new engine

[Speedster]

hey nitro people. I am thinking of getting a new engine for my savage x, was thinking the 4.6 in the optional parts list. was just wondering if there was any other engine that you guy's would recommend that is cheaper more reliable etc, plus more power, less money that kinda stuff. I also was wondering about changing the clutch bell from the old to the new engine, and wondered if i should put the optional cb that comes in the box with more teeth believe it's 17 teeth. will it still pull wheelies with this cb on cause i want the wheelie. lol

I was also wondering if the axial .32 would fit in there i noticed that the carb was made backwards to the stock hpi carb cause the throttle valve what ever it is called is on the other side, can i use this Betsey, and is it a better buy? Also wonderd if i would have to beef up any drive gears or anything along those lines.
Any comments are appreciated thanks,

i got a used sirio .27 recently and it has great low end power and plenty high revs for the way i use it, but those two you are looking at are good.
plenty people can give you more details on them.

can anyone tell me about how to change the clutch bell from one engine to the other, i've never taken it off before and have heard stories about it. just was wondering what i have to do and if i need any special tools. I was just concerned that when i took the clutch assembly off that the shoes would spring off or do something but i duno.
