RE: Common problem with budget pistons.

By Ted E. - 07/12/2003 11:14:33 PM; IP 63.80.24.38

Most pistons have available the build specs (usually in the catalogue) which lists the compression height or the pin location. With this information, it's very easy to know exactly where the piston is going to sit in the bore in relation to the deck at top dead center before ever buying the piston. Of course you'll measure your block's deck height and rod length prior to doing any actual ordering just to insure that the deck is where you think it is and the rods have not been abnormally shortened by resizing. If ordering custom pistons, you'll definitely want to do this.

For the 390, there was originally a variety of pistons with different wrist pin heights to vary the compression ratio without changing the heads or to accomodate different head gaskets. Knowing that different pin height locations are available on the stock replacement pistons allows you to selectively pick a piston specifically to suit your needs without necessarily buying custom pistons.
