With a good tune and good fuel you should not expect to have any problems. Bob

LS-3 Block Strength NO, to be fair AND as listed by GMPP.
There are FOUR items that will make this work.
1. Install LS-7 "billet" main caps.
2. Use/install a 58x crankshaft target wheel.
3. Use Chinese head studs.
4. ARP Main Studs.

I didn't know about the maincaps and the ls7 having steel billet. But under power the cap try's to fold in half which kinda causes it to twist in the bore taking out bearings. Not sure there needed at the 900/1000 range but the safety would be there
The 60 tooth wheel provides better timing accuracy creating a more stable tuneup

I run all standalone stuff. The block fill is 50/50 on the internet weather it's needed or not. Mine is not. But by design the LS block is rigid being a Y design, and mine is motor plates front and rear providing more stability and getting the force off the side of the block
58X reluctor wheel crank is far from a "necessity" the Billets caps are a decent idea to try and give the block a little more rigidity but know that 1000whp is asking a lot from a factory GM aluminum block. Your flirting with that line at that level. I've seen my fair share of LS2/3 blocks thrive at 900whp and start spitting bearings out at the 1000whp mark.

Powdered Main Caps Hi SBF2, the GMPP rating in HP is given, largely, by Main Cap material.
The LSA SC block's main material was steel.
The "truck" block was Billet Steel.
Thus the possibility to "find" a broken LS-7 block, low cost if not free, would allow a main cap interchange.
MY witness of a LS-2 "powdered main" was a cracked #5 @ 1000 RWHP.
The use of a 58X TW would be of great help allowing much better Spark Accuracy, GOOD for engine life.
