square 4 twin pipe alloy motor

Postby william shortall » Thu Oct 15, 2020 1:43 pm

Could anybody please tell me the standard crank size for a 1952 twin pipe alloy motor .The engineer has asked what the sizes they are as standard
I have bought new rods and shells from the club and now the job is about to begin on the engine as the rolling chassis has been done for some time but covid put a stop to the the engine work Any information would be grateful

Dragonfly mention in there fact sheet that the timing side journal is 1.250.
