IMO I would only swap from an alum block to an iron block if I were going larger cubes, even to a 6.0 would be pushing it for me...maybe a 370 or 402/408.Originally Posted by MrHorsepowerLSx
Thank you for the weight update...I couldn't remember how much it was lol....but for the added strength you get, it is a no brainer
I guess its just me that thinks that way but thats probably why my truck is still slow.
