I would stay with the cam in it, mill the heads a few CC smaller than the 906s and let it eat. With aluminum heads and tight quench it will be fine on 93 or so octane. If you need more later than send the converter out for a little more stall. With the much better flowing heads you will need to bump up the shift point but you shouldn't lose much if any down low. 50# off the front will help the 60 FT.
I followed your advice, stayed with the cam and milled the new heads to 11,55:1
Made a few 1/8 passes yesterday and engine runs like a dream BUT now the converter stalls 5,600 rpms!
Could not shift fast enough, was hitting rev stop so I raised it from 6,300 to 6,800 (stock rods) but was a half second slower, no traction (1,9-ish 60-ft) but same speed. Was confused... Stopped, put in third gear, foot hard on brake and then gas pedal down while I looked on tach. Couldn't hold the car still, front runners was sliding. Did it four times and same result, tach did stop at 5,600 every time.
How is this possible?
Do I need a new converter? Or can it be modified? What should I look for?
