Carb isolators.

[madera cruiser]

Anyone stack up unmodified isolators? Rules say unmodified, not how many.

My guess would be NO... I cannot see an advantage to that because you have a D port shape on exit side and a round entry not good. If your looking for extending runner length even if it was legal that would be a bad way to get it.

How about the carb side isolator unmodified and the head side isolator blended to port size?

What are you looking for longer runner length or heat isolation ?

Runner length. just a thought. May not be worth a damn.

Don't forget about carb stud length so a longer runner will favor more low / mid range torque i'll assume that is 'swhat you want if that's the case i would look for it in a cam instead.

Rules don’t say you may run more than one either

That is the point. It doesn't say I can't. This isn't AKRA or NKA.

Generally you want the shortest intake tract .
Tuning for a certain rpm tract length can be adjusted .
