I considered both a 408 and a 347 from Blueprint. I ultimately went with the 347 since it fits better in the engine bay of my 66 and what the 347 makes in terms of power is already at the edge of what my T5z can handle. I didn’t want to worry any notching shock towers, swapping the hood if the engine was to tall for my stock hood or blowing up the T5z right away. You may not have those concerns with a 68 though. My Blueprint engine is fantastic, I’d recommend an engine from them due to quality and customer service.
Had I built the car with a bigger engine in mind I wouldn’t have hesitated to get the 408.
