will a Dana 300 last?
 

So I am planning on swapping my 6.9 idi into my 85 toyota 4runner I am trying to find a t-case that will give me a good crawl ratio for it do you guys think a dana 300 will hold up behind a 300ish hp 6.9 idi?

hhhmmmm..... the 300 is pretty tough. What kinda TQ will a 300 HP 6.9 put out?

not really sure but I was thinking of running these gears in the case

LoMAX™ 300

they seem pretty strong but not sure if it would be worth the money or should I save for the Atlas tcase

An Atlas would be awesome. Orr just go old school/cheap school and do the 205/208 doubler :D

the only problem with the 203/205 doubler is the length I am planning on shoving the motor back through the firewall so i am kinda afraid of drive train length

should last my dad has a dana 300 behind a nv4500 tranny behind a 454 big block throwing 500hp in his 88 wrangler/crawler

300's are tough. One of the guys I trail ride with has one behind a 468 with a transbrake. He street and trail rides it and also puts nitrous and paddle tires on it and mud races it. It's in a wrangler and runs pretty decent. I don't see a 6.9 putting a much stress on it unless you've got 500 to 1 gearing in front of it.

That is an AWESOME looking yota. I wish i still had my 85... :cry:

thanks guys for the input yea I sold this 4runnerr once and weent back 3 days later and bought it back wont make that mistake again.

Why would you put that huge friggin motor into such a truck?
