Chartoo Posted March 18, 2008 Share Posted March 18, 2008 hi all I took of my sump of my 1976 260z the other day for the first time and when i was looking a the crankshaft i notice a few big drill holes in it. That means its balanced crankshaft yeah? So i was looking a the numbers on it to see if it was the orginal crankshaft or a different one. It has the numbers " 33-1" next to the nissan symbol and a larger "30" down ther also. does anyone know if this is this the standard crank?

ezzzzzzz Posted March 18, 2008 Share Posted March 18, 2008 Probably its a stock crank. Those holes are found in every crankshaft from factory balancing. Quote Link to comment Share on other sites More sharing options...
