ok i am yoda die hard and looking for a fj 40 but i have found alot with 2f motor that just are not very powerful.
A 2F is exactly powerfull at the point where its needed.........low down, not in high revs.
Keep the 2F and try out before you decide by a piece of paper whats what, main reason for conversions is lower part prices and better availability of chevy stuff in the US.
