Another engine build finished up today and is ready to make some noise. We built this 302 Ford for a derby application and it will be put to work! 🔥

This one received an overhaul including replacing a broken block, our derby application machining/assembly process, and a complete service on the heads including an all new valvetrain along with our cam and lifter combination.

Making some noise in the shop today! 🔥

This 455 Pontiac is fresh out of the assembly room and ready to go to work in a 1971 Trans Am. Originally brought to us as a stock engine, we gave it a complete overhaul and stepped things up with a full roller valvetrain and an Edelbrock CNC-ported cylinder head setup. This one should grab attention cruising down the street.
