referee).
