LS swap cost estimator

Build a realistic LS swap budget line by line. Defaults come from our sourced parts lists and catalog medians; change any number to match your quotes.

Start from a sourced parts list (optional)

Engine (junkyard pull, used or crate)

Transmission

Mounts / swap kit

Oil pan

Wiring harness & ECU/tune

Fuel system

Headers & exhaust

Cooling

Driveshaft

Labor (if not DIY)

Misc (fluids, fittings, gaskets)

Contingency (%)

Where the defaults come from

Mounts: median listed price of LS swap mount products in our vendor catalog ($202).
Oil pan: median listed price of LS oil pans in our catalog ($500).
Sourced parts lists: the sum of required parts with prices in our vehicle swap guides (not a full budget).
For reference: Ford Performance 5.0 Coyote crate (M-6007-M50C) $10,225; 475 hp 5.3 LS crate (Speedway article: "a touch over $5k") $5,000.

Contingency covers what everyone forgets. 15% is a common planning rule; raise it for older vehicles.
