Final re cap before swap
OK, So Im attempting the V6 - V8 swap....not just an oridinary v8, its a 400hp 435tq 383. I just wanna get this right.
So heres my list -
Engine - getting built
Headers - need
Cat back - need
Starter - need
Alternator - need
alternator bracket - getting from boneyard
Carb - need (holley 770sd)
Oil pan - need
Tranny Cross member- need
TH350 (shift kit) tranny - Got it
Rad - need
SFC's - on order
Torque arm - on order
Ok, so if Im thinking right this is all Im gonna need right?
What are your opinions on power steering? With my 6 right now the power steering belt went and Im not having any problems.... opinions?
Everything else is pretty much straight forward....take that old peice of **** out and put all the new stuff in
Let me know if i forgot anything

I just did a swap and you'll need lots of misc. hoses and stuff. I didn't see motor mounts or if you want a working tach you need a v-8 tach . New springs too but some people leave the v-6 ones in. I also needed to buy a few sensors like water temp and oil pressure.
As far as power steering my old v-6 pump looked the same but I went to serp set up so I just used the one that came with the v-8. Just unooked the hose from the old and put them in the new.

im almost done with this swap. im not sure what else in suspension. mine hasnt really dropped at all and it still has v6 springs, and i still have to drive it. but make friends with ACE because i have to get so many nuts and bolts. the swap isnt hard its just a little tedious. yes tedious....

I don't have the old ones to measure or look at but I am pretty sure they were different. Also new rubber ones only cost 11 bucks at napa or you might want to get polyurthane.
