thinking rebuild..new block or keep old?

[fongo]

Hey everyone!
Need some feedback and recommendations here. I have about 134K on my 93GT, an the car runs great (daily driver, never gone past 4000 RPM's, well-maintained etc.) but I'm thinking of a rebuild when it hits somewhere around the 150K or so, and keep it as my "weekend" car. I was thinking of just re-doing the stock block with the Summit rebuid kit. Or is it worth getting a new block with new bearings, pistons etc.?? I can't spend more than $1500 (married, got a kid..well you get the pic) I don't plan to visit the track in the near future (probably not at all), just plain old street driving with a little kick and punch every Sunday or so. I do plan to get new heads, new cam, and probably a new GT 40 intake. Let me know.
Thanks
fongo
