Lq9 408 Stroker Budget Build Aluminum Block
|
SAM's Judson Massingill got hold of a brand-new GM LQ9 block for us, and a clear advantage to its iron construction is that it allows added overbore potential versus an aluminum block. The SAM folks enlarged its factory 4.00-inch bore to 4.030 via a diamond hone--no boring machine required with this process! A torque plate (installed here with the ARP head bolts we'll be using) is mandatory to simulate proper cylinder shape after the engine is assembled, ensuring maximum power and efficiency.
