Tomohawk engine weights

hi there guys. I recently saw a Tomo engine that was 480 pounds complete! Wow! So that brings up the question:

Where was the weight savings? I’m guessing the alum block can’t be too much lighter than a 455 block filled with hardblock full and a girdle?

 

It weighs more than a stock block and less than a girdled

 

Interesting. The alum heads and intake what about a 60 pound savings vs stock?

 

There about yea

 

but they are capable of over 2000 HP

 

If you can get parts to put them together

 

Complete Stock iron Buick BB is 596 on that same scale..

Savings

Exhaust manifolds- 40 lbs?
Heads- 60 lbs
Intake- 30 lbs

That's the majority of it right there..

Thanks JW, have you ever had a chance to weigh a 350? There is some controversy about the weight. Some claim 450 pounds all ready to go.
