Proformance Unlimited now offers custom built Chevy EFI performance crate engines. These fuel injected crate engines are sold as complete drop in ready units. That are designed to replace any small block Chevy carbureted engine. These engines also work very well in your kit car project. We can also custom design these engine packages for use with stack fuel injected intake manifolds. Purchasing one of our turn-key fuel injected engines has many advantages for the engine installer such as no dyno-tuning required. All our efi engines are “plug & play”.
