Do I fix it or rebuild engine?

Gotcha.

You can just keep the TBI and upgrade the injectors and intake manifold.

Dams, that is big. Just make sure the intake manifold can flow that much.

The 700cfm is cheaper cause I'm getting charged a core charge.

Which is better boring out the current intake to 2in or use a carb intake w/TBI adapter?

HUH???

Ok, found a intake that refurbished and bored to 2in for 130 bucks and 700cfm throttle body is 250 bucks.

Now whudda you gonna do about heads Dave?? TBI heads are not going to flow near 700cfm. IF you are gonne do this, do it right, don't just be a parts swaper and waste your money.

I'll have the TBI heads machined/bored out to work or use vortec heads. I was told vortec heads will work with the 2in bored intake.
