SBM March Crank Pulley 10051
Got a nice March Crank pulley for a SBM. Now its the smallest one they make at 5 1/4 inches. My old 318 was throwing the P.S. belt at 7,000 rpms, lol. This pulley stop that but motor temp was creeping up at the stoplights. Did not want my new 340 to run 200 degrees at the lights so got a 6 3/4 pulley. I was using a 6.7/8 water pulley, a smaller water pump pulley might work out great ???
One bolt hole I had to enlarge. My new 6 3/4 pulley was done right. This was brought from Summit last year! http://www.summitracing.com/parts/MCH-10051/
Price, hmm. $40 total to your door lower 48 states
I'm in S.E. Michigan and on ebay as 1572Peters
