novacain – here’s my guess; stock fh with just cam (e.g. similar to isky 400) on 90 octane at a track 5700 feet elevation, high 13s to low 14s. If your track is elevation like Speedworld (now closed) in Arizona, about 7/10s faster. If you decide to go that route, you might help that little cubic inch fh last longer by switching to a 3.60-3.90 rear gear depending on your tire diameter : ) It would take a little more effort to add electronic ignition and raise compression and you could subtract another 7/10s, and add a few more cubic inches and subtract another 7/10s, and run fuel instead of gas and subtract another 7/10s and so on and so on… I like your idea to keep it running.
