Cylinder Heads
Mark IV cylinder heads, made by Chevrolet, will not interchange to a stock, production Gen.V Chevy block. There will be a water leak into the lifter valley because of a mismatch of water jacket core holes. Likewise, stock production Gen.V cylinder heads, made by Chevrolet, will not interchange onto Mark IV block cases for the same reason. There are exceptions. You can put Mark IV cylinder heads on a Gen.V “Bowtie” block because the Gen.V “Bowtie” cases have smaller Read the rest of this entry »

Moroso Crankshaft Wipers are designed so that they can be trimmed to fit the widest possible range of counter-weight, rod/stroke configurations. They are to be mounted to the starter side of the block only. The Moroso Crankshaft Wiper is engineered to clear assemblies down to 2.9 IN. of stroke using stock type rods. As the stroke is increased and /or larger rods used, the amount of material to be removed increases. Do not be alarmed at the amount of grinding and trimming with shears which may be necessary to clear your particular assembly. We recommend.030” to .045” clearance around all moving components. After you have trimmed your wiper, be sure to smooth all edges to prevent all potential engine damage due to burrs vibrating off into the crankcase. Before final assembly, double check for clearance when the crankshaft is rotated a full 360 degrees. Be sure to account for “thrust end play” while checking for proper clearance. After final fitting and deburring, cement the wiper to the block. You can use contact cement or weather-strip adhesive (An alternate method would be to use tiny flat head screws or pinning). Next, install the pan gaskets in the usual manner. Due to the slightly increased height on one side,
Be sure to use a dab of silicone in the corners where the rubber ends meet the side rail gaskets.

First remove the old cam bearings. Start by inserting the Black Drive Cap with the CD- ring into in the end of the Arbor you will tap with a hammer – in this case the end nearest to the permanently affixed Drive Mount. Slide the Black Drive Spool onto the Arbor, followed by the Red Spool Stabilizer, as shown in Fig. 1. Then proceed with removal of #1 bearing, tapping with a 31b miminum brass or lead hammer (steel hammers may damage the ends of the Arbor). Then reposition the Black Drive Spool and the Black Drive Cap onto the other end of the Arbor to remove #2-3-4-5 bearings, with the Blue Spool Stabilizer positioned as show in Fig. 2.
