Here’s what makes this short block a powerhouse for your next LS7 project:

Build Tip: This short block is a go-to for LS7-based drag cars with big turbos or street builds craving instant throttle response. Confirm your block’s 4.125" bore and dry-sump setup for a seamless swap. Pair it with high-flow heads for max power!

Assembly Notes: Built with precision, this short block has bearing clearances and ring gaps pre-set for 1700hp applications. A skilled builder should verify fitment for your setup (turbo, supercharged, or NA). We’re not responsible for issues from improper installation or modifications.

Sales Policy: Short blocks are custom-built and non-returnable. All sales are final, so ensure it matches your build plan before ordering!
