Took almost 2 years, but the 3FJ40 is driving (3F-E into my 40)! Yay! Immediate notes: 3F-E is WAY faster. RPMs feel like a re-geared 2F. It has power throughout much of the band whereas before it did not with the aged 2F. Considering the auto tranny in the 62/80 is about 20% higher geared than my H42, it's almost like driving it with 4.88s with those stock tires and 4.11s. Yeah, I know that the RPMs are fine, but it's amazing how much more grunt this seems to have (okay, granted my old 2F was getting pretty worn). The annyoning stuff now like the new 4core radiator I got busted a seam on the inagural drive home; the muffler shop exited the pipe out the BACK of the cruiser when I clearly said the SIDE and causes some seriously stinky driving, the new 4" lift springs lift the front WAY more than the back . Thigs to do: 1. New fenders 2. Take top off 3. 315 tire swap from the 80 & 16" wheels from a Tundra (got spacers). 4. Roll cage. Man that radiator makes me MAD!
