Running 15W-40 oil. Engine has not been rebuilt. It’s a 250 from the 60’s is all I can tell you. I was running at 51 MPH when picture was taken. I had this 41 rebuilt a few years ago. Originally had the stock 216 in it. Last year I swapped the 216 for the 250 after throwing a rod in the 216.
I definitely need to recalibrate the speedometer because it was running 10 MPH lower than what I was actually driving.
