NOVEMBER 2019 II CHEVY HIGH PERFORMANCE 19
01 | The beginning of any factory-block-based 383
build inevitably involves some time spent with a die
grinder. Note the small notch needed at the bottom
of the cylinder bore. This is to clear the head of the
rod bolt.

performance. Each top and second ring was gapped and checked in the bore with a feeler gauge. The gaps
were set based off the specs included with the SRP pistons.
04 | Next, the SRP pistons, which are a hearty
forged 4032 aluminum design, were assembled
with the Scat H-beam connecting rods and ARP rod
bolts. This is a very stout combo ready for anything
this engine can throw at it. Full-floating wristpins
are slid into place and retained using Spirolox rings.05 | Next, the rings are installed on the pistons and they are neatly arranged
in preparation for assembly. A light coating of 20wt engine oil is used to lubricate
the rings and pins before assembly.
06 | The block, which was thoroughly cleaned after clearancing for the stroker
assembly has the rear main seal installed as well as the upper shells of the main
bearings. A slight dab of sealer on the rear cap pad and a coating of assembly
lubricant prepares it for the crankshaft.
