I've looked at Bigs. GREAT carbs . . . for about $1,000 delivered. And then you have to tune it. And then you have to . . . eh, you get the picture.
Here's what I do. I've got a bulletproof all forged 500+ hp 8,500 rpm redline screamin' demon that . . . I drive to work. On RARE occasion, I may do some road course work, but, for the most part, it's going to go to work (20 miles or so) OR do some interstate runs 300-500 miles (I'm running a 3.00:1 rear for goodness sake!).
I don't street race. The car's got a baby seat! Basically, we built the motor in '93, it's got 160k on the odometer, and we MIGHT have to re-ring her this year. Same motor and everything was at the last TWO 10 year Mustang shows (30th and 40th). It's way more than I need, BUT it keeps the young kids in the ricers quiet. It's my "anti-street race" car.
Anyway, like I said, I'm a mechE, so I work on crap all day long. The LAST thing I want to do is come home to retune the carb that I tuned yesterday because the tune from the day before wasn't good. I live in West Tennessee. In one week, we can have an ice storm, a tornado, and then a heat wave. A 50 degree swing here isn't unheard of, so it's dern near impossible to "dial in" a carb.
I've heard that BG Demons are good carbs, but I've also heard their recent QC has been crumby.
I can't believe that no one makes an "easy" 351W EFI swapout. If I had a 302, this would be REALLY simple.
Bummer.
Odds are, though, as soon as I buy a carb, somebody will make a cheap EFI kit for a 351W . . . without a doubt! LOL!
What I'm looking for REALLY is a carb that doesn't get flakey on me.
