Great Job By You !

Thanks! It's a lot of work but will be worth it in the end. We're thinking 650-700 HP, on pump gas, with a streetable solid roller cam.

Where are You located at ?
In The Midwest ?
I am not too far from Chicago . Downstate.
Most Chevy only shops would not have touched that 510 Aluminium Pontiac Block with a 20-foot pole.
I have a favorite machinist and he is a long time old friend.
Runs a Small Gas & Engine Diesel Machine shop.
I have several Factory Pontiac 455's.
Getting ready to build one for 2016.

I have heard that IA 1 Blocks had quality control issues.
IA2 much better but still must check carefully .

I don't need IA2 right now.
Be nice someday.
I like Cast Iron.
Aluminium just too Exotic and expensive for me.

I am in the mountain country, Tucson, Arizona. A little ways from the corn belt.

Except for the weight, cast iron is much better for an engine block than aluminum.

all together compared to the all iron engine, how much weight is saved with this engine? For some reason I feel like the crank size and those sleeves keep it from being a lot.

Thank you for taking the effort to share your work, it's really satisfying to see!

A factory iron block is somewhere around 175 lbs. An iron All Pontiac IA2 block is somewhere around 240 lbs. I would say. This block with sleeves, I'm guessing is around 125 lbs.[much easier to move around and flip over than an iron block]. The crank is maybe a couple lbs heavier than a 455 crank. The rods are lighter than stock rods, and so are the pistons. With the aluminum heads, and intake, I'm guessing this thing weighs around 500-525 lbs. A stock factory 455 is around 610 lbs.

So to answer your question, I'm guessing you'd save somewhere around 75-100 lbs.
