ive been thinking bout a engine swap/ build

mark viii are cheap but most have high miles i was thinking rebuild with forged rods new pistons and slapping a supercharger on it for everything thinking 2 grand or less

or

getting a low mile 5.4 and swapping it in with a hps intake and nitrous for about 2 grand or less

4.6 4v > 5.4 2v, get the mark 8

Why make a second thread for this same question. Stick with the mark 8 as has been said since the last thread.

Is there a thread about the mark8? How hard is this swap?

I am in the same dilemma. PI swap 4.6, PI 5.4, or Mark VIII swap. The Mark VIII swap isn't too bad, check my sig for the guide.

a 4v swap isnt much more than a factory 2v replacement. Its a direct drop in

Thanks I looked through it, awesome info. Would still need to forge bottom end though, if trying for over 400HP.

I say do a 4 Vavle 5.4 Liter

I'm hoping to do a Navigator swap at some point. Have to fix the rest of the car first though.

superchargers are cheap throwing a kit together wont cost to much
