I agree with everyone the 2F is a great motor. I built myself a 40 with 3RZ and I personelly like it alot. I am running 5.29's and 37in tires and it pulls pretty decent. I have one with a 383 in it as well and it definately has more BALLS than need be I have broken tons of stuff with alot of go pedal. If you are ever in WA you can come take the 3RZ for a drive.
