Default Can old Pontiacs perform like LS motors?
I am amazed by the power, fuel economy and driveability of LS motors. Why can't we do this to a legacy Pontiac 400 motor, similar to an LS3 crate engine:
>300cfm heads
cam: low 200s duration @.050, .550" lift, 117 LSA
fuel injected
Well over 1hp/c.i. and 20mpg, trans gear ratios not-withstanding.
