427FE weight comparison

[chrispy]

In looking at Genesis's web site, I see that they quote the aluminum 427 FE block is at 118lbs and the cast at 230lbs (30lbs over the original block).

From this I am to assume that the AL block is 82lbs lighter than stock and 112lbs lighter than the original. What I am unable to find is the weights of the original cast heads versus the AL heads of today. Any one know the specs?

Looks like the Genesis block is a little cheaper than the Shelby AL block, but I was unable to find any weights on the Shelby AL block... Any one find it?

What I am getting at in the long run is a comparison of the 427FE as compared to a small block stoker (say 351W). If I am going to spend this much money on a AL 427 and heads, I am hoping that it would get to the same weight as the 351W with AL heads.

Anyone know the actual weight of the 351W cast block? I am aware that the crank, rods, pistons etc... will make a difference between the two, but am trying to look just at the blocks for a level playing field of comparison.


Thanks,
Chris

Chris,

Thanks for the link. Just when I thought I had the ERA website memorized, something new comes along. Very helpful.

Thanks again,
Chris

My iron med. riser heads with 2.25" intakes weigh 44lbs each assembled.
My Shelby alum. stage II heads with the same valve sizes also assembled, weigh 22lbs each.
Hope this helps.

Chas,

Great!!

So if I do my math right we are looking at 126lbs difference from a original cast iron block and heads versus a AL block and heads.
