I ran that comp magnum cam in a stock 340 stock heads mild convertor ran 12.50s at 106. I still have that cam an lifters in a box there was a lot left in that package.
yea, as i remember that cam is well into the 250’s @ 50.
His 360 had a dome piston in it. That is why it liked so much duration. Would have run even better with more stick in it.
