Having been involved with NASCAR teams and their engine builders for quite a few years, here are my thoughts that you might consider before buying a used NASCAR engine to put in your Cobra.

About the only standard manufactured part in these engines are the Block, which comes from Ford. While the Heads are Ford racing heads, when the team is done with their modifications, it is now a custom part.

Every Nascar team, and each of their engines they build (50+ per year for many Winston Cup teams) are individual and different. They build their engines, machine their own heads, valves, connecting rods, rocker arms, cams, cranks, etc. They make different engines and different internal parts depending on the track to be run on, and then they continually modify parts, experiment, etc. throughout the season. So what parts are actually in a given engine you might buy will be a mystery to you mystery without tearing it down, and they are all custom at that point. THUS, you won't be able to buy replacement parts for almost any of the internal engine parts. You are much better off for the money to buy a Ford Crate Motor, or build one yourself. That way you have off the shelf parts you know and can buy replacement parts anywhere.

My 2 cents.
