Before the Enforcer

From what I've been told(by a retired line chief from a Navy Connie squadron) was that the biggest problems the 3350 had stemmed from the PRT(power recovery turbine), which were a set of turbine wheels installed to scavenge that last bits of useful power from the exhaust, and transferred that power back into the engine via a set of short drive shafts and u joints. According to  the chief, when it worked, it was great, but when it decided to fail, it was spectacular. Each turbine wheel had a series of slots with tiny holes on the ends of each slot, and these were theoretical fail  points to have the individual turbine wheel fail the moment it went into an overspeed condition, allowing it to fail before ruining the rest of the engine.

Other that the PRTs, the engines worked just fine.

That's got to have been spectacular, from the outside anyway.

IIRC, the CA-15 was originally designed with an R-2800. NAA had a design or two of radial powered Mustang variations, altho more along the lines of the R-1830 as an advanced single-place trainer. John Crocker(?) had a design for an air racing P-51H using an R-2800. Considering there are a number of vee powered a/c that were converted to radials, it wouldn't be that big of a transition.

I agree a 2600 or a 2800 would be much more realistic and look better, but hey go for it.
