In another thread I was talking about having top end oiling problems. Mainly being it wasn't getting oil. I've been doing research and I've come across the the '71/'72 years didn't have grooves in the spindles to feed oil. I think this might be the problem. I've read that you can have a machinist cut the grooves or get later year spindles. I was wondering if anyone has dealt with this or any recommendations. I live in Texas and I need as much oil cool the motor as possible.
