304 V8

Is there a different in the years of the 304 V8 1971 to the 1972? Also has a automatic trans.
I'm getting a commando with a cj front but has the commando frond end and hood. Also is parts easy to find! I'm in PA

 

Seem to recall some differences in valve train, cylinder heads, rockers arms/studs etc.

 

Careful - the '70-71 engines had a flat crank flange, different from the later engines. Not sure how much that affects, but I believe they are not bolt-in compatible. Search the Wagoneer forums if it's an issue. Specific questions about the transmission? It's a nailhead TH400, and the '70-71 flexplate and convertor are likely different. Look at the '65-73 J-series parts book on the Tom Collins site for changes in these parts. The J-series will be the same in this respect.

Anything but routine service parts for a Commando can be difficult to impossible to find.

 

Thanks

 

304 parts arent difficult to find if you can wait a day or three. Over the counter availability can be hit and miss though. NAPA alway able to help me, though almost always need to come back when stuff arrives.

I think your rockers will be the same. Switch to inferior bridge rockers happened early 73, IIRC. For sure my June 73 had bridges.

I just took down two 304 (73 and 77). I'm rebuilding the 73 and will have one left over crank. Both mic in spec and dont need a grind. If you want a crank I have one. Fresh out of engines, not half rusted door stops.

 

I found out that I have a 360 not a 304 The PO must have swapped the engines. Thank you! I need to find body panels for the commando any good resources.
