It's a double-edged sword and a slippery slope, but like most, I do enjoy the "build" portion of ownership. You always learn things the first time around that you would employ in your next build.

I think Resto is asking the right questions and should have himself a fine Cobra when done.

We need to get you to branch out in to the "repair" portion of ownership.

Like most, if not all, I'm time challenged. Also, the car has been mostly problem-free (knock on wood). I had an electrical issue sorted out a few months back by a professional, since wiring and me do not get along together.

Was that why you dumped your MSD Distributor?

That was my other problem. However, I don't want to muddy this thread and raise/get the ire of Jamo or Ron.

The numbers I was quoting were from listings I have of Ford crate engines (which is essentially what Shelby was buying) available during the 60's.

There is truth to what Ernie says about the the numbers being "conservative" all engine mfg's will quote a "minimum base line HP rating", in some cases it was real conservative like GM's rating on the L88 427 (rated 430HP @ 5800RPM but failed to mention that it red lined at 6500RPM and would produce in excess of 525HP).

The 426 Hemi, and Boss 429 were very conservatively rated at 425HP.

However at that time high compression (and good gas) was needed to produce these numbers. Still remember laughing at the sticker in my old Pontiac that read: "Your new GM vehicle only requires fuel with a minimum 91 octane rating, so it will run fine on regular gas."

The engine builders today easily produce 600+HP with 10.5:1 compression as long as they don't use any vintage components

So let's run this to ground. Shelby bought 427's off of the Galaxie line for his CSX cars. Those would have been the 410HP 4V or 425HP 8V variety. I would like to hear how he got those engines to 480HP. Have any of the MR heads on CSX 427s that have been pulled later in life shown signs of being heavily worked? Did he re-cam them? Compression bump? What else?
