The gearing is wildly different with the 351. None of the values line up.
Would love a stock engine tune since the odds of getting the swap in roulette are miserable. I've been playing for over a year and no luck.
OK, here is what I did to use the Maestro's tune for a stock engined Pantera, which is a 351 Windsor Ford, same as a bazillion Ford Crown Victoria police cars.
For the transmission: 1st:2.285, 2nd:1.636, 3rd:1.275, 4th:1.060, 5th:0.897, Final:3.130
In the interest of achieving better fuel consumption, I left the engine Normally Aspirated, however, I modified it by: Upping the bore and stroke using high compression pistons and a race crank, added the high lift cam, and a Balance tune with Port Polishing. That produces 522 HP@6300 RPM and 475 ft.lbs of torque@ 4200RPM with 100% ECU and 100% POWER RESTRICTOR.
I changed the Ballast specs to 9kilos at -50 to achieve the same weight distribution of 41% front and 59% rear as per Praiano's tune for the swapped car. My car weighs in at 2460lbs and a PP value around 676PP which allows Race Mediums as is, or even Race Soft with the addition of a little ballast.
The tune above will give me 190 mph on the first straight of LMS. That yummy torque is very similar to my old F-350 7.3 later diesel which pumped out around 500ft.lbs. (It weighed 8000lbs)
As I am sure you know, Le Mans is probably 75% strategy, so if you can resist upping the ECU to FM1, the car will easily do 3 laps and be in the lead when it is time to pit by staying at FM6. If the radar will allow for Intermediates for rain, you can easily finish on them to take the win, as you may not have to pit again. Race Mediums can be used also in the beginning as they only have to last 3 laps before pitting for rains.
OK, that's my list, anything not mentioned is the way the Maestro tuned for the swapped car.
Cheers, Pete
P.S. Maybe this will inspire Laurent to publish a tune for the stock engined car which will be better??
