Hello,
I have a 1977 Chevy k10 pickup that I am restoring, it has a fresh 383 small block with a mild cam. I am thinking about going with a triple deuce carburetor setup rather than a single 4-bbl carburetor for looks/performance. I understand that the single 4-bbl would be easier to set up and tune. Would a 3x2 set up perform better then the single 4-bbl?
Thank you
6 barrels would allow more fuel/air than 4 barrels, assuming the barrels were equal in size.
Yes, the triple deuce setup will perform better, but the trick is to have all three carbs tuned and and the linkages setup up correctly. I'm sure there's a lot of videos out there.
Jetting and synchronizing three carbs is going to take expertise (or a dyno). Why not spend all that money on a good, reliable aftermarket fuel injection system?
I decided to stay away from fuel injection because I read that the aftermarket systems use there own brand of sensors. I was worried that if I had an issue on the road parts stores wouldn't carry there brand of sensor. I thought it would be easier to find parts for a carburetor if I had a problem on the road rather then having to order a part from the aftermarket injection company.
Thank you for your response.
Fair enough. But if you have a carburetor problem out on the road, no parts availability is going to help you either. If you pick a reputable fuel injection manufacturer (like Holley) parts are a day away. And if you get the jetting wrong on the carbs, the result is usually burned pistons, which means an engine rebuild. The self-learning EFI systems have eliminated all that.
