The GM A and G-body cars are some of the most liked and sought after cars of the muscle car era and beyond. Engine swaps are common
,
many of these cars came with inline 6
cylinder and
small V8 engines. While these engines can be
good
performers, many times a larger or modified V8 engine is used to replace the original powerplant.

{{Note1}}The metric G-body was actually classified as an A-body from its inception in 1978 all the way through the 1981 model year.
The '78 -81
cars are sometimes listed as A-bodies as a result, but are actually G-bodies.

But these days (ca. 2012), unfortunately, budget considerations often take priority over the desire to have a numbers-matching and/or correct restoration. And there are those who are not into the whole numbers matching deal and could care less who thinks what; it's their car, they're paying the freight, and they feel the right to build their car the way they want not what someone else thinks is "right".

If a GTO does not have the original engine, any later Pontiac (301-455) would bolt in. The 455 has gobs of torque and there are many aftermarket parts now available, including stroker kits. While some of the iron round port Pontiac heads are good performers, their cost is out of sight when compared to an aluminum aftermarket head that can outflow them while costing and weighing much less. The horsepower and streetability of the large Pontiac engines is impressive. They bolt right in, however driver side headers may need slight modifications. Some of the A-body cars are on the heavy side (G-bodies not so bad), so a larger engine is a big asset. A strong transmission like the TH400 is a very good choice if an automatic is to be used.
