The Texas Speed Brawler 427ci LT1 Resleeved Wet Sump Short Block is built for Gen V LT1 engines that need maximum displacement and strength while keeping a factory style wet sump oiling system. Texas Speed resleeves a factory LT block to reinforce the cylinder walls for extreme horsepower and fills it with forged internals, rating the combination as 1200 horsepower capable for high boost, nitrous or naturally aspirated builds.
The rotating assembly uses a Texas Speed forged 4.00" stroke crankshaft, Texas Speed 6.125" forged I-beam connecting rods and Wiseco -20cc forged pistons engineered for boosted or high-compression naturally aspirated applications, with ARP main studs for crankshaft stability and block rigidity. The short block is precision machined and balanced and ships with 16 quarts of break-in oil on an LT1 engine stand inside a shipping crate.

Why does Texas Speed resleeve the LT block?
Resleeving reinforces the factory LT block for extreme horsepower. Texas Speed states the resleeved block delivers superior cylinder wall strength, which supports the larger displacement and the 1200 horsepower rating of the Brawler 427.
