screw it ima go .030 over if i crack a sleeve then ill resleeve with Darton MID sleeves and have a secred cubed engine on a 5.3 cast engine :D
ERL has been resleeving all gen 4 blocks for years now. which can be a variety of cube sizes
Plus they aren't having the same old problems with dropped sleeves like the used to have. Seems to be a legit alternative for more cubes than going with an iron block these days
weight is the main reason why i got this block but as far as big cubes its cheaper to make an ironblock big cubes. i can get 6.0 cores for 3-500 bucks.Quote:

Now, with the new sleeving processes that are utilized, a large cube aluminum LS is an option. Big cubes, light weight= win win
And probably still cheaper than an LS7 or C5R block
If weight is all you were worried about you didnt get much difference. 60lbs I think.Quote:
