383 stroker

[Init2winit]

Here is an all motor, pump gas "stroker" engine that I built. It has a very mild camshaft (.574 lift), and is very streetable. This was on a chassis dyno in front of an automatic, so figure about 15-20% drivetrain loss. It was having some carb troubles on the baseline, but you clearly see the end result. Also, look at how flat the hp, and tq curves are. The peak power was made at around 3500 rpm. This engine put up against one that makes the same power at higher rpms will run circles around it, for obvious reasons. 555hp/490tq
