I did not know the engines were different, I assumed they they had the same chassis in the rental units that they sold to you and me. Do you think the 5.4 V8 is more reliable than the V-10?
If I'm not mistaken the 6.8 V10 is literally a 5.4 with a longer crank and block to accommodate two more cylinders. If you do the math the cylinder sizes are exactly the same. I suppose the 5.4 might be incrementally more reliable with fewer moving parts, but both are very reliable engines.
Yes, they're both examples of the Ford modular engine family, sharing the same cylinder spacing, bank angle, and other key block dimensions. There are some other differences between the V8 and V10, though, such as the addition of a balance shaft to the V10 (as required to keep vibration under control). Both are quite reliable engines.
I sometimes wish Ford had made an 8.1L V12 engine as part of the line; that should make for a very smooth running and decently powerful engine.
