Holley, MSD, Edelbrock etc... Anybody run any of these? Pro's and cons. Which is best? Planning on using it on a 502

Are you wanting rail injection or more of a tbi set up? Fitech or holley sniper?

I have not tried one yet. From the old car forums I am on it sounds like the newer version of the Fitech works well. The earlier ones had some issues. I do not know how to tell the old and new apart. I am planning to use the Holley on my son's 383 Chev because it sounds like overall the
Holley owners have had the best luck. I plan to go with in tank pump not inline.
The engine isn't built yet and the car has been waiting for paint for 13 years so they will likely have something better by the time I get to it.

I've been doing a lot of research on this. FiTech seems to be the leader. Big issue with any of the TBI set-ups is they all rely on MAP sensing. If you have a big cam and less than 10" of vacuum they wont tune well. Get a FAST sequential port system.

I use fitech. I have an older one 30001 series. It works well. Im runnimg 17" vacuum too. But the tune is easy. Couple things take time like dfco to figure out. Holley sniper is good, it just wasnt out yet when i got mine. On the chevelle forum there is a guy that has both and he did an awesome write up comparison.

I'm running the Edelbrock TBI setup, but i don't think they make it anymore.

I think they still do the multi port injection but its 2500

Holley sniper on the 406 in my 66 Chevy II. I haven't driven the car yet due to paint. It has been fired up off and on since I've installed it.

There's quite a few very happy Fast XFI users around here. Great system, but maybe more high endie spendy than you had in mind.

For example.... https://www.fuelairspark.com/xfitm-electronic-fuel-injection-kit-bbc-up-to-1000hp.html

Otherwise, the other end of the cost and complexity chain would be... https://www.fuelairspark.com/ez-efi...e-control-system-master-in-tank-pump-kit.html
