Shelby Engines Unveils New Aluminum 351W Block

[TerrysSPF]

LMH- Do you really think it would be 100 lbs? I was thinking more in the 40-65 lb range.
Does anyone have any weight figures for a cast iron 351 block and the new Shelby alum block? Who else makes a 351 alum block?

Terry, Ford Racing makes an aluminum 351 block. RDI has built several of them. One of their crate engines (aluminum) makes over 600 HP in the 427 CID stroker version

You could be right, I'm not sure of the weight difference.
Maybe someone can come up with some numbers.

RDI claims their aluminum 427 (based on the FRPP block # 2351) weighs 470 lbs - complete engine
They claim this is 60lbs lighter than the 351 iron version, 180 lbs less than an iron FE, and 230 lbs lighter than the 460 iron version

Hope this helps.

So the difference is about the same as 10 gallons of gas. My question would be, can you tell the performance difference in your car with half a tank of fuel vs. a full tank? If so, (which I doubt unless you're seriously underpowered) is it worth that much money?

I wouldn't do anything to put an extra dime in the pocket of CS.
