4.6L / 5.4L 2V PI - NPI Blower / Nitrous Camshafts

Once under heavy boost and/or nitrous the various heads and shortblocks need close to the same cam specification. The larger big bore, stroker, and 5.4 based engines can use the next size cam bigger than a 4.6 based motor. If you look closely the exhaust centerline has been advanced considerably to help blowdown the cylinder and release as much heat as possible. Stage 1 and Stage 2 cams can use the stock springs, all larger cams require upgraded springs.

Please contact us if you have any questions on choosing the correct cam for your application.
