your want a new GM mark 4 454 two bolt main block ? or 4 ? looking for a new iron block like a big m or world block... or bowtie ? who has the best price on what block what caps iron or steel that bore size do you need how much work done ? why i am asken this is you can get new blocks many ways . has for quality i fixed all of them see them all get hurt and i fixed alot of them there all good to a point . gm blocks may not always fix the best .not as heavy but are weaker in some spots. dart ball mills the out side oil pan rails this is very dumb and i told DART THAT they are DUMB they bust out EZ . there maching over all may or may not be better then world blocks but the world have a stronger oil pan rail .looks like mildwest racing.they may have the old pro block tooling ? WORLD did sell it or was try to? that could be a good casting ? as the old pro block is very solid block . there is some china stuff out there now.. i have a china 351w tall deck block with C mains block looks ok .needs alot of prep and hard ware bolts washers are junk after i machine the block its going to get ARP hard ware when it get s put back together so you may not save any money going with the china blocks. still to new to know much about them

And to add to Pat's comments

GM is no longer making the big block---and used cores can be $400-$700 dollars

it needs to be a 4 bolt with 4.25" bore and a 9.8 deck height, i will need to machine it 90 over and deck the block to fit all of my new components. my block after machining we found a large hole near the cam in a water jacket
