Stroked 318 power

niceolddart said
I just watched an episode of Nicks Garage where he dynoed a 318 stroked to 390ci. Factory cast iron exhaust manifolds, factory iron 587 heads, 750cfm (I think) carb & .425ish lift flat tappet hydraulic cam with 10.5 compression. It made just over 400 h.p. & 440lbs torque! Pretty good stuff.

it's not bad but if you look at the 380hp crate basically has the same power curve at the same rpms and that's just a 5.9l with cam headers and 4 bbl.
