Again, thanks for the info guys:
I figured the 2.8 would be the way to go. The only thing that makes me hesitate is that I have a spare 2.4 in the garage (along with a 4 bolt 350) and various transmissions etc, so I would add another 2.4 to the pile if I sourced a 2.8 to swap in. (my wife is gonna have a kaniption)
OH well, HP is worth the from the wife.
Excuse my ignorance, but if I were to hunt down a 2.8 in the JY, any particular years better than another....keeping in mind that I will be keeping my dual weber setup.
