We also recommend ZDDPlus with each oil change. It is critical that a new camshaft and lifers are broken in with oil containing ZDDP or the use of a bottle of zink additive. While this is fine for late model engines using roller lifters, but in our older flat tappet applications, the elimination of ZDDP will result in rapid and severe camshaft and lifter wear. Please note: Zink additive (Part Number 14-346) listed below must also be used for proper cam and lifter break-in.įor emission reasons, most oil manufactures are reducing or eliminating Zink Dialkyl Dithio Phosphate from their domestic products. 040 with pistons, mild cam, stroked (3.58) crank with new rods, remanufactured for high lift Vortec heads, aftermarket Vortec intake, gaskets - pretty much everything but the carb (was going to use the current 4bbl in the car). This high pressure, moly-graphite assembly lube is required when installing new cam/lifters. For a separate fee of 1700 there is a disassembled 4-bolt 350 bored. 39 degree bank angle.Ĭorrect special fuel pump eccentric/timing gear to camshaft bolt.

The wide LSA ensured a friendly idle quality, while the added lift and duration all. 480 lift, a 212/218-degree duration split and a 114 degree LSA. Designed for computer-controller Magnum engines, the Xtreme Energy XR262HR cam offered. This is the same cam we use in our 67 4-4-2 Super Pro ET Bracket Car. With low-speed torque and a daily driver in mind, we chose a mild, but plenty powerful grind from Comp Cams. Will pass NHRA tech for stock eliminator. This cam is just plain nasty sounding! Produces outstanding horsepower and torque to 6000 RPM. Use with 4 speed, or automatic with 3500-4000 rpm stall converter and 4.10 or lower gears.

Based on a 107 degree lobe centerline, this cam features 243 degree intake duration and 262 degree exhaust at. This is a brand new duplicate of the factory 328/348 'cheater' cam used by several record holding 455' drag race stockers. You should be able to make a 300hp/350ftlb of torque with that 350 with a mild cam and some mild head work. Good for 20 hp more on stock GM smogger heads. CamshaftĤ55 72 4-4-2 AT all including W-30. If you can, pull your heads and do some minor bowl work and do a fresh valve job.
