I had to change motor's in my 87 2wd pickup 22re 5 speed.
long story short i found a complete running motor for $400.00 it came out of a 83 car. We used the whole intake off the truck and other parts that were different. Everything is the same other than head, cam and bottom end.
Can some one tell me why this motor don't have the power my old one did?
Is the 83 car cam killing the power of my new motor?

Thanks for the help!!

 

Both years use the same camshaft
