LS3-Based 418ci Engine Build - Big Power, Small Budget

Texas Speed Builds An Affordable 418CI LS Engine Part I: AssemblyWhen first introduced in 1998 in our beloved Birds, the 346ci LS1 was the proverbial tip of the cubic-inch iceberg. Much like PMD's classic engine that began life as a 287 and evolved to a 455 with both bore and stroke enlargements, GM has taken the Gen III LS1 and LS6 engines and developed a host of Gen IV block and head designs that are offered in both OEM platform engines and GM Performance Parts crate engines. Everything from a 4.8L LR4 (293 ci) through a 7.0L LS7 (427 ci) can be bought over the counter. For enthusiasts looking for max performance, the cast-iron LSX block and the LSX tall-deck block can be purchased and built to achieve up to 482 and 500-plus cubic inches, respectively.
