Hello everyone,
I hope someone can help me out with a couple of questions/concerns I have. It's concerning a 351C aluminum block. The block was previously decked .025, prior to me having it (originally 9.5 deck height). Does this modification weaken the block, or create a problem(s)? My other question is, what's the maximum horsepower/torque a 351C aluminum block is capable of holding up to? Shelby claims that their 427 aluminum blocks hold up to 1,500hp!! I appreciate any help. Thanks to all in advance.

Welcome to M&M !
.025 removed from the deck will not weaken the block whatsoever.
Former UDRA Pro Stock driver Animal Jim Feurer stroked and poked his 351C aluminum blocks to 427 cubes and used No2 with considerable success "back in the day".
Properly prepared I cannot see any reason that block could not withstand 1000+ HP.

Moneymaker,
Thank you for welcoming me to M&M. Having read your credentials, I know your information is credible. I'm happy to learn that I should be OK to use this block. You mention that properly prepared this block can withstand 1,000HP. Is there a machine shop that you have trust in, that you would recommend to me? I want to build it right, with a stout bottom end. Thank you for your help.

Is this an SK part number Ford aluminum block as shown here:

http://www.bacomatic.org/gallery/dan-al351c

or an aftermarket block like a Fontana?:

http://www.bacomatic.org/gallery/Fontana-Engine-Builc

I know the Fontana is available in 9.2" and 9.5" deck versions but all the
SK aluminum Cleveland blocks I've seen were 9.2". Does the block take a
351C oil pan or Windsor. Ford also made 9.5" deck 351W SK aluminum blocks
and there are various other aluminum blocks that could be had with Cleveland
mains.

If you look closely at the Ford SK aluminum block you'll see it has been
repaired in the lifter valley area. That was apparently a weak spot as I've
seen several that had failures in that area. The Fontana has webbing in
that area and is a stronger block overall.

What heads are you running?
