Hey Mchell, Sorry for the lack of info, I understand that it's a long shot. I just thought maybe someone might have the same type of setup on there 400 and possibly shoot me some ball park #s. the motor was fully rebuilt at a buddy of mines machine shop in CA.
Here is a link to the cam I have the build sheet in storage right now. The paint, body, chrome, stainless, and NOS parts have taken so long(2years) to finish that I forgot all the motor specs and get them confused with my uncles jet boat specs and my cousins firebird specs. The heads are stock just rebuilt/refreshed, the intake manifold is an edelbrock performer(not the perf. rpm which is for top end IIRC). I'll have to stop by a buddy's house for the compression, I can't remember it for the life of me. When I sent it to my buddys shop I said build something in means of street/strip, since it was my everyday driver years ago
, so I know the compression is not extreme. The rear end is the only thing that has to be redone/beefed up in my opinion. Big pain in the ass to have the torque without the traction. I'm going to pick it up from the storage this coming week and hopefully have time to tune it and make sure everything is perfect. Hopefully I can find a way to fix up that rear end without dumping too much $ into, I've spent way to much on the car as it is. Sorry for the lack of info!
