awesome car, glad you have your dream car

This is the one off my motor, taken this morning. 499 pounds.

Uoah...500 pounds is not what I expected to be honest. What weighting there so much? Heads are aluminium only block is iron and crank are quite tiny also...

The heads are pretty big, as is the manifold and water manifold. The block is deep skirted with 6 bolt caps. When you think about it, you can see where the weight is. I was shocked liked anyone else though!

I was shocked too that was when I saw the prints and CAD data for the R07 block and heads. Having worked for GM Racing you get to see things like that. But the block alone is like 225-250 or so. Almost mega block wt. That is where the wt is at.

One thing I worked on when I was at GM was wt reduction of the heads. Trying to find a few ounces here and few there. Without compromising the heads. The blocks the teams lightened if they wanted. But that much wt that low, is better then wt higher up. I think I saw mentioned the cars are titanium so add an extra 4 pounds to the numbers you saw.

Yes the heads are almost as big as my Indy heads for my BB. Crazy stuff.

The water cross over is only like 2-3 lbs, not much but it adds up.

If I can be of any more help let me know.
