There are 8 plugs:
There are 2 plugs in the back of the engine were the transmission bolts to the engine. You will need to remove transmission or pull engine to fix those.
There are 2 plugs on each side of the engine just above were the oil pan bolts onto the engine. 1 on each side is hidden behind the motor mounts. There is 1 hidden behind the starter. The other one on the driverside you can see good.
There are 2 in the very front of the engine, 1 on each side of the timing cover and they are hard to see. Will have to remove a lot of stuff off the front of engine to get to those. And that makes 8. Caution If you do replace the 2 on the back of engine, the bigger plug in the CENTER of the block is a cam plug. Leave it alone, do not touch there is no coolant behind it. NEUTZ.

it now has a 305
== == In all honesty, the Ford 302 is a much better engine than the 305. The 302 will outlast, outrun, and out pull the 305. The 305 is GM's joke engine. I am a mechanic and GM will sorely suprise you. Cheap quality. Ford all the way. I used to be a Chevy guy, until they ALL tore up on me. Have had 2 Fords since then, and all I have had to do is change the oil, spark plugs, and air filter. I have the 302, MAN is it an awesome engine. Have had the 305 and it's towing ability is very sad. == == == ==
