Editing Chevrolet crate engine components and modifications

From the early days of Target Master crate engines to todays (ca. 2012) crate engine selection from GMPP that are many and varied, the engines have progressed with the tinmes and are a good value for a new engine wityh a warranty. ==Modifications== Some of the better values are the base crate GMPP engines. However, the camshafts can leave a lot to be desired. Because of that, often the first thing to be changed is the cam. There are a number of tests done by Chevy High Perfornmance magajine that can be seen [http://www.chevyhiperformance.com/sch/02/gm-350-crate-engine-build/articles/index.html here]. ==Parts list for the SBC 350 HO part number 12496968 Deluxe crate engine== Crate Engine Service Parts List (all parts are supplied by GM unless otherwise noted) '''Partial Engine Components''' Part No. Description QTY 10105123 Block, 4-bolt main, cast-iron, 1pc rear seal 1 14088526 Crankshaft, Nodular Iron 1 10120990 Crankshaft Main Bearing std #1 thru 4 4 12528826 Crankshaft Main Bearing std Rear 1 12561388 Main Cap Bolt, Outer 7/16"-14 X 3-11/32" 10 3877669 Main Cap Bolt, Inner 7/16"-14 X 2.06" 6 12561389 Main Cap Stud, Inner (windage tray mtg.) 7/16"-14 X 3.3" 3 10088158 Crankshaft Rear Oil Seal 1 14088556 Rear Main Seal Retainer 1 12555771 Rear Main Seal Retainer to Block Gasket 1 14080362 Rear Main Seal Retainer Stud 2 10243247 Crankshaft Front Oil Seal 1 10108688 Connecting Rod 8 12523924 Connecting Rod Bearing, std 8 461372 Connecting Rod Bolt 16 225854 Connecting Rod Nut 16 12514101 Piston 8 88894219 Piston Ring Set 8 12453170 Camshaft Bearing std #1 1 12453171 Camshaft Bearing std #2 and rear 2 12453172 Camshaft Bearing #3 & #4 2 10241154 Camshaft Plug Rear 1 88891749 Freeze Plugs 8 1453658 Trans Locator Dowels 5/8" X 1-3/16" 2 12554553 Timing Cover Dowels 1/4" X 5/8" 2 14081701 Oil Gallery Plugs 1/4" NPT 4 14084945 Coolant Drain Plug 1/4" NPT 2 585927 Cylinder Head Locator Dowels 5/16" X 9/16" 2 '''Valvetrain Components''' Part-No. Description QTY 24502476 Camshaft 1 5232720 Lifters hydraulic flat 16 14095256 Pushrods General Motors 16 10089648 Rocker Arm, stamped steel, with ball & nut 16 3814692 Rocker Arm Stud, press-in style 16 12557390 Rocker Arm Nut 16 10212811 Valve Spring 16 24503856 Valve Spring Keepers 32 12564852 Valve Seal Exhaust 8 10212810 Valve Seal Intake 8 10241743 Valve Intake 1.94" 8 12550909 Valve Exhaust 1.50" 8 14087014 Timing Chain 1 340235 Camshaft Timing Gear 1 2436162 Camshaft Timing Gear Bolts w/Washers 3 10128346 Crankshaft Timing Gear 1 141215 Front Timing Cover (sheet metal w/o pointer) [Proform] 1 141202 Timing Pointer, Chrome for 8" Damper [Proform] 1 10108435 Front Timing Cover Gasket 1 11561767 Front Timing Cover Bolts 10 '''Cylinder Head Components''' Part-No. Description QTY 12558060 Cylinder Head w/valves, cast-iron,Vortec 2 10105117 Cylinder Head Gasket 2 12495499 Cylinder Head Bolt Package 1 141107 Valve Cover 2 per package [Proform] 1 66035 Valve Cover Beather [Proform] 1 141630 Oil Fill Cap [Proform] 1 141615 PCV & Breather Grommet Kit [Proform] 1 10046089 Valve Cover Gasket 2 12338092 Valve Cover Bolts 8 6487779 PCV Valve 1 '''Oiling Components''' Part-No. Description QTY 12555284 Oil Pump w/0.620" dia. tube hole 1 3855152 Oil Pump Pick-up & Screen w/0.620" tube 1 93442037 Oil Pump w/0.742" dia. tube hole 1 12550042 Oil Pump Pick-up & Screen w/0.742" tube 1 '''Special Note:''' Both the 0.620" and 0.742" oil pick up tube diameters are used depending on avaiablity at the time of engine production.
