Does your engine run like a dream or a nightmare?
Achieving that classic muscle car rumble under the hood is what most of us are after, but too much of a good thing can be make an engine a nightmare to tune. With a very wild camshaft profile the engine can’t complete the entire combustion process so with the valves are still open, this causes a backfire effect into the intake runners which doesn’t necessarily create more power. Engines need at least 14-15lbs. vacuum to run power brakes, with today’s more efficient hydraulic roller camshafts this is achievable to make great torque. Good idle quality and crisp throttle response. Whenever you’re at the fence with a choice between a smaller or larger camshaft we recommended always going tamer especially for a cruiser. Engine Factory has a selection of camshafts that are setup with matching components – Cylinder heads, compression, pistons, induction and the list goes on. Having the “right” amount of lope but still have ample vacuum to run accessories is the ideal situation.
