I'm not anti 4.3, I just see alot of better options rather than the 4.3L
Staying Toyota engine / tranny is just a better option for easier buildup purposes and availabilty of aftermarket support.
I will agree with you that having less adapters is certainly a bonus, but I disagree that other Toyota engines have as large of an aftermarket than the 4.3 does, especially dollar for dollar. Again, I respect your opinions and hopefully you can do the same.
