81 Clutch components



Hello all,

I have a new engine to put in my 81, its the GM 330 horse 350 crate engine. I have been getting another order ready for the installation, and I have some clutch questions. I have many shop manuals and catalogs, but I have not nailed down for sure exactly what spline, clutch diameter, and flywheel diameter is in this car.

I know the flywheel I need for the 3 inch bolt pattern crank, but I was surprised at the number of different clutch and pressure plates offered for an 81. Anyone been here already?
