Texas Speed & Performance 427 CID 7.0L Iron Giant LT Gen V Short Block

Build your high-output Gen V LT project around the Texas Speed & Performance 427 CID 7.0L Iron Giant short block.

This is a short block, not a complete ready-to-run engine. Texas Speed identifies LT truck applications and specifies front-accessory modifications for LT car installations. Verify your exact application, cylinder heads, oiling system, accessories, electronics and installation clearance before ordering. Inclusion in LT vehicle and swap collections does not mean it is a direct replacement for every LT1, LT4 or LT2 installation.
