Sorry Frank but you are1 year off. The first full year for the bridge over 
rockers on the largerV8 heads was 1974. The 73 year castings for the most 
part were screw in studs.?That is not to say that when production change 
over started, there were not some late 73 360s or 401s that got the 74 head 
with the bridge set up. The 304s on the other hand got the bridge overs 
earlier than the
360-401 head.That maybe why you are seeing something in a 73 manual with a 
bridge over rocker"

What I am trying to do is establish a possible timeline on bridged rockers. 
I have always thought that they first appeared in 1974 (production) but 
occasionally I get something here that simply baffles me and the engine here 
is one, which has never been apart. In case the craigslist ad goes dead here 
is the information:
"AMC AMX 401 engine, intake to pan. 612Z05 valve cover tag, Date code built 
December 5th, 1973. Original high volume waterpump AMC part number 3215719. 
AMC heads 3220502-1. Was coupled to a AMC Torqflite 727, date coded 7-73 
(July 73). Has 4 barrel intake, forged steel crank, distributor, and one 
dogleg exhaust manifold attached. Autolite Motorcraft AMC 4 barrel 
carburetor available for $100 more. Bring a engine hoist & truck, will help 
load. $1100 firm. Also have 390 68-69 bare block $700 & 73 401 engine short 
block with forged steel crank, 7 pistons & rods $600. Need more information 
call 713-four-6-four-8825 days. West Houston, search PLANET HOUSTON AMX."

I had a customer ask me about it, actually several but all seem as confused 
as I am about it. The valve cover, flexplate (currently on ebay, but might 
stop auction) heads, everything original as never been apart, and been 
stored for years.
