But there's one thing that you mentioned in your post that makes a big difference....the word "track".

A track car or drag car needs different things than a street car. Running to pick up a pizza at 1600 rpm, then sitting in traffic in 98° weather, doesn't require an engine that pulls to 7500, nor is an engine designed for 7500 "right" for that kind of driving. You need more emphasis on low rpm engine characteristics and torque.

Truer words could not be spoken. This is a big deal.

But there's something about spending thousands of dollars on an engine, then having to spend another $3-5k on a supercharger. In the Coyote's case, you have to spend thousands on the engine, thousands on the supercharger, and then thousands on the computer and wiring harnesses.

Sadly, you're right Brent. they are not cheap especially when you finish up with the various reliability / longevity modifications. You still have a few performance mods and while parts for these engines are quite good they are not inexpensive.

This one might be a bit of a stretch with a big block if you want to make it a street friendly car like we were talking about, although this is where the blown modmotors excel. In the real world of Cobra roadsters 900 RWHP in a street car might be a little over the top, except for bragging rights.. Interestingly the blown mod motors can actually do that and idle at 650 - 750 rpm with near max torque just off idle. They making driving around town and in traffic or on the highway at 1300 rpm in fifth gear a reality - without bucking and farting.

In the end, as it has always been, it is ultimately the builders preferance that wins out - or at least ought to. From an authentic period correct point of view I just love the FE. From a handling and all around bang for the buck standpoint the small block is very hard to beat. From a pure love of the motor and the visual WOW when you open the hood there are few things like a SOHC. I just love Full Throttle Al's engine compartment. At the end of the line if you are willing to spend the money and take the time you can have it all except the period correct-ness and cost with the blown modmotor. The caveat(s) - you have to be willing to do the work, surrender the period correctness and last but not least, pay the price - literally.

Shucks it's a country mile closer than an LS6 or 7
