The difference between the tri power and regular carbs
Hey, I have notice that on some vette engines I see there is the triangle carb that says "tri" power and some are just regular round carbs. Was the tri power carb an option?

Hi
Tripowers are a great setup and tuning is rather easy. Really it is only a question of correctly adjusting the linkage.
Tripower are cool looking and last but not least are the carb with the best fuel economy when driving correctly, but with fire and lots of power if required.
This because the primary carb ( center ) is rather small designed, hence regulating a correct fuel/air mixture in low RPM ranges and if required, you add 2 ea secondary carbs and open the breath right up.
Best carb for my 68 BB I drove and I tried 650, 750 and 850 DB B4.

Hi,
From the very beginning Corvettes have often had multiple carbs.
Even the original 53/54/55 6 cylinder motors had 3 carburetors. Then for a few years there were optional engines with 2- 4 barrel carburetors (56-60?). In the mid-sixties 3-2 barrel set-ups became popular (GTO, Ford, Dodge, Plymouth cars) so along came the 435 hp cars with 3-2 barrel carbs.

Alan

I believe the 68 set up on tri power had all 3 carbs at 350cfm for a total of 1050. On my 69 GTX, the center carb is 385 and the 2 outboards are 500 each for a total of 1385 but that does not make it faster than the Vette.

Emissions and fuel economy caught up to the three deuces. You could still get a 440 six barrel in a 71 'Cuda and the 340 six barrel in the 70 Challenger T/A and AAR 'Cuda. I think the six pack died along with the muscle car. 1972 was the beginning of the end.

EFI eliminated the need for carburetors. Carbs attempted to manage fuel flow efficiently throughout the range of engine use; some did better at it than others. A tri-power setup which operated mainly on the center carb with mechanical kick-in on the outer carbs at WOT was economical and powerful. For a carbed engine (which needed that much airflow), tri-power was a great option but was much more expensive than a single 4-barrel carb.
EFI and electronic controls made carbs obsolete (except on vintage cars, of course).

Well....I once had a '65 Pontiac Catalina/Ventura with a 421 HO tri-power engine that would stay with the 427's pretty well.... (but it was still a tri-power!)
