TSP 408 C.I.D. LQ9 Short-Block

GEN III BLOCKS ONLY

The Texas Speed & Performance 408 C.I.D. LQ9 Short-Block is built using a brand-new GM LQ9 6.0L iron block and comes fully assembled with a 4.00″ stroke crankshaft and your choice of 24X or 58X reluctor. This is a proven foundation for high-performance Gen III LS builds.

Key Features:

• New GM LQ9 6.0L iron block
• 4.00″ stroke crankshaft with 24X or 58X reluctor
• Standard 4.03″ bore forged piston sets (unless noted)
• Choice of Wiseco, CP, Diamond, or Mahle2618 forged pistons
• Oil and coolant plugs pre-installed

Important Notes:

• Optional upgrade to 1/2″ ARP head studs requires PRC aftermarket cylinder heads
• Gen III block uses LS1/LS6-style covers and components, but requires LS2/LS3 head bolts
• Expedite service may be available depending on parts availability

All TSP engines include 12 quarts of break-in oil at no additional cost for proper ring seal and startup protection.

Note: Custom rotating assembly options are available. Contact Texas Speed for an itemized quote and current build time.
