LSx 454. Opinions?
 

I did try a search and nothing about an LSx 454 came up.
Does anyone have any opinions/facts or dealings with the new crate LSx 454 engine that GM is releasing? I did a little reading on it and it seems like a stout motor as far as going N/A, which is the way I want to go. I know it is not aluminium, so the weight is an issue.
Just wondering what you guys/gals think of it. THANKS in advance.:lateral:

i have the lsx454ho try mast motorsports they only do ls/lsx engines

We dont have our LSX motors packages on the site yet but pm our email me and we can get you pricing on our turnkey custom built 454 setup:thumbsup:

What are your thoughts/opnions on the LSx 454 since you have one?
Is your set up carb or F/I? Any input would be appreciated. Thanks!:thumbsup:

GM is goin to release 454LSX 620 EFI crate motor soon. Its based on iron LSX block and aluminium cylinderheads close to LS7s with 6 head bolts / cylinder. Intake is LS7 . GMs test car run 10.80 with it:wow:

I like it. Its the price that jumped at me. 12-15k. But its a very good short block as well. You could spray it as well, but you lose the warrenty. speaking of warrenty. 2 yr/24000 miles on a 620 hp crate motor.. not bad.

Its a very bad motor. i'm going to wait until I hurt my LS1 and then look real close at it, or someone elses.:thumbsup:

YES!! That is the engine I am asking about.
Sounds like a killer set up. Any thoughts?!?:_paranoid

We can do carb or injected we can set you up a complete package with warrenty you can pick the brand of parts you want from crank to heads and we can price you out a package. See our stuff is very close in price to the crate motor stuff but you get the extra bling like valve covers etc in our stuff... :thumbsup:

I just got that block in the shop.. the short deck.

We are thinking of going with a 440 build though. I need to research the wall thickness if bored out to a 454. I would rather sacrifice some displacement for better longevity.

Yes yes it is ! With 2 years warranty... Not to mention no-brainer gm harness/lsx controller kit :thumbsup:

There is a guy I know here in town, that used that 454 lsx shortblock, with 6.0 truck heads and single plane intake, holley carb and it runs 9.90's in a 00 SS Camaro.

I built my own verison of that combo for my Vette and it's a killer combo as with anything its going to depend on the set up. checkout LS1 Tech there are alot of guys on there that are starting to use that motor.

mine is f/i, 630hp 615tq they make 3 models lsx454 lsx454ho lsx454ss i got the ho mated to a 6l80 ,the only option i couldnt do yet is roller rockers there coming soon. mine is a turnkey engine. when i buy an engine its the dyno sheet and torque curve i look at most.good luck on your choice. i also found the people at gm know nothing about the motor yet.

Yes. I did read that as well. Sounds like you get more horses using the carb setup though?:_paranoid
I did do a search on LS1tech.com, but there were no hits. I am a member there as well, so I will look again tonight.

Thanks for your reply/info.:thumbsup:
