Most projects like that are tied to "what is the cost going to be" ??  There was no four-cylinder version of a 426 , which would have been 240+ cubes. There was a 301 and it would have had PLENTY of HP/torque to tear up anything behind it in terms of a Fiat driveline. I'd guess wheel base may have changed 6 to 8 inches and wouldn't have been much of a hindrance to nimbleness.  The biggest flaw in any 301 was the fact they never went to a 3-Oring cylinder sleeve like the 426. Coolant maintenance is critical to see to it the engine doesn't die an early death from sleeve pits or Oring failure.

200 cube 433-I four-banger was only rated by A-C at 100 flywheel HP max. The 301's were as high as 145 flywheel HP. You and others can argue all you want over what a PTO dyno says (and most of them read high), but there's no 433-I engine that will make more HP than a 301 with a turbo.  Cooling problem?? .. never had an issue with that on any 6080 I serviced if the radiator was clean and the rest of the cooling system was up to spec.
