Considering I'm not a fan of the Performer intake (the RPM version is fine) and I don't know how well the heads are done (no mention of big valves or porting), nor whose cam it is, I'm going conservative and figuring 350-375.

That's a ton too much converter (about 1500 RPM too much), especially with that small a cam and a 4.11 gear., it will probably hurt ET, and especially MPH. In a good state of tune with traction, mid 13 seconds.
