any experience with Quick Fuel 450 VS Slayer carb on 273 ?

Hi, it´s been a long time since my last activities here...

finally i got the little motor running again after sitting for 3 years ...

again 273 wanna hear your opinions ...

as it´s getting warmer and spring is now right around the corner i was able to do some short test rides... and i have to say the 4160 Holley 600 cfm Carb i use at the moment is not the best choice...(pulled from an 383 bigblock and served well on my tweeked 5,2 Magnum) it´s partly to lean and partly to rich... and i´m tired of playing around with jets and power valves .. and beeing still not satiesfied at the end...

long story cut short: i´m thinking about buying one of those 450cfm Quickfuel VS Slayer carbs.... heard a lot of good storys so far...but not really in relation to a small engine like 273cui.

therefore, are there any users having experience with this carbs...

from my understanding it´s basically a holley with adjustable air bleeds, easy secondary adjustment etc...
