Regear! 3.73 or 4.11?

Depending upon tire size I'd say 411 and never look back.

Oh I'm definitely building it to be a driver. That's why I went with the EFI and stuck with the milder cam for now. It's got plenty of torque down low which is fun around town. And with the EFI, you just turn the key and go.

As for tire size like some of you mentioned, I have 235/60R15 all around. That comes out to 26.1".

And I forgot to mention, I'll probably throw in a Powertrax locker just 'cause. I've run them for years and I like them. Plus burnouts are better with two black streaks on the pavement.

Thanks Airdrie AMX. That's a pretty close comparison. I just gotta convince the wife I need to rebuild the axle while I'm doing the 200-4R otherwise I'm gonna only be using 3 out of 4 gears for a while. Maybe I can get some stuff sold off on Craigslist and avoid running this through my "accountant" altogether.

3.73. A 3.54 would be workable, but with a looser stall and bigger cam you might find yourself shifting down more often than you'd like. My 2003 Tundra w/4.7L V-8 and 3.91 gears will drop out of OD on big hills with a bit of a load, or to maintain speed sometimes even with no load, but only on long or steep hills near the lake at my house. On the Interstate it downshifts only when I have a load or I'm in the mountains.

The suggestion of a 3.90 gear does sound like a good compromise. OD ratio is 0.84 instead of the more common 0.80, so it's a bit steeper. With a looser convertor you won't need more gear, so I'd go either with the 3.73 or 3.90, and my personal preference would e the 3.73 for a driver. Hey, the Toyota rear axle is beefy enough but is too wide for a Javelin... it's 66.75" WMS to WMS, Javelin is around 57" for the early models, I think the 71-74 is an inch or so wider? If you want to change axles an Explorer would be a good fit...
