I just pull the 302 out of my 68 and there are a couple of things that I'm not sure is right. All the numbers match but at one time in its life it was disassembled. On one side of the motor the external head bolts do not have washers, is this right? The heads have screw in studs, is this correct? What's the best replacement clutch for this stock engine? Didn't really want to spend the money for the center force if thats over kill for the stock engine. Thanks
Usually the first thing to go on an original Z-28 302 motor was the valve springs!!
I bet whoever had the car before you way back when it was fairly new bent a valve or even several on one bank and freshened that side up and added screw-in studs but probably only had enough washers to do a partial install on them for who knows what reason??
I would strongly advise not going with the Centerforce Dual Friction on a 302. You will be very pleased with the Centerforce 2 model. The Dual Friction is a little too aggressive for a low torque 302. Probably better for a street and strip 383 though.
Just one 302 with a Centerforce DF drivers opinion.
