Hasa any one used the holley pro-jection fuel injection system..says it is for a 79-82 258..Curious..its only 700 dollars?

I had a Pro-Injection set up on a small block chevy a few years ago. It sucked! Constant tunning problems. You can find my old system in the dump.
Maybe they are better now.

Yep, I have a pro injection setup on my 304. 670 CFM 2 barrel. Pretty easy to hook up, PITA to tune. For a really good setup, look into the howell's setup. Only prob is, it is around $1200. But all replacement parts are for the S-10, easy to get.
If you do decide to go with the pro injection, get the rich/lean indicator and the close loop O2 sensor. The rich/lean indicator will help BIG time in tuning, and the close loop will keep everything running smooth throughout different altitude and barameteric pressures.
