Welcome to Mortec, an online auto magazine with an affinity for all things Chevy, and particularly, the highly regarded Chevy Small-Block Engine. Whether you are an engine builder, drag racer, circle track racer, boat racer, road racer or a hobbyist doing a classic Chevrolet restoration, Mortec has information you can use, starting with our ever-popular Chevy casting number lists for small-block (SBC), big-block (BBC), and 348-409 V-8 engine blocks, cranks and heads. We have detailed instructions about Chevy casting number locations and extensive notes about Chevy "mouse motor" and "rat motor" V-8 engines. Mortec also has information on Chevrolet V-8 bore and stroke numbers, GM crate motors, Holley carb tuning tips, and crankshaft journal sizes.
We are constantly adding new engine codes and auto parts to the site. In 2012, Mortec launched free car mechanic forums, staffed by seasoned auto technicians with unmatched experience and a passion for helping fellow users. If you are driving a Ford, Mopar, one cylinder Junior Dragster, motorcycle or a boat, don't worry, there's still information here you can use. If you don't see what you are looking for, drop us a line in the forums, and we'll be glad to help.
