High Performance 318ci

You're missin the point. But ok, carry on.
You guys are totally spoiled by easy access to all the parts and cheapness off all this stuff. Please understand that every single part costs me 2x the price on summit after I get it shipped and taxed. Also 300$ block for you is 1000$ block to me due to weight and size.
Another thing is that owner of the car is simply looking for some extra power. He initially planned to leave the 318 stock, so probably like 200hp. After he saw the change in 240hp 72 daemon I mentioned earlier he started thinking that it could be good to get some more power. He has plenty of fast cars, that includes 68 charger with 511 hemi and also 1200hp hemi coronet for 1/4 mile racing. He has enough race cars but if his wagon can run better with some mods, why not do them? He wants to keep it 318, keep reasonable gas mileage and make it good long distance cruiser with some extra kick.
