Ready to choose your setup? Here’s what’s inside our 1300hp and 1700hp kits, perfect for drag strips or high-torque street builds:

Pro Tip: The 1300hp kit shines in boosted LS3 builds for street/strip cars, while the 1700hp kit is a favorite for all-out drag racers with LS7 blocks pushing big turbos. Check your block’s bore (e.g., 4.125" for LS3, 4.185" for LS7) before ordering to ensure a perfect fit!

Assembly Notes: These kits demand a skilled engine builder to set bearing clearances and ring gaps for your specific setup (naturally aspirated, turbo, or supercharged). We aren’t liable for damage from improper assembly or incorrect clearances.

Sales Policy: Rotating kits are custom-ordered and non-returnable. All sales are final, so double-check your build specs before you buy!
