The technology is out-dated but it is a good block, crank and rods. Pistons would need to be swapped by most people.
I would try $3500 ?

The engine specifics include cast iron open chamber rectangular port cylinder heads with 2.19 intake and 1.88 exhaust valves, ³dimple² 7/16 bolt steel rods, and forged 12.25 compression pistons. The cam is a flat tappet solid lifter 560 intake and 600 exhaust design, necessitating setting the valve lash regularly for ultimate performance.
The block featured four-bolt mains, and the ³XCH² nomenclature in your stamped block number is proof it is indeed an original LS7 block. The bottom end finds a forged steel 4.0-inch stroke crankshaft that is externally balanced, meaning Chevy made special flywheels and harmonic balancers weighted specific to the 4.0-inch stroke crank.

Collector Car Corner: Solving a Chevy LS7 454 engine mystery

I bought a 69 Camaro from a guy in Texas with an old Chevy crate engine in it called an LS7 Big Block. He installed the LS7 in the car in the late 1980's and the number stamped on the block is TL02XCH09488093.

Keep in mind we can get a new build with much more useable power for around 6-7K. Being the former owner of an L88 crate, aint much collectability to them either, bur t some. You'd be lucky to get 5K i should think, but I dont collect so?


Vin stamp is questionable. My L88 was defintely 'CE" stamped before we decked her down to 3 thou. Again, not a expert in that tho. Racers in Oswego NY used L88 / LS7 for their supermodifieds, which is where i got the L88 second hand.

ALSo, once they are re-machined, any "collector" value drops. The ones that are "untouched" command the coin.

Where are you located?

Two years ago I purchased a 1967 Chevelle that had one of these engines in it XCH but it also came with the original matching number block to my Chevelle and wanted to go back to all original. I originally advertised the LS7 on Ebay and Craigslist for $5000. I did not get one person interested in it. I lowered the price to $4200. Had one person call but just wanted to BS about it. I dropped the price to $3500 firm. I had one person interested and he came and looked at it and offer me $3250 complete from demon carb to oil pan including the flywheel and a set of stainless steel Hooker headers. I felt I gave it away but just could not get anyone interested in it. The gentleman I bought the car from said it had 12½ to 1 CR and I had to use 110 octane fuel in it and the closest gas station that carried the 110 octane was 28 miles from my house so it had to go. The engine only had 35?? miles of it and I sold the Richmond 4+1 trransmission that was behind it for $1500. There again I listed that for $2500 and was offered $1500 so I took it.

The LS7 engine is a good builder. Back in the early 80's buddy bought one from the local dealer when they were $2500 in the crate. He took it apart and had it blueprinted and re-clearanced by a machine shop. The machinist said he cringed every time someone bought one of those in, the clearances were so bad from GM. I am like some others here, I cannot get diddly for a BBC here where I live. I have a nice 468 with sq. port head with all good parts balanced, cannot even get more than an offer of $2700 for it, for that it can sit in the corner.
