not "three fourths". A "three fourths" cam would only work

"4L60"; As far as I know, it's just a new name for
the 700R4.
"balanced"; One of those over used and under
defined terms. It could include items like matching the weights of the rods and
also the pistons. Normally, it's used when talking about balancing the rotating
mass, it other words, the crankshaft. What you will never hear is the accuracy
of the balancing.

engines range in displacement from 396 to 502. They are all (for the most part)
the same size outside. Yes, you could make a 502 look like a 396.
"Blueprinted"; I really hate this term! It has to
do with making the dimensions of the parts in the engine more accurate (and
closer to the blueprint values). What you will almost never hear from the
average joe is what values were used!
"BTDC"; before top dead center

"CFM"; This is a carburetor term and stands for
"cubic feet per minute". It's the volume of air (over time) that the

the door windows. A sedan has a frame that's mounted to the door. As an
example, a 70 Chevelle is a "coupe", a 64 Chevelle is a sedan.

the firewall. On a Camaro, this should include the fenders, hood, radiator core
support, bumpers, etc.
