Carb size vs intake question

[KAMIKAZE]

OK so I currently have a fireball racing billet intake and pwk33s

 

Will pwk35s fit in the same intake boots ?

 

Are pwk35s the best size for the 421 serval ?

 

I ask because some sites advertise intakes for 26-35mm or 34-39 ect

 

Is it a case of buying new boots or is the whole intake larger or will they just fit straight in

 

Just looking for a straight answer as seems to be a bit of conflicting info when I search around

with a 421, atleast if i had one, it would have pwk 39s on it. But 35s are good by all means, regarding the intake boots i believe they would fit because i have also seen the boots advertised like you first stated

33 & 35 pwk use the same boots.

 

The best size carb on that motor will be preference as the larger the Carb the more mid you will loose but gain top end.

Plenty of guys including myself are running 35's on 421 motors with great all around results.

Best place to order new carbs from ?

33 and 35 PWK are the exact same carb, except the 33 is not bored out as far. If you look at the 33, you will see that it is not bored through the center. This is so the needle jet is still at the bottom of the bore.

So is it a worthwhile upgrade ?
