GTV2000 engine swap?

[JohnHuntD@domain.elided]

Hi all,

1) Does anybody know how much a '73-74 GTV2000 f.i. engine weighs with all 
engine-mounted accessories but not including fluids?

2) At the risk of outraging all self-respecting Alfisti, has anybody 
successfully swapped into a GTV2000 without butchering it a 
larger-displacement (i.e. 3.0 - 4.0 liters) all-aluminum engine from either 
some other Alfa or another manufacturer? 

I love the looks and handling of my '73 GTV2000, but it is sorely lacking in 
the 'go-power' department. A respected local Alfa mechanic did a compression 
test and test-drove it, and concluded it is a "good-running Alfa" as opposed 
to having a sick engine. 

I'm told with the usual hop-up modifications the power can be boosted to 
about 160 HP, but that power is only achieved at 6,000-7,000 RPM. I'm more 
interested in increasing power in my daily-driving engine speeds of off-idle 
to 3-5,000 RPM. 

I'm not keen on turbocharging, and I've not heard of a supercharging kit for 
a GTV2000. I've done engine swaps off and on for 40 years in American and 
British iron, and I'm wondering what the alternatives are for installing in 
my GTV a lightweight engine with substantially  more displacement that is 
light enough to not upset the Alfa's weight balance and make it a nose-heavy 
beast. Somebody out there has bound to have done it and lived to tell about 
it.

Thanks in advance.
