I didn't dyno the assembled engine. it has a 3.98 stroke (428 stroke) - i would have done a 3.78 stroke (stock 427) but there arent any reasonably priced cranks available in that stroke that I was comfortable with.

I do have the BBM heads, with a hydraulic roller cam setup. it's really nice and ridiculously overkill for the task. Blair Patrick did a great job with this for me. He is a true gentleman, and he even put up with my requests to assemble the engine myself after he did all the hard work!

I didn't mean to offend RodKnock - But IN MY OPINION, everything about these cars is emotion. The power to weight ratio is well beyond the limits of what we can fully use on the street, and beyond what the chassis can really fully handle.

If I want to go to the track, I will do better (faster and safer) in a c5 or c6 or c7 corvette. If I want to go somewhere, any other car can take me there more practically. For me, this car is purely emotion.

So, if anyone else wants an aluminum block because it is lighter, or makes their car more valuable to someone, or because they like the aluminum theme, then I 100% support them and, in fact, will openly celebrate their project. this is all about fun and camaraderie. I appreciate all of you as brothers and friends, even though I don't post here too often. (I am one of those unfortunate married individuals who has a wife that does not appreciate my hobby in any way.)

But the original question of this thread was asking our opinions about aluminum blocks. In the previous 5 engines I have built (windsor ford for mustang, cleveland for pantera, small block chevy for 57 bel air, and big block chevy for c2 corvette), i have always used iron blocks for cost and reliability.
