Ok i've seen a couple of guys claiming to have dynod at 1100-1200hp range but these guys said they had to drop $4000.00 into the short block alone to handle this power, LS2 vette!!!!That was fly HP #,Motors were built by Lingenfelter!!!Total cost for engine work $16,000 These guys were racing in I believe an SCCA event, so these motors were set-up for good reliability as well!JeffP said:I think your refering to stock shortblock. I would think at least 900-1000hp would be possible from the block itself. I'm concerned more about what HP point do you have to change to a cast iron block or different aluminum block.
A 1000hp was just my educated guess. I was looking for more fact which sounds like from dbluegoat is accurate.jcain said:if you already know, why ask? i too, believe the crank and block are good to 1000+.
