TBI upgrade

[razor1115]

I have a GM 350 1994 TBI in my truck. It will be time soon to freshen it up as the truck is still in excellent shape. Stock was 225hp. The newer Vortecs, I believe, are in the neighborhood of 285-300hp? I am not proposing a head swap to Vortecs with the manifold change or anything like that. I AM trying to find the limitations on adding power to my current set-up. I would swap in a little more cam with the refresh. Probably a roller cam and possibly rockers. I do not know and cannot find the limiting specs on my throttle body as well as the MAP sensor and computer. Does anyone know these items or direct me to a source of info. Surely someone must have already done a rebuild like this retaining the stock fuel injection, but bumped up the power without overriding the TBI, computer?

 

Any help would be appreciated,

Thanks
