What weight and brand is the oil? Some engines just don't like some brands, try another one.

yup i would look at oil break down try a race oil 40wt i would say she just big on main and rods clearances that ok for race or something getting the hell beat out of it. i have had some bbc that were a bit low at idle thats ok as long as oil psi builds thru rpm s do not worry about that 10 lbs for every 1000 of rpm you may want to look at your oil for gas you could be out of tune or no choke and small stop and go stuff your going to change out your oil more

Thanks Pat. I forgot that before I had a 30 mile one way drive on I-25 at 75 mph. Now it is 9 miles at 55 mph. I will give the oil change and 40 race oil a try. Before I had one stop light now several and eng temp may not be staying hot enough-long enough to "burn off" the gas the drops at start up. The stock presure pump went in just before I moved.
On the cold day's here you need to pump it a little 2-3 (cool days is one pump) with auto choke. I had also changed from a Holly carb to a Eldbrock which needs no excuess to flood the motor every time it can. I have a new Holly to put back on as soon as it warms up here.

the edelbrocks afb are good carbs they will not take hi fuel psi like a holley so if it floods you need to turn down you line psi
