It makes sense why you think that, but if that's what everyone is thinking, they are very ill-informed, and that's actually my fault.

Actually my build started as a means to get more power, but better reliability and efficiency. A TRUE GT. The rarity aspect struck me as well obviously. Finding parts is no harder. Every single part (on the outside of the motor) is a direct replacement of or with the V6 NA, and V8 NA's. There is no difference other than 2 more cylinders. I mean shoot, every single component on my V8 is from my old V6, that's why I'm parting that motor out, I can't sell it since everything is missing from it. Alternator, AC compressor, Water pump, tensioner, power steering pump, coils, spark plug wires, air pump, vacuum lines, vacuum diaphragms, egr, TB elbow, lower oil pan, oil pump, cam sensor, crank sensor, flywheel, clutch, various bolts etc etc...

Sure you have 4 more spark plugs to buy, but it holds the same exact amount of oil. Same type of oil. Same amount of coolant, and type. The slim mechanical fan is different. If I sold one though, it would come with a more reliable electric.

With the NA 6-speed V6, muffler, K&N's and seats only, I got 24 mpg in town, 32 ish on the highway. The V8 is returning 16 city( my right foot has a lot to do with this), but 32 as well on the highway. Emissions were cleaner, but no one care's about that lol.

My intention was street, and the car is my DD. It's no harder to drive slow, in fact it's almost easier. Starting in second gear and skip shifting, it doesn't bog down as much. Much more useable power.

There is no aspect that it's worse in, other than you can get horrible gas mileage easily, as well as kill yourself in the process. Hopefully now everyone understands a little better.

Lastly, if it helps, I have no valve cover leak. Which is weird because I have never even heard of a 320 that didn't have one at some point...
