Ok I have a 1997 Grand Marquis LS and I was wondering what would be the best mods to do to it. I'm really aiming somewhere for 350 400hp naturally aspirated. Any advice?

Buy an S/C'd Maruader.

Have really deep wallet my friend! I put a 4 valve in my car and did a lot to it and it was only 310 hp. I think you would have to build a motor and buy a lot of parts to do this. I would SC it before I tried that as it would save you money in the long run. This is just my opinion. :)

You'd be lucky to get 300HP NA. 350 - 400HP no way!

What they said... S/C it.

I have to agree with the others...350-400 HP out of an N/A SOHC? It'd be less expensive to just buy a Marauder outright.

Do a PI head/upper intake swap, then buy a tork tek supercharger. N/A with a NPI motor, pushing 400rwhp is just to stupid and costly.

Take a gander over someplace like Sean Hyland Motorsports. Not a pitch for him or anyone else, but you'll get the basic idea of the cost you're up against. Figure around $14 for a complete crate engine for what you're looking at. If you can do the work yourself, you can probably half the price.

Paul you did mean $14k... right.... ;)

Ooops, forgot the K. As for the build, if you really want to, just do it. I won't call anyone stupid for daring to be different. If money was no issue I'd do it.
