Vote 428 or aluminum 427FE??

[RodKnock]

From poking around it seems that the 185 lbs for a 428 is about right. The original cast iron 427 blocks are around 200 lbs. per the Genesis site. The Pond aluminum block is about 120 lbs and the Shelby aluminum block is 125 lbs. The Genesis cast iron block weighs 230 lbs.

Good luck with the search and build.

Wow, that is a significant weight difference for the Genesis Cast block. I understand reinforcement, but that is a good bit of extra meat.
I spoke with a reputable builder and according to him there have been a lot of issues with the genesis blocks. On top of issues with the castings, there apparently is a supply problem as well. That's unfortunate because the price is appealing. Im just repeating what i heard and it could just be that they have a preference for one manufacturer over the other.
