Potential 360 build couple of questions

At this year's Carlisle, there was a give away engine built by Muscle Motors. They used a pre-Magnum roller cam block. It was 408" with RHS LA heads, Air Gap, Holley Street Avenger and a Comp XR286 cam which is a hydraulic roller grind. Simple build really. Sounded nasty with Shoenfeld dyno headers on it. Made around 440 hp and about 500 ft. lbs of torque.

Not sure what your goals are but it seemed like a decent, inexpensive street combo to me.

Linky here.
