A new crate engine can awaken your 1969 Mustang's performance and transform how it drives. These complete, pre-assembled engines bolt into your '69 Mustang for a power upgrade. Crate engines provide big gains in horsepower and torque over the stock motor. Yet they still maintain reliable daily drivability. You can choose an engine to match your desired power level and budget. Be aware that some crate engines or swaps require supplementary hardware or components like an intake manifold or distributor to run properly.

If you'd rather build an engine yourself, aftermarket cylinder blocks make a great starting point. Aftermarket blocks designed specifically for the '69 Mustang tend to be stronger than stock blocks. This extra strength allows for a higher compression engine with more aggressive camshafts for maximum power. With an aftermarket block, you can construct a rugged, high-revving engine tailored exactly to your performance needs.
