5.3 swap questions
Ok. I am not finding all the info i need on here. i want to install a 5.3 with all accessories and stand alone harness into 1985 TA 305TPI. Where do i get motor mounts, and do i need to change the fuel pump? also my 700r4 seems fine would it bolt up at least for now to save costs. Any help?

Check out 3rd Sticky down, up at top of posts.
"LS1 into 3rd Gen...."
Excellent source for many swap questions, and a great start for folks.
In addition, stand alone harnesses have just been discussed, extensively, in another thread.
Good luck with your swap.
