All of these overpriced aftermarket systems...someone's got a good scam going. There are several good books on GM fuel injection systems, both port and throttle body. Corvette Fever did an article on a $200 junkyard TBI swap several months back. Lots of good info at this site: http://diy-efi.org/gmecm/ - there is a forum (currently offline) at gmecm.mine.nu. Thirdgen.org has a lot of good EFI info, too.

Vortec FI?

There aren't many after market FI systems that fit Vortec heads, so I was thinking about a FI system from a salvage yard.

What are my best year and model donor cars for a FI system that fits the Vortec heads on my HO crate?

If you go junkyard tpi, you can upgrade to an LT1 manifold for 200 if you have 1, or 400 including the manifold at LT1intake.com. They will suppport more horsepower if you want to upgrade later.... it would not need modified to fit your vortec heads.

The Lt1 intake can be modified to work on Gen 1 small block heads by redrilling the bolt pattern and adding a distributor mounting pad to the back for a distributor.

You can buy a Vortec TPI intake then use a typical TPI setup (plenum, throttle body,runners and fuel rails). The special intakes are about $400 new. Edelbrock and Scoggin Dicky sell them.

I agree on the vortec tpi manifold, also if you were to go the tpi route dont buy a system from these vendors junk yard , flebay, F/S section here ect. You get the idea youll save $$
