Upgrade your Ride / Powertrain & Fuel Delivery
Crate engines, fuel injection and fuel systems. Kits made for your car first, then universal parts that fit most cars, and every maker we track.
The engine and everything that feeds it: a modern crate engine (GM LS or LT, Ford Coyote, Gen III HEMI or a fresh small-block), fuel injection that replaces the carburetor, and the tank, pump, regulator and lines that EFI needs.
Fuel injection starts on a cold morning, idles in traffic, adjusts for altitude and uses less fuel than a carburetor. A modern crate engine adds power and reliability, often with a warranty. EFI runs at much higher fuel pressure than a carb, so the fuel system is part of the job: an in-tank pump or EFI-ready tank, the right regulator and lines rated for it. Plan the engine, EFI and fuel system together.

Build guide, C1 Corvette
The Summit cart for our 1961 Corvette's LS swap came to $14,507.87, and it's missing a few things. Here's the full list, what we found and what it really costs.
Comparison
A Coyote and manual is about $17,000 new before the clutch, or around $12,000 used from a late Mustang. Prices and the fine print, October 2026.
Comparison
The 5.3 is cheap new or used; the LS3 is where a used pullout saves $10,000. Prices, part numbers and the catches, checked October 2026.
