OK. After reading through a couple of post, it says that I need a custom motor mount in order to do this. Would it be easier to swap in a S/C 3800? BTW, I'm sorry about all the questions.

There has been a few 3800 swaps. I've heard that needs more than one custom mount.

So the 3800 is out of the question. Now back to the 3400. Is there a swap guide that goes into depth. Also, would I have to convert to OBDII or could I just keep what I have. How many people have swapped 3400s in pre 92 cars on this forum?

Look on V6Z24.COM under 3400/3500 swap mount.
There is a guy called daveydude who makes them.
3500 is alittle harder but still way less work than a 3800.

Thank you.
edit: I found a PDF Blueprint on V6Z24.COM along with some other useful info.
I also tried 60DegreeV6.com and I found a 2.8 to 3400 swap thread but when I click the links it just takes me to the home page. Maybe I should just search harder

While reading through the blueprint, it says that the mount is for a manual transmission. I was going to use an automatic so that could be a problem. What modifications can be done to the mount so I can have an auto?
