Webers are ok but they will not out last a Stock Aisin Carb. , just my opinion , and I know others will swear up and down that Webers are all that but in my opinion you can not beat the stock Aisin . They may not out perform but they will out last if well maintained !!!!!!
now how do you know?? you had your weber on your truck for maybe a week
and you never did have it jetted to match your 20R
You can get an adapter to run a holley 500cfm 2 bbl, but I agree that you're better off sticking with the stock 22r carb. I personally run a weber 32/36 and do not particularly care for it, especially if you sneeze or lean too close to the door.
500cfm on a 22R
i hope its got a stage 5 head and cam on it
ive had my weber for about 5 years i guess, had some issues when i bored the engine to .060 but after installing some bigger fuel jets it runs perfectly
in fact Insane06 commented on how smoothly it idled up after warming up from a cold start
carbs must be tuned, i dont know how to tune a aisin carb but i DO know how to tune a weber
