Please my friend, im not trying to be an ass but i think i know a slight bit more about these motors since i have a custom built 383 that was garage built but machined through LME

Not trying to be offensive here just stating what ive learned from being in the game for the past 6 years now EXTENSIVELY

I know about puting power down trust me!! Im not saying the blocks are crap so dont take me wrong, I merely said with ALOT of power, your chance of ceacking an "ALUMINUM" block is much higher than cracking an "IRON" block. <<<If that statement isnt true then show me how you figure that an aluminum is stronger than the iron
