New Duster
Thank you everyone!!! I just found out that even the glass is original. I am really tempted to put a small block but then again original would be awesome. What do y'all think?
My opinion of swapping in a V8 to a car like this is well documented on this board, but at the risk of boring everyone to death ONE MORE TIME, please consider the following:
Swapping in a V8 (273-360) is probably the easiest way to get decent street performance out of a car like this IF you are a novice mechanic and don't have a lot of mechanical experience.
If that is not the case, you can either
1. leave the slant six in the car and work with it, normally-aspirated, by milling the block or head, installing a better cam, headers, a free-flowing exhaust system, re-curving the distributor, and adding a two-barrel carb on a Super Six manifold, which will probably net you a car that will; run fifteens at 85 mph, OR
2. go the other route (recommended IF you have a lot of experience) which is adding a turbo or supercharger and ending up with a car that is considerably quicker/faster, but requires a lot of knowhow to get the most out of.
Most folks don't have the patience or experience to effectively hop up a slant six, or successfully add forced induction to their ride, so a V8 swap is the best or them.
If, on the other hand, you like a challenge and have the patience and experience to deal with the many problems a turbo engine is likely to give you, the rewards can be awesome.
Building a normally-aspirated slant six with the aforementioned mods is not likely to give you the most bang for your buck, because the head is a bottleneck in the breathing system that cannnot be successfully circumvented without some help (turbo or supercharger.... or, nitroua.) My opinion, only...
You spends your money and you takes your choice.... :)
