For instance, if you want a flat top piston there is none available for a 200, but a 2.3L HSC Ford tempo piston is a high swirl flat top piston with the same 3.680 bore size as the 200. The only difference is the 2.3 HSC pistons have a .090 pin offset, and the 200 pistons have a .060 offset. However, they still work fine, and are available oversize up to .080 from Speed Pro. | For instance, if you want a flat top piston there is none available for a 200, but a 2.3L HSC Ford tempo piston is a high swirl flat top piston with the same 3.680 bore size as the 200.

When working on the cylinder heads on the older engines ( 1960-1968 ) the '60-'68 heads do not flow well. Replacement '69 up heads are better, particularly D8 and E0 casting heads, which would come in 1979-1983 model years. These heads have 1.75 Int valve/ 1.36 Exh which can be machined to 1.5. The drawback to these heads is the chamber size is 62cc, '60-'68 heads are 52cc, so compression drops approximately 1 point. There are also Australian cylinder heads with removable intakes that can be got, but they are expensive to get. There is an aftermarket version available from ClassicInlines.com | When working on the cylinder heads on the older engines ( 1960-1968 ) the '60-'68 heads do not flow well.
