ok, my engine builder has finished with the second pull on the dyno. Because of low oil pressure we changed the oilpan to a low pro milodon from the stock oilpan. It now dynos at 535 at 5700 and 535tq at 4500. After removing the 1" open spacer the engine responded better in the low rpms.
I sit and wonder if I should stop there or if I should try something to improve upon this or if this is enough to haul *** with my 72 swinger? What do you think?
