1984 Transam LG4 Sniper EFI conversion

Hi Guys. I have a 1984 Transam LG4 305 and I've had enough with the carb acting up.
I know they are great when they run well but i'm in the UK and no one knows anything about them.
I would love to upgrade to a Holley Sniper EFI. I think this will transform the car.
1. What Sniper EFI kit would be the best suited to my car?
2.Are they easy to fit?
3.Anyone have any experience they can share on fitting one or a link to another thread with a conversion blog on a similar engine car?
Any help appreciated
Thanks Guys

The sniper is a good system. A few things you'll need to do though before hand, an electric fuel pump that is high pressure, ensuring you have a return line to the tank.

I forget how the distributor on a 1984 works, if it's electronic advance or mechanical, but you'll want to ensure your distributor is locked and the pickup is wired to the Sniper for ignition control.

You probably won't find much info here, but a general google search will put you in good hands. Lots and lots of people have converted GM cars of that era to sniper EFI with great success.
