About to put my truck back together. I need a few parts, namely a torque converter, flexplate and a harmonic balacer. Truck is a 78' with a 302 and a C4. Any input I to what i need to get is appreciated.

 

Flexplate is for a clutch. Perhaps you need a flywheel?

 

Nope Flexplate is for automatics. Flywheel is for a manual with a clutch. Your thinking of a pressure plate.

 

I stand corrected. I'll go stand in the corner now

 

I think summit and jeggs would be the easiest place to get all the parts you need and have choices for after market parts. I have seen thicker flex plates. I am going too order one for my c6 when I pull my truck down to do a few upgrades. The torque converter should be close to the same operating rpm of your cam.

 

There is room in the corner now that my wife let me out of it

 

Any idea of dampener and flexplate I need? How many teeth? External balancing? How many ounces?

 

Is the 302 original to the truck? If so, then you would want a 28 ounce imbalance flywheel/flexplate and harmonic balancer. The 302 changed to a 50 ounce imbalance spec in 1981 I believe.

The best indicator of what you have/need is the part number on the crank.

 

Yes its original to the truck. Appreciate the info.
