Mopar 400 block 8 sleeves

Well, there were problems on the dyno, my radiator hose raptured during 1st pull and we had to stop. Pull stopped at 4800rpm and it made 520hp at this rpm and 590 ft lbs at 4500 rpm. I will come back to the dyno when I fix the car, I also need to get rid of transmission leaks. Hoping for 700+ with smaller cam and close to 750 with the bigger one.
Engine was setup with only 32 degrees advance for start, I am not sure how much is too much in this case. I saw guys running 36 degrees advance with these heads. I guess pinging will limit timing, I'm using 100 octane gas.
Will report with more info.
