Oh yeah.. Something to think about.. What you pay for some H/C packages you can get a forged 346ci shortblock.. That coupled with dual springs and a nice cam would get you 400rwhp NA and allow you to spray a 300 shot easy if it is setup correctly. With a A4 and a 300 shot you have a 9 sec car. That's if you have the correct suspension and Tq converter. That way you get to keep your other longblock for warranty purposes.
