Our Street-Strip Series 388 short block has all the ingredients to pack the punch you're after.The aluminum block 388 Darton Sleeved LS combo is a proven performer and is quickly becoming our most popular short block combination. The 388 is a big bore (4.125") with a short stroke (3.622") making it a high rpm screamer and still allowing you to run a cylinder head that requires larger bore sizes, like the LS7 Style cylinder heads. This combo has become the go to for power adder guys, no matter if it's boost or nitrous!
