Exclamation Low Power Issue...

Hello....Need some help....

I bought this 75S with full 1977 930 Transplant..

It runs well, feels okay when going full boost...

But i decided to have a dyno run last weekend..

Just before that valve adjustment was done and i noticed the rotor at the distributor is the one with the cut off option...(speed limit)...


As the test raned, very low hp resulted just 236 HP (I was expecting at least 260)..

Should i replace the rotor? or should I look for a worst scenario??..

Here it is the dyno run...

Any thoughts?


Look at how low the RPM are cutoff..today we changed timing, and a improvement was noticeable, 5,500 rpm now.....
