I’ve run both on my car. I would say the Summit seemed to feel slightly better if I had to pick something out between them but not earth shattering. I went back to the Edelbrock only because I have a tuning kit for it. The Summit I forget either was rich or lean at part throttle and a jet kit was like $100. What I was disappointed by theSummit is a lot of rough areas inside the boosters that were not deburred. I feel there’s a lot of room for improvement. Over all the Edelbrock is made and finished much nicer.I’m pissed at it for stalling in the stop box at the autocross. A known problem with the Edelbrock. I tried the off-road float needles but it didn’t make a difference.
I’m not sure if it’s flooding or starving under the hard braking but either way it’s unacceptable to stall and not be able to move when you have a car behind you.
Plus if I can get a bit more response I’ll be happy.
Based on my AFR gauge I feel the Edelbrock is tuned pretty well and makes a really nice street carb. Hopefully the Summit performs better on the autocross track.
