I used to race a 350 powered Vega and it was built to run so it had more clearance, I used straight 50 weight back then and NEVER lost an engine or scuffed a bearing. However, once when the oil pump pickup fell off the engine starved at 8000 rpm, damn, what a mess that was getting that 50 weight off the track. |
