Anybody running SLP 402 LQ4? Any issues with this stroked-forged iron block?
I heard the assembled short block is externally balanced any does not carry a warranty.

I've heard it's not released yet. The prototype is still on the bench, being tested/trashed. I remember a post here saying it's internally balanced but no warranty.

I personally wouldn't touch it even if it did come with a warranty. I'll go to MTI or TTP or HPE or TSP. Nothing SLP touches my motor. I'll be damned before it IS my motor.

..I don't know ....it seems buy the time you buy all the parts you would be close to the SLP price ....that is without machining, assembly etc.

How can the quality be questioned when the engine hasn't even been released yet? 
I am not defending any shops here, just posting up ALL the information. At this point these engines just aren't cheap to build.

Guys -
Thanks for the interest in SLP's new ZL 402 short block. I would like to clear up some of the rumors, and offer some facts about the package. The package has not been officially released quite yet, as engine #1 is actually still busy being thrashed/tested on our dyno. All testing should be completed within a week or so.
Anyway, a detailed editorial about SLP's new 402 was published in the May/June 2004 edition of Pontiac Enthusiast Magazine (the only typo is the 60# weight reference- the iron block weighs 100# more than the aluminum. The cost was originally stated as $3995, we have since LOWERED it to $3595.). I recommend reading the article if you are interested.
Here are the main ingredients:
1- Production 6.0L cast block
2 - Internally balanced rotating assembly
3 - SLP spec'd Eagle 4" crankshaft
4 - SLP spec'd 6.125" I-beam rods (Eagle and Manley)
5 - SLP spec'd 4" pistons, 2618 forging (Ross and Manley)
N/A version (approx 11.2:1)
Heavy-Duty, Forced Induction version (approx 9:1)
6 - $3595 retail
7 – 402 CID 'rotating assembly' sold separately (parts only, no block, not assembled)
8 - SLP will also offer 383 CID rotating assemblies (no short block 383....right now)
Best regards,
Brian

What a great post, I just called HPE and they quoted me a WAY better price than any shop I have called, and their turnaround time is great in comparison. Long as they do the work right I would say they are a great vendor.

Other shops have been quoting me 4500-5500 for a 408CID Iron block.
These guys first off had a price of 3900, the only issue I have with them so far is they wanted $200 for a modified oil pump which seems to be about $40 higher. I'm glad I found this thread before I got the same setup from a different shop for almost 1k more.

It all depends on quality and reliability of the motor. I would gladly pay an extra 500-900 if i knew with out a doubt that i would never have to worry about it and if somthing did happen the shop would stand behind there work.
