Anyone here have an HPE Iron 408?
What are your opinions on this setup?

How much more does this block weigh over an aluminum?
What heads/cam combo did you go with and what are your power numbers?
Thanks

I have one of their short blocks. I went with a cam they recommended. I think it is a custom grind 244/248 maybe. I will be returning when they get some AFR 225 62cc heads in stock. Till then I won't have any numbers.

I have an iron 408 but it was built by a friend of mine. He went with a really small cam for it because its my daily driver and I didnt have the right heads on it either. All of my numbers are in my sig. I just replaced my heads with Patriot Stage 3 LS6 style heads and will dynoing tomorrow and can give you the results if you would like.

Ok my numbers are 454 rwhp and 465 rwtq. I dynoed 43x last time I dynoed at that particular place so it looks like I picked up around 20 hp or so. Looks like I also need a bigger cam, LSX intake and TB and 1 7/8 headers to get more out of my motor. On a side note though I also hit it with a 100 shot and it made 554 rwhp and 709 rwtq!!! These heads must love nitrous or something.
