ok guys need help, i have a 52 chevy 1ton truck 3800 series.my bely is squealing real bad. The crankshaft pully and altenator [i put altenator on instead of generator] is smaller then water pump pully. My friend thinks it is a 235 motor. all numbers says it is a 261 1954 motor. i really don't know but my question is where can i find a pully for 1954. and r the 235 and 261 same pully. here is a few pics of motorpullypullypully
