NEW 340 manifolds at a reasonable price

Yes, but look what they are working with.

Heads need to be the correct casting numbers

Intake needs to be the correct casting number

Carb needs to be the correct make and list number

Stock tires (11s on E70-14s for example)

Car needs to sound very close to stock at idle.

Ya,..ok heads like stated before are ported to the max,intakes also,exhaust manifolds power extruned,carbs tweaked to the max and modified,hugh roller cams,stroker cranks,rollerized transmission,some of those guys got upwards of over $30k in the engine alone..as for launching on bias-plys was told by one of the competitiors its not really that hard,plus they treat those tires with traction compound for an extended amount of time before an event..i get a good laugh when ever i'm at at the track and those cars are running people in the stands actually believe they're mostly stock..LOL...as for the header/manifold debate headers win everytime...
