Big bore carbs

well i think i need a new top end and thats like 150 if i do it my self so i figure since i was going to buy a big bore in the future now should be good and then i could sell the old one on craigs and get some of my money back but if i have to buy a 200+ carb in stead of a 70 dollar one itd be better for my wallet but i want the most power and still have a healthy engine
 
u can still run that carb on a bb kit and it will run fine, it just wont give "all" the possible gains....and always try to remember a heathy engine is all in how it is tuned and maintained
