should I block fill an aluminum block?
I have a brand new aluminum bowtie sbc race block,I'm going to use 11.1 static compression and a 8.71 blower on alcohol that is turned 20 over and made 23lbs of boost on my old sbc stock 400 block that cracked,just wondering if I should block fill it to the water pump holes,even though I dont want to,due to the fact it will decrease the value of the block if I was to sell it,Please somebody give me some good info on this,and my stock 400 block was filled,the aluminum block is much thicker as is the deck,Thanks
