"The Ford Model A" by George DeAngelis, et al., lists 475 lbs including clutch and transmission (Section 2, page 18 of 2nd Edition). "How to Restore Your Model A" Volume 7 (Shipping Data on page 125) lists the following net weights:
456 lbs for A-6000 engine
517 lbs for AA-6000 engine
350 lbs for A-6005 engine.
Insofar as I (Skip) could determine, none of the above specify whether this is the dry or wet weight, but I suspect it's dry.
Also, here are some weights extracted from various FordBarn posts (principally by Tom Wesenberg if I recall correctly):
473 lbs – engine, complete (w/clutch & transmission)
160 lbs – engine, short block (w/head studs & crank pulley)
25 lbs – cylinder head
19 lbs – flywheel housing
12 lbs – Pressure plate
63 lbs - flywheel
3 lbs – clutch disc
10 lbs – engine pan
3 lbs – dipper tray
3 lbs – valve cover
2 lbs – timing gear side cover
4 lbs – timing gear front cover
28 lbs - crankshaft
6-1/2 lbs – camshaft (w/nut)
1-1/2 lbs – piston (w/wristpin & rings)
Any corrections/additions would be appreciated.
