Ok here goes.
old set up...302 2v heads, 650 holley, stock 4 bbl intake, headers, 2"exhaust, crane cam 218/230 @.050 w/488/498 lift, 4 speed and 3.00 rear end.
New set up. Same bottom end, carb and intake. Now has 4v heads so a little more compression, 2.5" exhaust, and comp cam 230/236 @ .050 w/520/523 lift. Same trans and rear gears.
Ok, so why is the car slower now than before? I'm thinking the rear gears. If so why would the car be faster with, say, 3.55 gears with the new set up as opposed to 3.55 gears with the old set up? Hmmmnn Thanks in advance for any answers or ideas.
