If a G-body does not have the original engine, any later Pontiac (301-455) would bolt up to a G-body frame. 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 G-body cars are on the heavy side, 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. | If a G-body does not have the original engine, any later Pontiac (301-455) would bolt up to a G-body frame.
