Hey guys, i am looking to buy a 2011 mustang GT that the owner has stated has a Boss 302 and transmission swap. Is there a way to tell if it is a genuine Boss 302 motor besides the intake manifold and valve covers? Obviously a lot of people add those as aftermarket parts. Do engine blocks still have vin or serial numbers these days? Will the forged crank be different? Different compression than a gen1 coyote? Can a ford dealership mechanic confirm? Thanks in advance!
I think you can come close to the redline of the Boss engine (code name Roadrunner? am I remembering that right) with a regular Coyote and a tune; but I remember reading they had to speed up the ECU in the Boss, in order to "keep up" with the higher redline . . . also I would think that the tachometer would need to be changed, to reflect the new redline, on a true/complete Boss conversion

Yea that makes sense. I think the boss has a track key too that changes the ECU. I think it also has a different oil pan than the GT. Bigger. And an oil cooler. Maybe i will look for those?
an engine swap might not have included the "ancilaries" such as the oil cooler (or oil heater, as it is affectionately known at the road track, LOL) but it should have included the larger oil pan

That might be an easy check. Just pull the part number off the bottom of the oil pan. Im out of ideas! Lmao.
Only thing I can add is if it was out of a Boss it should have a ID tag on it like this…. If it was a crate engine swap who knows…
My only issue is, a lot of people have those intake manifolds on their GT or F-150. When people supercharge their Boss, they sell their manifolds. I see them for sale quite often. Thx for the input/ help though.
The boss has different heads and exhaust cams. If you can find the part #s on the heads a cooperative parts man may be able to verify whether they are Boss heads or not. The oil pan is the same capacity as the GT, but has different baffles. The valves are slightly bigger and the springs are stiffer. The connecting rods are still powered metal [ AKA, pressed sh*% ] but stronger, same as Gen 2 rods.
