Thank you for the responses.
I don't want a blown motor because I want it to be a sleeper. I am looking into an AED 850, cam is .560/.565 and 243/251 at .050 duration. Compression is between 10.7 and 11.02. Will probably use Skip White's 383 stroker rotating kit but I can't get them to rerturn my calls so I started looking someplace else.
I have the TH400 and the 410 rear, intake manifold is currently a RPM Performer Air Gap but can be changed if necessary.
