I would guess you have a 440 engine there. That's a good thing.
you might try and retard the timing a few degrees. check the spark plugs for correct heat range and take a good look at them that they are burning correctly, might be running a little lean as well, check the intake manifold bolts for correct tourque and the bolts on the flange of the carb and that the air cleaner is clean. other that that you may need to upgrade to a larger radiator.
Intake was tight, but carb bolts were very loose. Still checking plugs. I'll let you know after my next trip if this helped.
Thanks
