I was thinking about getting rid of the TBI and installing a after market EFI has anyone had any exsperience with this

I didn't see the Year in your Profile so you might post that - a lot depends on whatever you decide upon as a swap will often entail new electronics and/or ECM. Presuming it's a TBI; ie an '84, and you want to upgrade to say a TPI, that isn't impossibly hard if you can find a donor with a decent harness and feeding that puppy through the Firewall isn't terribly difficult if you have the opportunity to pull it out of the donor for practice. If you want aftermarket, then the manufacturer's sites will often provide the info you want. And of course if you're in CA, you will have CARB rules to contend with, so you might bone up on that at the State's web site.

I know Holley makes a pretty decent injection+manifold system

No Go

I run a Holley 950 MPFI on another car and can say it is infinitely more user friendly than an OEM setup (I also tune my 96 myself using LT1 Edit).

The systems are far less complicated, but also don't quite have the same resolution as the OEM...very little to be lost really...

www.chevytalk.org has a healthy EFI section (moderator works for Holley for specific questions).

Good Luck!

I scrapped my crossfire induction and went to a Holley Projection Manifold with a 7.4L TBI on it. ECU is dynamicefi.com with a mod to adapt to stock CF harness done by speedtronics.net.

Haltech makes a plug & play system for the L98's
It's a little on the pricey side though, and it's just the ECU.

Why you ditching the system?
Limits of the ECU, the manifold, or both?
