250 is the good intake.

square flange holley is a 2 barrel intake with that flange on it, the runners and internals are the same as a small 2 barrel...

Are you allowed to modify the 250 intake, Ive got some that will make 20 more hp at least!

i looked today it is the 250 intake on my 355 the only work allowed on the stock intake is opening up the quadrejet holes to have 2 peanut shaped holes. it still has to have the devider in the middle.

i thought the holley flange cast intake was a 4barrel intake. i have not seen it he just called to tell me he had it.

The holley cast intake has holley 4 barrel bolt pattern BUT it is just put on top of a poor flowing 2 barrel intake. Its not going to flow as good as your q jet intake.

Just wondering...Where did this info come from? Have you cc'ed or flowed both of them? Or an observation of runner size? Curious...would like to have some #'s to back it up if you can point me in the right direction.
Thanks
