3V 6.8 vs Chev's 8.1
Has anyone had any longterm experience with the 3V V10 vs Chevy's 8.1 motor (no longer avail). The hp and torque #'s are close. I remember when I test drove the 8.1 it seemed like it had more strong low end feel but really lacked top end. The V10 is so smooth I am wondering if that had anything to do with the 'feel'...I do admit the 6.8 3V V10 had better mid range and top end. This was with 3:73's though on the Ford so that's why I went with the 4:30s eventually. Unfortunately I don't know what the ratio was on the Chevy I test drove. Any comments would fun to hear...

The 8.1 just got totally phased out if I am not mistaken. the 3v V10 has TONS of power and no real issues. The *only* potential issues would be plugs, which can be remedied with regular and early maintenance.![beers](https://www.f150online.com/forums/images/smilies/beers.gif)

I know that most late model GM truck engines have a piston slap issue. My wifes 2003 tahoe with the 5.3 has it. However, the 8.1 tranny also got you the Allison Transmission. Personally, I know of only one person who has the 8.1 and he's had good luck with it.
Unlike our Ford's, GM does not badge there 6.0 and 8.1 powered trucks differently so I don't know how popular of an option it really was. Personally, I am not a big IFS fan so I never really considered a GM truck for myself. I will say the wifes Hoe rides nice though
.
Anyway, I drive a V-10 with no regrets and I've had plenty of different trucks including diesels. Enjoy your truck.
