I looked it up through www.mortec.com and found it to be a 1972- 1973 350 but, I could not find your exzact number I only found 3998920 so, recheck ur numbers cause that first 8 could be easily mistaken for a 9 on a motor that old.You don't know what you've got til it's gone

I tried rubber isolators between the frame and pump, but it made little difference. I don't mind spinning the motor over to refill the carb(s), it allows time to build oil pressure, jmho..
