I assume it's an Automatic?
Get the motor up to 120-130 on jack stands. In gear , hold the brake , put it on the Convertor to load the motor maybe 5 6 seconds. 180- 190 temps cool it repete. Or take to the track and make 2 WOT hits.
Again, suggest that you use Maxima break in Oil.
Where is the timing set at? Locked out distributor advance? I would be very conservative with it. BB 402 Stocker start with 32 33 degrees go from there.

When you doing all this have a blowby meter hook up to it. When we had our B-Dragster you could spin the starter and if the float moved in the tube there was blowby!

Longer than care to remember. These is one is been the worst. I have had it apart 4 times hone it each time with the same results. The engine seem to leak fairly well 2.5 to 3.7 warm. Ran 10.64 at 128.00
