Quick video of us testing out the new Pontiac 461 stroker in Jordan's 1968 GTO. We'll have some better videos coming soon, but we couldn't resist playing around a little last night. Once again, this is a Pontiac 461, built using the original, numbers matching, 400 block. It has an Eagle 4.25 stroke rotating assembly, with forged rods and Mahle forged pistons, all from Butler Performance. It's also topped with a set of Butler Performance custom built, CNC-ported Edelbrock D-port aluminum heads, with 2.11 IN/1.77 EX stainless Ferrea valves. Finally, it also features a Comp Cams hydraulic flat tappet cam, with double valve springs specially selected by Butler.
