When attempting to swap motors or doing any repair work, it is best to consult an automobile professional.
no 84 and 85 swap out.
don't think they will interchange one is a straight 6 the other is a v6
The 2.8, 3.1 and 3.4 are all the same block throughout all years. The only thing that really changed was the style of head, the intake, and a roller camshaft. It should be a direct swap for what you are wanting to do however.
it would be a really hard swap to go from the 2.8 to a 3.8. one the 2.8 is a 60 degree motor and the 3.8 is a 90. i am going to swap the 2.8 for a 3.4 because as far as power the 3.8 isn't much more powerful than the 3.4 and the 3.4 is a very straight forward swap almost everything is interchangeable.
Not without a LOT of customization.
Should be a straight swap. Are you looking for specific details?
no.
With some minor modification, yes
No. They are not interchangeable.
absolutely! check out paisteboy on youtube. i did the swap with no problem. he will show you how to swap the 2.5 for a 6.5hp motor.
yes you can they drop in without a problem have done a 5.3 for 4.8 swap and a 5.3 for 6.0 swap only problem we ran into was the hub for the 700r4 trany you can buy from teh dealer if you need it.
yes, but you have to do some fabrications to the motor mounts.
