I have a 92 caprice with a Gen1 358 I need an intake, and want to do a MPFI system.

I know it will bolt up to it, but...........

I have emissions,

So I need EGR.

What do I have to do to get EGR to work?

Next. Vacumn line to Master Cylinder, does the TPI have Provisions for that, or will I have to tap into a line.

Lasty Tv cable and Throttle cable, how to I get them to work, Longer line?

BTW I have an EBL so I plan on doing the Port Mod on it

There is a tech article on the main page of this website that lists the things involved in a TBI to TPI swap in a thirdgen. There are also several other posts made on this website from other people who have done the swap.

If you need more info on a Caprice specifically, you'll have to ask on a Caprice board.
