67 Cuda: disappointing dyno numbers, need some advice!

Okay...... just seemed to take a while.

Do you know if it’s an inertia dyno or a load cell dyno?

If it’s a load cell dyno, then the rate of the pull is controlled/programmed.

If the rockers you bought are 1.6’s..... they might make a few more hp.

I don't know which kind of dyno it was but he said he had to set the roll speed or something before he did any pulls and he did a couple of low speed runs and adjusted the dyno a few times before the real pulls. He also said the rwhp numbers were calculated at a 25% loss. (which seems high, I thought it would be 15% since it is a manual 2 wheel drive car?)

The rockers I bought were 1.5 because I thought the heads would have to be worked so the pushrods didn't rub/bind?
