So there's been a lot of talk online about how heavy (or unrealistically not heavy) certain engines are. When I tore my 302 apart I figured I'd bust out a few scales and weigh some parts so we'd know the facts about at least one engine.
It's a cheapie bathroom scale, but it reads me as being the same weight as the scale from my recent doctor visit, so I'd say it's fairly accurate (at least accurate enough for this application)
Lets start with the block - 105lbs
Then there's the rest of the shit I'm weighing
Crankshaft - 35lbs
Flywheel/PP/clutch - 38lbs
Harmonic balancer - 8lbs
Main caps - 7lbs
Starter - 6lbs
Water pump - 6lbs
Power steering pump + bracket - 5lbs
Timing cover - 2lbs
Alternator - 11lbs
Carburetor - 5lbs
Oil Pump - 2lbs
Distributor - 3lbs
Camshaft - 8lbs
Intake manifold - 17lbs
Exhaust manifold - 2 x 4lbs
Oil Pan - 5lbs
90* oil filter adapter - 1lb 3oz
Timing chain + big gear (plus small gear exceeded weight limit of scale) - 2lbs 6oz
Small timing chain gear - 9oz
Crankshaft pulley - 2lbs 3oz
Alternator bracket - 2lbs 3oz
Rod + piston + rings + rod bolts - 8 x 2lbs 7oz
Fully assembled aluminum heads - 2 x 32lbs
Valve covers - 2lbs
Spark plug wires - 1lb 13oz
Just finished crunching the numbers and came up with 369lbs, which at first does seem a bit low, but I double checked my answer and it came out the same way both times. The only things I can think of that I didn't weigh were the head bolts, lifters, pushrods, mounts, other fasteners and fluids... lets call those a very generous 31lbs, bringing us to a total of 400lbs. Regardless of the transmission you use (t5 or TKO) you'd still be under 500lbs, which is interesting, because
which would mean the 302 practically doesn't have a weight penalty when swapped into a m20 car. Wish I knew this when I still had my car
