put together a new shortblock over the winter, dart block, more compression, more cam, more carb, still naturally aspirated. tested last weekend and ran an event yesterday. Still working out getting all the power to the ground with suspension and shock adjustment, the new radials are a little bit of a challenge. Managed a new personal best of 5.95 @ 115 mph, 1.30 sixty foot in the 1/8th mile. can't wait to get on a "good" prep track.
