Tried a whole set of springs if I remember. As I said, ran out of time before I could try everything. The HIF6s might have worked better with a different exhaust setup, etc., but just did not have time to get into that. Hope to go back and renew that testing this spring. As it was we spent over 20 hours of actual run time on the dyno over a 3 week period. A lot of time was spent with different springs, different needles, doing custom needles, different damping oil viscosities, developing better anti vibration mounts as we had a problem of fuel foaming in the float bowl at high rpm, developing spacers, then trying two different types of carbs on the same maniflod.
This was a street project so any manifolds were allowed, but the object was to develop a setup that was as close to stock appearance with as many stock parts as possible. Sticking with SU's because everyone has a set and sidedraft webers have gotten so expensive. We ended up with about 155 HP from the HS6 carbs, which was not bad for a 2 liter street motor with 9.5 CR. Not as much on the top end as I would have liked but most drivers would rather have more low end rather than top end.
