4-Bolt Center Main Cap 1300 A+ Type Only With Bolts
Steel 4-bolt center main cap for large bore engines (not Cooper S blocks). For center cap with included grade 8 bolts see part C-AGA619.
On all performance A series engines it is essential to ensure as accurate location of the center main bearing of the crankshaft as possible. Flex allowed here, especially at sustained high RPM levels, can cause spun bearings, crank or main cap breakage with severe or mortal damage to the engine. This specially machined cap provides the ultimate center main location, essential for all stroked engines.
Requires line boring, and two extra holes drilled into the block and tapped 3/8" UNF. The thrust faces are part machined for final finishing while the line boring is being done.
