408 Stroker

Just under 500 hp, with 600 ft lbs of tq as low as 2600 rpm. Edel RPM intake.

No, not a 408 Chrys, but a 455 Pontiac. These were impressive #s because the engine had factory iron heads & QJ carb. 10:1 CR, 236/242 @ 050 cam. Nothing very fancy.

I do not know how to link the page, but is on the PYOnline.com forum.
