Default Originality - why stroke your 427?

There’s a current thread here on Club Cobra about the sale of CSX4158

Alloy CSX4158 Fpor Sale

On the sale site…

https://www.hemmings.com/classifieds...x/2112904.html

…part of the description reads:
“Countless hours spent insuring that this car duplicates the original in all respects”


Then I read in the engine description that the engine is a “Shelby American 427FE V8 aluminum block stroked to 468 cid”
Checking my registry, CSX4158 was built in 2000 and has been sold a number of times, as well as having been rebuilt due to flood damage, so if I make a couple of comments about originality, I’m assuming that I won’t be offending the original owner.

My comments/questions:
OK, so the decision to go with a new aluminium block is taken (when original cast iron 427 FE SO’s would have been reasonably easily available), but why stroke it and lose originality? Is there not enough power developed by a 427 FE SO (or a 428 FE)? I’m looking at an Autocar road test from 1967 of a 427 Cobra, and the comment is “The back tyres spun nearly all the way to 60-odd mph in 1st” and “we paced out the black marks later and found that they went on for a conservative 60 yards”.
Is this not enough power for you ‘strokers’ . Maybe you have stocks/shares in Goodyear?
Back in 1967, the 427 Cobra was compared very favorably in acceleration terms to a Ferrari 365GTB/4 (Daytona), so my question is why stroke the 427 for even more power? You’re losing out on originality, and also losing out on driveability….yes/no?

Looking forward to the “2 cents worth”

Cheers,
Glen
