Jeep yj V8 swap axle question

Hey everyone, I am planning on swapping in a Chevy 350 V8 or amc V8 into my yj. I have a 94 yj with 5 speed manual transmission. I do light to moderate wheeling and was wondering if my stock axles the Dana 30 and Dana 35 are fine for the upgrade. I have gotten mixed reviews on the web. Thanks!

You will get mixed reviews here also, how big of tires are you running?

I mean sure you could drive on it but a 4 cyl auto snaps stock 35 shafts with a 33's and too much of a bounce.... if you try to put v8 power to the ground offroad ur gonna break and possibly on the road too.
I come in peace.... I mean you no harm
Currently in the stable: ... 97 tj 4.0 5 speed stock....04 tj 4.0 auto 4" and 33's... 98 tj roller for future build... 94 yj sahara 4.5" RE and 33's... 92 yj sbc 3/4 ton axles and 38's... Cj5,7,yj,xj,ex mud dragster project

I broke my 35 with a lunch box on the street with my mild 350 and auto.

People do it all the time. That doesn't mean that it isn't going to fail very soon. I would like the peace of mind that I could drive my Jeep any time I want and know if isn't going to fail any second.

all depends on yer right foot. take it easy, and it will last. take advantage of that new found power, and it will soon let you know what else needs to be upgraded. just be prepared to deal with it, and have fun.

I went through the same thing trying to figure what I needed to do when I was putting a 350 in. I had a lot of others say it would work fine if I kept my foot out of it. My D-35 died with my six still in it. I replaced it with a Ford 8.8 and replaced my D-30 with a high pinion D-30 with 4.10 gears to match the Ford 8.8. Not quite 2 years and everything going good. P.S. I was running 33" with the 6 cylinder when the D-35 went.

Factory Dana 35 was barely adequate for a stock vehicle. The factory D35 will bend a little with everything completely stock while standing still. The D35 was just enough for stock. Nothing else.
