350 swap
 

I have heard that 350s are a bolt in swap??? Does any body have any good info on the swap ?? I am trying to decide what swap to do this summer

it will bolt in but only if you use a 350 from a 1/2 ton 78-82 short wheelbase 3 spd auto chevy van. if you get one from the long wheelbase you need a trans adapter.

I have the ax5 tranny in pretty sure is that still bolt up and what kind of trans adapt woul I need.

Honestly i would lose the ax5 its not super strong and the torque from a v8 might kill it.I would do a small block turbo 400 or a beefed up 700r4 or a stick a nv4500.Then you have t case options the np205 and dana 300 are the best to run.A step down would be a np208 or np241 both are alum case chain driven.But with a strong drive train the axles would be the weak link.

350, 400 or a 700R4 and S-10 231 with the Jeep SYE kit. Get it in place and build everything. It's what I did.

I wish your pictures in your build thread werent all dead... :(

I fixed most of the first page, but it's turning into a major undertaking. Maybe this weekend I'll fix it all. Maybe I'll work on the Jeep too. Any questions, just ask. It's not a simple job, that's for sure.

Or a rubicon 241!

Easiest is a 350 with adapter to chevy bellhousing... clutch is a bolt in chevy clutch then 231 just bolts up the same as well... only engine mounts and one adapter to do... rest is autozone parts

The rubicon 241 won't work on any gm trans its a 23 spline and gm used 27 or 32 depending the trans.

Well its not a bolt in no... I'd imagine you could swap a couple parts on the case easily with a GM case... and retain the 4:1 and sye... the GM 241 is a bolt up though and drivers drop if need be...

A rebuilt rubicon np241 is 1900 bucks the adapter kits i found to use a 700r4/4l60e is 500 to 600 bucks.Or a lomax 3 to1 np205 is 1600 bucks and adapting it to the 700r4/4l60e is around 300 bucks.Or another option dana 300 used 300 to 500 bucks lomax 4 to 1 gear set 575 and 700r4/4l60e adapter around 500 bucks.

why would you buy a rebuilt rubi 241? buy a chevy 241 $100 and rubi 241 $800 to $1000 and some RTV... and where you get a 300-500 price on a dana 300? they are on pirate or anywhere else twin sticked and flipped ready to go for 300... i can get from the junkyard for 50 to 100 stock...

Buying a used t case you never know what your really getting tell you open it up,If you buy one rebuilt its new and ready to go today.The dana 300 prices was what i seen rebuilt ready to go,yeah a junkyard one will be cheaper if you can find one.

Transmissions I'm worried about when bought from a JY... engines as well... cases are rarely bad... specially when it comes from a rubicon which is not gonna be that old... I'll never buy new because of fear of buying bad...
