NOS LS7 454 Crate Engine

[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.

----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

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.

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)

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

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.

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;.
