I've got a 88 S10 Blazer with a 4.3 was wandering what all is involved in changing it to a 2.8 for my mom.The 4.3 is locked up,and I have got a good rebuilt 2.8 & rebuilt 700r4 tranny out of my other 88 that I took out to put a V8 in.

 

Lets see here. A different exhaust. swapping over PCM. Anyother engine control management. motor mounts, tranny mounts, drive shaft, may not be able to use 4x4, swap radiator, Still got the induction parts? (air cleaner.) I think there are some other parts I'm not listin here....

 

I've still got the computer the exhaust radiator and everything for the 2.8.I was mainly wandering if there was a big difference in the computer or not.

 

They are both TBI engines.

 

The PCM? See if the harness will fit into the power control module.


I think a 6 cylinder computer will look for 6 cylinders and the lack there of resulting in not running. Only my opinion.

 

The 2.8 is a 6 cylinder too.

 

oh, duh, I forgot.

Also is the bolt pattern the same on the Tranny bell housing and block?

 

I've got a rebuilt 700R4 for the 2.8 allready.Bought it and put it in when I was still using the 2.8 in my blazer.

 

i was just wondering how hard it was to swap from the 2.8 to the v8 im lloking to put a 350 in mine

 

I bought the kit with the motor mounts headers radiator and everything,so it wasn't that bad.
