I have seen bigger diffrents in big block Chevys.

 

When you have 400+ displacement it doesn't care that much.

 

Question 1: it's still a full removal rebuild and reinstall to change just the block to an HO?
Question 2: do you still get the increase in power from 177 - 192 doing it that way.

 

If I decide to go with option B, would I be able to still run the original tranny from my 90? The thing is that the donor vehicle is a 97 2WD Cherokee Sport, so I was thinking of using what ever I need for the swapt and part out the rest. Would it even be worth the trouble?

 

Yes, No.

 

Of course, the tranny is a bolt on. The difficult part of a swap like this is the wires. You will need the entire engine harness, bulkhead connector and fuse box included, to do a clean job. We can help you out if you decide to do this. There is nothing you can't do when you have a wiring diagram, some help and a lot of patience.

 

Thanks I appreciated. If I go that route I will be parting out the rest of the 97, the problem is where to do it.

 

Are all of the Cherokee 6bangers HO after 91, or does it have to say it on the body ?

 

Yes.
