What carb do I need for short dirt drag?

[Common24]

I recently purchased a Herr racing super cub 472 topend to use with my 4 mil and looking into changing my carbs. I am currently running a set of 35 Keihin airstriker carbs on gas that I ran with my stock cylinder setup. Can I convert Keihin Airstriker carbs to alky? Who can do this mod? Stay with gas or switch to alcohol? Will I need a bigger carbs to run a 150ft to 200ft dirt drags?  any info would be appreciated

You need these if you are going to alky >  http://bansheehq.com/forums/index.php?showtopic=170298&hl=

Bitchin carbs sprinkler!

OP, there are a lot of guys out there that can do alky conversions on carbs. I'd steer clear of converting your air strykers though. Maybe some 39mm PWK's. but that means you'd be buying new carbs, then sending them out to be re configured, you might as well grab up those carbs sprinkler posted. But if you are absolutely adamant about new carbs send them off to A&S, K&T, Packard, or RDZ.

I didn't order the kit from Kevin directly bought it off here in the parts section to a guy goin to a longer stroke. The guy that ran the motor ran 500ft with a set of 39s on race fuel. He said he couldn't say what size carb would work best in 200ft. I will try to call Kevin tomorrow and ask just trying to get insight on what other people have used. Most of the tracks here in Kentucky are all 200 with a occasional 300ft. Most of the county fair races I go to with my 450 quads I take the banshee to play around on. All of those are around 150ft.

If drag racing bigger wont hurt. 39s will work and no shortage of them on alky.

39's all the way imo.

What 39s do you recommend Bobby?
