Steel 4-bolt center main cap for large bore engines (not 'S'). Comes with correct length HT bolts. For center cap without grade 8 bolts see part 619-CTR.
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.
Bolts on one way only so take care to read instructions.

FITTING INSTRUCTIONS

This cap has to be line bored and thrush washer faces machined before use. It is uni-directional and must be fitted with the ‘F’ stamped in one side facing towards the front (water pump end) of the block. This can be confirmed by checking that the end with the least material between the outer bolt hole and end of the cap is facing the dipstick side of the block. All bolts should be torqued to 65lb ft, DRY threads.
