305 or 350?

I am bouncing back and forth between a 305 or a 350.. I'm leaning towards a 350 but I'm not really sure if that will be over kill or not. It would be going in a 91 YJ. I will be upgrading to the ford 8.8 before the swap so no worries about breaking the axle. On top of that, how does the 700R trans hold up off road, or is there a better transmission I should be looking at?

Also, if I go with a V8 swap do I have to worry about my front axle?

I'm no expert on v8 swaps but I can say that the stock front axle will not hold up well to a V8, especially if it sees any off-road punishment and you put on oversized tires. Look into a 1 ton up front. Maybe with Molly shafts it will last as a street queen. Even then I would be weary. Hope this helps!

depends on how you plan to set it up and use it..305 will give comparable power to a 4.0 and the front axle will be fine if you don't go too big with the tires..I have had several cj7's over the years with hopped up 350's and love the almost hotrod performance.I have run these engines with stock axles,1/2 ton axles and 1 ton axles.They have all held up but I prefer the 1 tons,especially with bigger tires or if I plan to punish it.700 is a good transmission but I tend to go with 350 turbos mostly because they are shorter and more heavy duty.No doubt that 400 turbo is stronger than either of these

I won't be going any larger than 33's so will the 30 be ok?
