You can find compression ration calculators on the net. Do you know what type of pistons you have.

For a chevy 350 the std bore is 4.00 inches stroke is 3.48 inches head gasket is 4.1 bore and .041 compressed thickness. Rods a 5.7 inches.

Now the hard to find out info is the piston cc and the deck height. Deck hieght is how far down in the hole the pistons are at tdc.

Do you know what type of pistons you have?
Bottem end is bone stock from a 85 suburban . Im not sure what came stock.
