Hey, I have a 51 M37 and I was talking to a guy who has two m37. He swares that the M37 was made to only travel 35 MPH... He said he was trying to drive his 40-45 and blew the motor. Is this true? Also, I really need closeups of the dash of a correct M37. I think mine has been modified a great bit and I would like a guide to know how to correct it. Thanks!
