New Chevy 350 Bare Block 1986 On

Brand new 4-bolt main, one-piece rear seal (1986 and later) Chevy 350 bare block. This Chevrolet engine block is less money than the cost of buying and preparing a used one. Why bother with all the hassle of a used block at +0.030", 0.040" or larger bore when this new block is ready to start assembling at standard 4.00" bore (and still with lots of life left). This block is ideal for anyone re-building a tired engine or wishing to build a high performance engine from scratch. We have built many 450 HP engines using this block without failure. This is the same block used on Chevrolet 350 HO crate engines.
