I was told GM made the LS6 454, 450hp 500tq available in the late '80s, early '90s to
Chevrolet dealers only (crate motor), in limited quantities. Anyone know if this is true? Production numbers? Cost?
any info would be appreciated. thanks, max

if im correct i think they might of cause ive seen some late 80's early 90's silverado 1500's runing around with 454's in them and it has a 454SS decal on the rear panel on the truck bed and it's not some ricer decal it looks like it came from the factory so i dont know if i am totaly correct or not

LS-7 was also quite popular in a crate, and available through at least '96 (454, 460 HP) Easily identified by the solid lifter "rattle". Bad-ass!

I don't think the 454 SS pickups had the LS6 in them...somewhere i saw a horsepower rating of 260 for them...I never have seen the Torque rating...but i was surprised by the low horsepower...and i have seen that rating more than one place

I believe I have the engine you were inquiring about, here is what I have, 454 block casting # 14015445 4 bolt block, heads 6272990, crank 3867416, rods have 7/16" bolts, and pistons are trw forged dome pistons. I know it is a GM highperf crate engine with solid lifter cam. The block also has 10606xaa stamped above the timing cover. My question is can anybody tell me the compression ratio? I have found crate engines with 10.2:1-12.2:1. I am planning on putting this engine up for sale I just want as much accurate detail about it before I list it.
Thanks Ryan Folk
