I have a small block chevy with a 6-71 blower. My problem is that it keeps
on blowing manifold gaskets. Has anyone run into this problem? For some
reason it will run fine for about 10 minutes and then it will let go. The
gasket is between the blower and the manifold.

Check both flanges for square. Check the manifold for blockages, check
your intake valves for proper opening. Half open vaves will cause back
pressure, check for bent pushrods, bad lifters or a dead cam lobe.
