Did it years ago with a buddy's Duster. We used long rods and custom pistons to build some compression. It had Edelbrock RPM heads ported by Dwayne and a small Ultradyne solid roller (236/236). That sucker ran hard! Made 600 hp and pushed his mostly stock Duster into the 10's on street tires with full exhaust, full interior, etc. No rollbar, nothing. Just went to the track, ran some 10's and got kicked out. He drove that car to work for a few years and then got married and sold it.
