Need help choosing an engine!!!

What engine does it have in it now. It's a lot less money and hassle to stick with what brung ya to the dance. However if it's a 198 slant let me be the first to tell you to swap it and let me__ be the first one in line to buy your slant! LOL!

If you go big block, running headers is a hassle. And why would you build a big motor and stick wadded up socks in your secondaries, seems running manifolds would be about the same to me!

I built a 440 to replace the slant six in my Duster without consulting anyone ( didn't know about this site ) and then found out to run headers I had to cut the inner body of my car.

They did however make big block k frames and manifolds for your car and you can probably buy them of someone on this site. I understand they can be quite pricey!
