LOL, I don't agree with that. It seems that the LS7 Block has taken some bad raps.
It depends on your horsepower level. I have heard of problems with the sleeves on some road race applications but you can have that with any sleeved application.
The masses seem to want more cubic inches. That is fine but there is a point where your gains diminish. For a street application you cannot beat the torque generated by a large cubic inch engine with a long stroke. For a racing application there comes a point when I will make more power (and reliability) with a shorter stroke. We don't have the heads at this time to support a full out large cubic inch deal. (440+ cubic inches)
I want to try some 380 to 400 cubic inch combinations with the currently available heads. I think they will make just as much power as some of the big inch deals.
I think that the LS7 block would be a great base for a 500 to 700 HP short stroke engine.
Now just wait until we can get our hands on the LS9 Blocks.

Steve at Race Engine Development can resleeve the LS7 and any aluminum block for that matter. I would check with him on the max oversize bore after resleeving. He can also resleeve the LS1/LS2 blocks to a 4.125+ bore also... Which might be more cost effective for strength anyway.

9600rpm
Pro stock 500 cu.in 7inch stroke? NO!!! I am going to rev this thing to the moon!! I love crazy rpm. It's kind of like cutting wood with a chain saw. The work isn't that fun, but running the saw is! I tape NHRA and strain my eye's to see what rpm they stage and leave the line at. Also when they shift.
