Questions about an engine rebuild

Now, it's spelled correctly.

 

I am no motor man but I have more than 1500 dollars in machine wok on my 283. Put the crate motor in and let the young man drive you can rebuild the old motor in time and save him some money for tires.

 

Crate engines are like a box of chocolates..... Ya never know what yer gonna git!

 

I wonder if the Crate Motor heads are new cast too, or if they are original GM heads?

 

Here is what they say about the motors:

These are excellent entry-level performance engines for older cars, trucks, and street rods. All of the parts in these engines are brand new. These Chevrolet Performance Goodwrench 5.7L/350 c.i.d. engines have approximately 8.5:1 compression with an base horsepower rating of 195 hp and capable of up to 260 hp depending on intake and injection setup. These crate engines have a 4.00 in. bore and a 3.47 in. stroke with 4-bolt mains and 2-piece rear main seals. Camshaft specifications are .383 in. intake lift and .401 in. exhaust lift. The open duration is 194 degrees intake and 202 degrees exhaust at .050 in. with a 112 degree lobe separation. The cylinder heads are cast iron with 1.94 in. intake valves and 1.50 in. exhaust valves, 76cc combustion chambers, and 7-bolt style exhaust flanges. These engines include painted valve covers, oil pans, and timing covers. They are drilled for both left hand and right hand dipsticks.

Where in this does he ask opinions on what we think of a GM 350 crate motor?

Ask around on here and maybe at a local race track to find a reputable automotive machine shop. They will have several levels of rebuilds to offer and will guide you in the right direction based on your needs.

Be very weary of anyone trying to convince you to swap yours to a 350 crate due to convenience or pricing.

 

i have a1969 327.. back in the back somewhere
ya know i oughta get it out and running ...
NA.. some day some deserving soul will
talk me out of it....

 

Give this man a cigar!!!

And I will add that a qualified machine shop can "taylor" a build to "your" needs.

Crate engines are a "take it or leave it" deal.

 

C-10 I think that GM is rating the lower end and not the block. When I can find them I prefer the Mexican block they usually have a higher nickle content. At least that is what I have been told.

The cheapest route to go any more is a crate motor. You can buy ghood ones even from GM that have great output out of the crate. My problem with them is that they are the true belly ****on motor.

Outlaw is correct in his evaulation about bang for $$$ unless you are an automotive machinst and have access to the shop you cannot build an engine for near the price of a crate motor. I still prefer to build my own, but it is part of the process of retaining my sanity.

If I have a well worn small journal I would seriously consider going through it. But that is me personally, I wouldn't think about resale value and numbers matching, that is not where I am at. I am not a restorer and I don't build for a living any more.

Before I made a decision to change to a different engine in the Impala I would tear the 327 down and see where it is at. One may be plesently surpirsed at the overall condiotion of the old engine and it may not take any major machining to make it right. There are a few tricks that can be done if one knows who to ask.

 

Good point, but i think the gm crate was suggested as an alternative to rebuilding.

i think maybe the key for this engine is to never rev it above 4900rpm.

 

Your friendly local machine shop should offer magnafluxing the block as standard procedure after cleaning and before ordering any parts for it..If not, ask them to do it. If they say they can't, find a different machine shop.
My old astro van came to me with a 260 HP 350 goodwrench crate motor..I put 40-50,000 miles on it with no problems...even tho you didn't ask about crate motors.

 

Okay, this spurs my interest and begs to ask.....

A 350 in an Astro van???

They only came with V-6's.

 

I heard Wal-Mart will soon carry crate engines for all makes and models. I've seen powder rods haul ***. Stick with the original and build it yourself. Far more rewarding....

 

Why not? Sears did. (still does?)

 

My 62 Impala lost the 327 back a few years. was getting it all rebuilt put in a new zz4 long block while i was building the 327. Guess what the rebuilt 327 is sitting on a stand that zz4 runs so good why change it out. Maybe some day
