This is the first time I'd seen these heads. I figured the engine would make 850 hp since the compression wasn't that high and the cam was an off brand. But when we opened the throttle the engine started to howl and the needle spun on the HP gauge.

Funny thing about this engine is that the customer who brought it in bought it at the track from a guy who was pissed at poor performance. Guy was so mad he sold the engine for $10K at the track. Probably cost close to $40K to build an engine like this with all new parts.
