    pulleys

    Did all five engine options in 58 use deep grove water pump, crank and generator pulleys? I see in the 5th edition judging guide says all engines used the 328 pulley but does not list water pump pulley number. I assume since it is deep groove the rest would be also. Am asking for a friend who is restoring a 245 HP 58.
    Thanks for any info.

    There were two sets of crank and waterpump pulleys used for 1958. Early 1958 used crank pulley GM #3742991 and waterpump pulley GM #3713974. Later 1958 used crank pulley GM #3756328 and waterpump pulley GM #3724816. These applied to all engines and as far as I know, all were "deep groove" (i.e.1/2" groove width). Just when the change-over occurred during 1958 PRODUCTION, I do not know.

    As far as generator pulleys go, 1958's with high lift cam engines (mechanical lifters) used pulley GM #3711685. This pulley is 4" OD and has an attached fan. All other engines used pulley GM #3750535. This pulley is 3-5/8" OD and has an attached fan. Both pulleys are "deep groove" (1/2" wide)
