Hmmm. Interesting idea to tuck the bumper in! I'll have to take a look at that for sure. It kinda sticks out a lot. Should be no big deal to shorten those filler panels. Also shaved a few pounds by replacing the heavy bench seat with lightweight buckets from a late model Cougar. The last thing I have thought about is an aluminum driveshaft, Which should also help acceleration. Let's keep this thread going and see what other ideas come up!
