From mid-1933 thru 1936 'Master' & 'Standard' were used. Model names 'Superior K,' 'Superior V,' 'Capitol,' 'National,' 'International,' 'Universal,' 'Independence,' 'Confederate' and 'Eagle' were used prior to 1934. Most early wood-bodied models had this plate nailed into the seat frame or the floor on the passenger side.

Below is a more detailed description of the various changes relative to the year of build.Д®arly Chevrolet cars & trucks used Car Number Plates to identify where the vehicle was made, which month it was made, show the series and the number of the vehicle as it came off the assembly line. You might want to contact your Local DMV to see what the requirements are in your state. I have my 32 Chevy registered in Connecticut with the body build sequence number from the cowl tag.

Some states will agree to use the body sequence number on the cowl plate, others want to use the GM car number on the floor/seat frame and some will use the engine serial number. The Fisher body build plate was attached to the cowl and showed the body build sequence and other information as described below. The GM car number was nailed to the passenger side floor or seat frame not screwed. The more you know, the faster you'll go.This is all I have for you.compliments of Moose Let's start with the big differentiations, and then we'll break 'em down into the smaller variants. As for the future, the rumors from Detroit are true about the Gen V family of direct-injection engines. To break down this family of engines into categories beyond iron and aluminum blocks, we'll focus on cathedral versus rectangle-port cylinder head engines, the change from mechanical to electronic throttle, and then the wave of subtle variations such as variable valvetrain technology (VVT). Beyond this quick and easy delineation, recognizing the differences that separate an LS2 from an LS3, for example, become much more subtle, but the cues are there. The LS family was originally designed around an aluminum block that was almost immediately converted to iron for truck and SUV applications. To categorize the entire engine family, it's best to break them up into two basic divisions of iron and aluminum-block engines. From its modest 5.7L LS1 '97 Corvette beginnings, there are now dozens of different engine RPO codes that we will not even begin to list for the sake of our sanity and yours.

This was literally the next GM RPO code available for this new family of engines.

Since Gen III/IV contains way too many syllables, the shorthand version quickly evolved into the far simpler LS moniker that was shortened from the first Corvette engine that carried the RPO (regular production order) LS1. Knowledge, as the old saying goes, is power, and if you know more than the next guy, you can turn that to your advantage.ДЄ friend recently asked what the letters 'LS' stand for, and we related that GM referred to the overall engine family as the Gen III and, after a revision, Gen IV engines. Plus, we have some just-released photos of the new LT1 Gen V engine that will debut with the 2014 C7 Corvette. With the incredible variety of engines now out pounding the pavement, we thought it might be a good idea to chart this evolution with easy-to-use identification techniques that can be of benefit to the boneyard and swap-meet hunter. These changes represent much more than just expanded displacement and power.

But with this popularity brings questions concerning the natural progression of change that has accompanied this engine family's 15-year-plus production span. Ever since the first LS1-powered Corvette hit the streets in 1997, the LS engines have become synonymous with late-model horsepower and torque and have become the go-to favorite of engine swappers around the world. Since this magazine is in your hands, it means you're one of those forward-thinking car crafters who appreciates a powerful street engine and wants to learn more.
