Lets talk about what you want to see in a Gen III aftermarket Block?
block isnt an issue till around 1800hp ish and depending on crank stroke can raise or lower that number.
my biggest issue is cam gear. that needs addressed before anything block related is. by my fuel usage logs ive seen 1900hpish with bge block n head castings. both held up fine.
however i have struggled with ignition issues from day 1 due to cam/crank sensors, wobbling timing trigger wheels on the cam, and currently a dies for no reason issue. i blame on the timing gear. as nothing else has not been replaced more than a few times.
