Considering that these are the blocks of choice for most max effort applications. And, without getting into a cheerleading competition, can we have an objective discussion comparing the ERL reworked LS2 blocks to the Warhawk and LSX? Obviously, the aluminum offerings are lighter. What about strength, availability, compatible cylinder head offerings, cylinder thickness/max bore, stroke capacity (considering clearance, deck height options, rod length and pin placement, etc.), legality for class racing, cost/value, and any other features/benefits that one might have over the others. Please try to keep it civil

Thanks,
Rob

 

 

Besides weight savings with the aluminum block.....I think without argument the LSX GM iron block wins in every single category, including being A LOT cheaper. As long as its one of the good LSX blocks.

Unless the longer 5.800" Darton wet sleeves can be used in the aluminum blocks than the sleeve length of the LSX GM iron block also won't have the longest sleeves so strokes can't be too long.
