I have a 1976 C-20 with a stock 350, just curious what heads are on it right now? also pistons, and the stroke, bore, compression, etc. Thanks for any info.

Pull of the valve coers and get the numbers stamped on the heads. Then look at the block behind the drivers side head and get the numbers back there. Finally go to www.mortec.com and look up those numbers to see what you have.

Most likely 882's.

Anyone know where I can find a good set of 461's?
