I weighed my engine and parts that I have in hand, and will pass them along
as reference for those interested.  The engine weight is not precise since I
used a 200 lb capacity scale, and I measured the weight at each bracket
separately while trying to maintain the engine level (it has a mount support
bracket at each end) After repeating the measurement a couple of times, I
think I got it within +- 5 lbs.  All lighter parts were differential weight
with calibrated 25 lbs on the scale to eliminate 'zero' error.

All of the weights, including estimates for parts I don't yet have are:

Engine w/ pump, alternator - 260 lbs
Water Pump/al housing (inc.)
Alternator 70 amp (inc.)
Air Pump (vacuum) - 8.0
Custom oil pan - 4.5
Custom Intake Manifold w/TB - 6.0   (Est)
Inconel exhaust Man/Muff  - 12.5
SS secondary muff/Exit pipe - 3.5
Mount brackets - 3.0
Main mount - 15.0
6 Coils w/bracket - 4.5
Starter - 12.0
Re-drive RD1A - 28 (est.; need to get weight from Tracy)
Radiator 1 - 6.0   (Est)
Radiator 2 w/fan - 11.0   (Est)
Oil cooler - 7.0   (Est)
Expansion tank - 2.5   (Est)
Fuel pumps/filter - 3   (Est)
Lines/fittings - 7.0   (Est)
Coolant - 20.0   (Est)

Total - 414.0 lbs

Before deciding on this engine, I had guestimated 420 lbs, all up.  Looks
like I'll make it.

Is there a lighter starter?  This is the one I got from Atkins.

The 13B starter is 7 pounds and I understand it will spin a 20B three rotor.
