496 to be DYNO'D!

Well my guess from after talking to mark is that your running an ISKY hyd roller. Thanks for clarifying the fuel pump for me, wanted to be sure I had the right one. As far as the timing goes, a street ride should definitely have the vacuum advance hooked up. However its his motor and the fella who built it for him is more than knowledgeable. If I were guessing, its still timed exactly how it came off the dyno. Just be sure mark knows that your driving this thing out on the street! That little bit of info needs to be relayed to the builder.
