SLP 402 short block questions "ZL-402" LS1 Short Block (High Compression)
Im looking at this stroker short block, i think my heads and a cutom cam would be great for this motor. Will stock LS1 heads bolt up to it? How about the stock oil pan and timeing chain covers and all?
It looks like a awsome deal.

I haven't heard too much about the SLP 402 kit....so i won't comment on its quality.
But all your parts will bolt up considering it's just a 6.0 iron block which is the same as your 5.7 alum block....just with a bigger bore and iron instead of aluminum.

I think they used to have an iron ZL-402. Currently they are using aluminum blocks according to this.

Crate-Engine Assembly, "ZL-402" LS1 Short Block (High Compression)
--------------------------------------------------------------------------------
With GM’s versatile "Gen III" small-block gaining popularity as the foundation for a wide range of high-performance engine build-ups, market demand for an affordable LS1 stroker package has become increasingly intense. In response, SLP Performance Parts has devised a revolutionary new Gen III stroker short-block assembly, one that offers unexcelled performance and durability at a truly accessible price.
Dubbed the "ZL-402" to reflect its beastly 402-cubic-inch displacement, the package is chockablock with such race-proven hardware as a new GM LQ9 block, a 4.00" forged steel crank, and 4.00" forged aluminum pistons. With the right cam and heads and a properly tuned PCM, the ZL-402 is fully capable of producing over 575 hp and a similar amount of torque in naturally aspirated form.
This package is sold only in short-block form, minus manifolds, camshaft, oil pump, and other ancillary equipment. The obvious advantage of this approach is that it allows each customer to formulate a parts combination that is perfectly suited to his or her needs. (For those who prefer "one-stop shopping," SLP offers a host of uninstalled options on an à la carte basis.)
Although designed primarily for use in late-model F-Bodies and Corvettes, the ZL-402 also makes a superlative choice for most street-rod, muscle-car, and truck applications. Best of all, it’s sold outright, eliminating the shipping hassles, protracted vehicle downtime, and additional out-of-pocket expenses associated with core returns.
