can i use a van 3.1?

what is wrong with the 2.8 you should be able to run a 3.1 crank in your 2.8 I would rebulid the 2.8 with a 3.1 crank mill .040 off the heads and a good camshaft if you are not looking for performance you could just rebulid the 2.8

It has the wrong engine mounts so it wont work. The van engine is a FWD motor.

The only easy bolt in motor is a Camaro donor or a Crate motor. A 3.1L could use 2.8L injectors with a bump in pressure but it also depends on your final power output too.

I'm replacing the old 2.8 in my 88 4x4 blazer... i'm wondering if the 3.1 used in early 90's chevy/pontiac vans work as a doner engine. I know they HAVE a distributor type ignition, but they are front wheel drive. So basically will that engine bolt to my 60 degree RWD 700r4 trans? And i have read that you should use larger (4.3) injectors for the 2.8-3.4 swap, but since im using a 3.1, will my 2.8 injectors work? Or if i use the 4.3 injectors, will it be too rich? I have also read that i can just bump up the fuel pressure to accomodate the 3.1 with 2.8 injectors? Thanks for any help! Brian
