SLP iron shortblock? Has anyone tried these pups?
They have an SLP factory about one hour from my house. The part I find interesting is that you get to choose between a 10.1 and 9.1 compression ratio...
I have shaved LS6 heads (milled .055) and would go with the 9.1...
After considering all the variables and suppliers, this does not seem like a rip off for the $3,500 - $4,000 they are asking...

So Brian from SLP has cleared up a lot of confusion as indicated below. Since Brian's post is several months old I was wondering if anyone had purchased the 402s. The last I heard they had not shipped any...

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 (SLP)

I have a few bolt-on things from SLP; no real issues... Some of their stuff is very expensive (headers) but other stuff (lids) are OK....All-in-all - they have been knocked a bunch unfairly I suspect. Some of this relates to their conversion to Mustang parts since GM discontinued the F - bodies....
It is always a good idea not to be the first in line; however, Example; the first Eagle crankshafts were recalled becuase of MAJOR balancing issues... Some guys were paying $600 or more in labor to balance them....others had counterweight clearence problems, etc.
I've been there and done that!
I would definately wait until at least the second production run to see if anything bad has happened to the SLP iron blocked strokers and how they treat customers who have issues.
