Stangatic

Hello All,
Took my 66 out last night and pretty much got fed up with dealing with a carburetors especially since I dropped about $250 to get it tuned last year.

I was just wondering if y'all would be interested in seeing a complete tech thread on the installation of the new MSD Atomic EFI System with a possible before and after dyno result. Anybody interested?

Sign me up. I have a 5.0 out of a 90 mustang that I'm debating on using the factory efi or going with an aftermarket one

ha! Same deal here. I have a 5.0 from a 89 sitting in my garage. Was going to change the EFI over but looked at the performance and what it would cost. In a nut shell, I wouldn't get the performance that I'm be looking for out of the stock 90 gt EFI system without modifying it quite a bit. (Port/Polish, larger throttle body, and new injectors since the stock ones probably see their days. Then I would have to spend the money for a hand held ) would be spending about $400 more for the MSD atomic EFI once all is said and done.

id be more interested in the dyno munbers before and after. The installation is simple enough.
