My 1st gen 13b Dyno slip!

Went to the bay area bbq and dyno day at ATP in freemont on saturday. I had the only first gen represented on the dyno (and I think the only non-turbo car as well).
This is my set up: 1974 4 port 13B with 89 rotors. Big street port. Weber 48 IDA. Racing beat header with dual long primary exhaust.

Adding the usual 15% driveline loss puts it at about 200 hp at the flywheel.

Note the huge dip at the very end of the power curve. That's my crappy spark plug wires causing a high rpm miss (fixed it today) Might have gotten a few more ponies without that miss.
