Mopar engine differences

I always have apppreciated people who are new to the Mopar family and ask relevant questions. The Mopar engine families have pretty much led or followed the lead of other manufactorers. Most answers in this forum have been informative, particularly the difference in a long block or short block. Standard of the industry. Mopar small blocks (LA) were listed in cubic inch displacement from 273-360. and all did have rear mounted distributors. The term "big block Mopar" can refer to all the engines people mentioned from 350-440 cubic inches with front mounted distributors. From this group, you could also have B or (Low Block/deck height) and RB (Raised Block/deck height. That is basically the 3.31 stroke vs 3.75 stroke. Another significant difference that most people take for granted is the deep skirted crankshaft placement within the confines of the B or RB engine. This contributes significantly to strength and weight differences from A blocks vs B and RB blocks. All great engines. Great question.
