i have replaced the o2 sensor and the map sensor along with all the vacum line and my 89 didge d100 v6 5spd. still doesnt have any power past half throttle, and will not pull 4500 rpm in neutral, so i am going to put my 300 hp 318 in it. What will be the hardest part of this swap. Motor mounts have to be relocated? new radiator?

thanks for the help

 

it will all be hard, just get a couple friends to help you out, you should probably be able to do it in a day or 2.

 

the motor bolt right up to the transmission right? And all the wiring is almost identical right? my man problem will be motor mounts?

thanks

 

try getting rid of your cat convertor man....it sounds like that might be your beef.

 

I agree! Have you had the cat checked? Remove the 02 sensor and see if it runs any better.
