Fantasy engine build.

Ok,this is just a basic outline of what i would like to do with my engine.
I have a clean 40 over jug-that i am looking into self porting,as soon as i have a better understanding of what does what. Then i wanna run a vforce 3 reed's, a reed spacer, yz 250 carb, shaved head , +4 timing , uni filter ,a good low-mid head pipe, a good muff, 14/40 gears ,20" tires,and aluminum wheels.
Assuming that i do a good port, considering all the listed specs, what "should" my bike be compairable to ?

it's a good plan, but i wouldnt call it fantasy...but thats not fer me to judge...power wise you would be able to easy keep up with the 400's fer sher...trash all 4-strokes under 400cc easy...if you port it right and do a good job you could give a stock 450 a run...prolly not win but you could give him a scare off the start...

I don't think its going to run very good with a yz250 carb on it. Too much for a 40 over cylinder, imo. I'd look for a smaller carb

For a guy as broke as me,yea it would be a fantasy-i could barely afford to get the blaster,and it was FREE !!
Any how,i wondered if that carb would be to big. What other carb might i look for for a little added pep ?
