The "Muscle Cars" of the 1960's and 1970's are a very distinctive American art form of the 60's and 1970's. 60's muscle cars are treasured by vintage and retro auto collectors of all ages and types. Some of these people perhaps could be said are reliving their past, others dreaming of the 1960's. It has been said about the era of the 1960's that if you can remember it then you weren't there. These muscle cars were often pre-existing even rather mundane autos pumped up with giant motors in the ranges of 400 cubic inches. Wow. Gas as fuel was cheap then so fuel costs were not a concern as is the case today.

All American auto makers were involved in muscle car production ' it as a great image to have and create. This article deals with the engines which powered the Chrysler and Mopar versionsChrysler large block engines gained the moniker of The "Big Boys" on the block or the "Big Blocks'. Internally in the Chrysler, Dodge and then Plymouth divisions these engine blocks were technically designated in shorthand as 'B" and "RB" base engine blocks.Chrysler B and RB engines are a series of very large in not gigantic engines block V8s which in the year of 1958 took the place of the Mopar designed 1'st generations of 'Hemi 'engines. Then in short step Flange bolts both the B and the RB engines made use of the specialized and whomp performing power plants - those with wedge-shaped combustion chambers.Next in line are the group designated secondly as the 'B' block engines. One might think that the 'B' designation signaled as second version as in group 'A' and group 'B'. This is simply not so. It was just the ongoing production designation. These overall have a 3.375 inches engine stroke. A variation of these B series was the 'RB' lineup of engines, which overall could of have been said to have been in full production through the years of 1959 to 1979. Essentially are told these are basically 'raised block' versions of the B engines.

All RB engines have a 3.75 inches stroke, with the bore being the defining factor in the engine size. Most noticeably as a well as characteristically the RBs are oversquare, yet it is an amazing testament to the Chrysler and Mopar design engineers of the time that the absolute extent of the engine purports that torque is not missing by any means. You have to remember that this was the pre-computer CAD aided design and testing era. Much of the engineering was if not calculated trial and error it certainly was in the minds and mindsets of a most exceptional group of design engineers and the associated engineering departments of Chrysler, Plymouth and Mopar. Much could have been said to be learnt and tested on race tracks across America often by the seat of the pants of engineering staff going out on the limb. It should be noted that the designation of the letter 'R' in 'RB' signifies raised, and that overall the RB series has a much more sophisticated deck than the B engine from which it was developed and descended from. It's all a matter of evolution along the path of progress and race testing.The 'B" as well as the "RB" perception are essentially comparable if not identical are uncharacteristically if not unexpected similar in both design and appearances Its like anything else in that those with training and expertise in any given field learn the tricks of the trade or at least whom to ask or contact by phone or email. Vintage automotive restoration experts can swap in a snap t a "RB" series Chrysler of Mopar power plant to take the place of an "R" and vice verso. This is what you pay for in real auto restoration professionals as compared to hacks and want to bees, True an RB block is grander and somewhat longer than its original model and prototype.
