NOS LS7 454 Crate Engine

[Cranberry70SSL34]

I have a new in the crate, never been fired 454 LS7 xch code engine. It was purchased in the early eighties and been stored in a climate controlled garage. It is just as it came, with black painted engine, valve covers, and oil pan. Not many of them around anymore. Thanks.

Price is $9,999.00

Man that motor brings back memories. I purchased one of the last ones in 1991 from the chevy garage for $2900 out the door. That motor is a beast.

[Cranberry70SSL34]

By the looks of what you are always selling it seems you have been really acquainted with lots of big block beasts Mr dlv4540. Needless to say you must have lots of big block stuff.Yea it is a beast right outa the box. My uncle bought one and did absolutely nothing to it but put a holley intake and a 850 dp and put it in an all steel super stock body 69 camaro. The car ran 10.5 all day long with a bone stock ls7. In fact he still has the car and that engine is still in it. Oh and there also built to last. Thanks for the reply.

[dlv4540]

I agree and also ran a 850 double pumper with a holley blue pump to give it the gas it needed. I ran straight cam 2 in it at $3.25 a gallon. It seemed like a lot 20 years ago but would be a bargain price today. It is a very strong engine and will take all you give it. Will make a great motor for somebody. Goodluck with the sale.

[Cranberry70SSL34]

There were dozens and dozens of them in dragsters and all sorts of race cars around here all through the 90s with as little done as just a roller cam. A stock LS7 with a roller cam puts you in the 625hp range easy.

Having gone through the exercise of searching for and purchasing an early 70s LS7 engine, I must say I have never seen this kind of asking price associated with one, even if it is NOS. Have the prices on these engines changed that dramatically? The priciest one I found a couple years back was $5500 in about the same condition as yours - but i don't remember its specific year of manufacture. Was there anything particularly special about the early 80s versions? Just trying to learn here.

[Cranberry70SSL34]

Oh yes a never fired engine is drastically different than and engine that has only been run just a few times. The reason being a buyer doesn't know if its an hour or 50 drag passes. But if never fired,that can be proven and extremely hard to find. This engine is extremely rare period let alone the value of it being unaltered. In addition to these points, this is a LS7 from the early 70s and not the later version. This is truly a piece of Chevrolet history and the greatest engine ever built during the musclecar era. Probably not the last one in existence but very very few left and will probably never come across another. Its very difficult to put a price on a item nearing extinction. After explaining all these great points I'm starting to think I may have it priced too cheap but the price remains a great value at 10,999.99. Thanks for your interest.

[Tracker1]

Thanks. What is the casting date?

[Cranberry70SSL34]

The casting date is 205 day of 1972 and a build date of 0828XCH.

[Cranberry70SSL34]

Definitely the greatest engine package of musclecar era.

[Cranberry70SSL34]

Real deal unaltered never fired LS7.

My experiences with
N.o.s. 30 to 40+ year old
Engines
Are even though they have
Never been run .....
You usually have to disassemble
Them to a certain degree
To inspect them for light
Corrosion ( lifter valley area is common)
Lifter bores cylinder bores
And sometimes crankshafts ( usually just
Need polishing ) on journals
Good luck on sale
Great piece

[Cranberry70SSL34]

Well it looks like day one in the lifter valley and down in the camshaft area. Has been in climate controlled place always. Inside my house most of the time. This engine is definitely ready to go no corrosion. Thanks for your insight.

My high school buddy bought a crate LS7 from Reggie Jackson Chevrolet in 1985. We opened it up and it was full of foreign material--dust, grit. Disassembled it, had the block tanked, cleaned everything up and put it back together. Still in his '67 SS396 Camaro and still the baddest-a$$ Rat for the money. With race gas and proper timing it just shreds rear tires.

[Cranberry70SSL34]

My uncle bought one in 1990 and did nothing to it but put an intake and Holley 850 in a super stock 69 camaro and run 10.5s all day long. This motor absolutely doesn't need to be tore down.

[daverd]

Well it all depends
I've built and rebuilt probibly
500!to 800 engines
In my lifetime
I am a certified Gm diesel
And auto tech
( Any thing that's 40+years old
I'd pull it apart to check it)
I've found under torqued things
On brand new engines too
I do this stuff for a living .......!!!
( not just a hobby)

----Trust what David says. It could save someone a lot of irritation. Its no big deal to take a crate motor apart and just check things out. The engine isnt devalued in any way. As a matter of fact, I think the value would be enhanced if I was interested in this crate motor if I knew it was already done. Also, fresh cam lube could be applied to lessen the chance of a lobe being wiped out. The motor has been sitting for a long time. What ever was on the cam isnt fresh anymore and may have hardened a bit.....Bill S

[Cranberry70SSL34]

Well it looks super good down in the lifter valley and under the valve covers with not even a hint of corrosion. I'd say roll on but yea when you spend the bucks on such a nice piece there's nothing like knowing. So its totally up to the purchaser

Thanks Bill Better to err on the side of caution ...I've seen people
Skimp at the last minute .....with very expensive results ..

[miket1]

It doesn't take much time to pull a pan and valve covers to check the torque, I would want to reseal the pan anyway before installing in my car, and it's easy to install an old distributor to pre oil the engine.

Bump to sell

[Day2_69Z]

Is this a small pad or large PAD Block ? The True XCH LS7's are from 1973-1976....with large front stamping pads. Using 2nd Gen L88 Rods 180 ZL1/L88 Cams...pushrods rockers etc. the later ones are the Generic type that Chevy marketed as LS7's , L88's &amp; LS6 Crate motors ... assembled with the mass produced Truck type blocks , Rods and Cranks...using small pads.... Check the Casting #s ..freeze plugs and pad. An early 80's purchase can be either one....All the 90,s Engines are Early Period INCORECT in appearance and content!!!! Don't be fooled with LS7/L88 monikers the Real Ones are Early builds and have the &quot;RightStuff&quot;.

[SuperNovaSS]

Are you saying later LS7s don't have full floating 7/16 dimple rods and 180 cams? I disagree. What do you base this info on? It's not fair to post this info, especially in someone's ad, without backing up your claim. I have had quite a few later LS-7 engines, both used and NOS and the internals are the same other than possibly a 7416 crank rather than a 3521.

My buddy bought an LS7 crate engine in 1987 and as soon as he got it home he tore it down and found dirt and grit inside. Cleaned it all up and put it back together. Still going strong in his '67 SS 396 Camaro.

[Cranberry70SSL34]

Absolutely a tear down and lube and spec check would be worth the time. Especially for peace of mind. Great engine. No genetic internals in this beast. It's got all the good stuff.

[Cranberry70SSL34]

Thanks mr xplant. I need someone to follow me around correcting my typing work. How much? Lol just kidding. I appreciate the clear up.

[Cranberry70SSL34]

New price. 9500 takes it.

[Schaffeur]

Hate to revive a dead thread, but is this unfired LS7 still around?

[Cranberry70SSL34]

Sorry man. I sold it back in November of 2014.
