Bryan ... looks nice ... Seeing how I am in the market for a short block this appears to be a viable building block that I can improve on over time. Since my LS2 #8 cylinder is now missing a big chunk out of it I need something fairly quickly but I want to use as many of my LS2 components as possible. I can't drop all the cash on a long block so I am gonna ask some dumb questions 
1. The LSx block information claims you can use any LS series head ... I currently have LS2 heads ... Will they work?
2. If those heads work I assume the LS2 intake will work as well?
3. Is the side profile the same as the LS1 / LS2 ... IE header clearances.
4. Basically all of the LS2 accessories fit?
5. What won't work?
6. What is typical time from order to shipping?
Thanks for the input!

Hello,
Here is the info you were looking for:
All of your LS2 components will work with the LSX block. The LSX uses the same cam sensor configuration as the LS2. So your front cover will work. I would use a new LS2 double roller timing set with the new shortblock. The LS2 heads will bolt right up to the LSX block. After machining the LSX block will have the standard 9.240" deck height. This will put your cylinder heads in the same location in the engine bay. So your headers will clear without a problem. You will be able to use all or your LS2 accessories. The LSX block comes w/ a cam retainer plate & rear cover. So you can swap over your front cover, oil pan & valley cover to complete the engine.
The build time on the 454" LSX is 3 to 4 weeks. LME have been hitting 3 weeks on many of our recent orders!!
Feel free to ask any other questions.
Sincerely,
Bryan Neelen
LME

I went over this with Bryan myself. The outcome of it was I went with a low comp 402. My business partner has one from them and we are at 825 RWHP with the restrictor plate in and it living just fine. The think the stroke and the piston thickness has alot to do with it for a boosted application. LME is top notch and I wouldnt hesitate to call them. Bryan or Pecus will answer the phone
and answer any questions you have

LME, I have a few questions about the LSX setup. Normally I would PM such questions however i believe this info to be valuable to all.
1.) Will LS1 designed motor mounts work for the LSX and are they in the same location? Meaning with an LS1 K-member setup allow an LSX based motor to bolt into it using stock (hopefully not) or aftermarket motor mounts?
2.) I hate to ask prices as they are completely subjective, but what would you say on average (or a range) or prices for 427 built LSX with the LS7 heads? I just need a ballpark figure in my head to get the ball rolling.

If you are looking to build a 427" LSX longblock w/ GM LS7 heads & intake w/ no additional port work, just upgraded springs. You would be looking at aprox. $11500. The engine would only lack the oil pan.
You could also do a complete 427 w/ ET LS7 heads w/ ti valves. LS7 Intake to sheetmetal oil pan w/ ATI balancer for right around $15000.
So all in all you will be right at $11,000 to $15,000+ depending on what parts you currently have and how complete you need the engine.
Thank you,
Bryan Neelen

We want results my man. Any dyno numbers yet on 454 LSX or even 427 LSX?
Does anybody have any LSX results yet on any car period! Can't wait until I can afford to build me one of these!
