fast90 or 78 mm????? please help ok i got screwed on the used intake i bought. so now my problem is
should i go to the 90mm fast or the 78mm.
I am just worried that being i spray it.On a 346 CI the 90mm won't have the velocity to carry the wet shot. so what is the right choice here????

90/90 set up is hard to beat, it make good power and produces good results with those afr 205's you have. i have used 78 stuff on a all motor 346, and a s/c 383 and don't have any complaints. either one will make a good difference for you.

The runners are the same between the intakes. Only the mouth of the intake is larger on the 90.

I'm watching that storm on radar. Looks real bad as they are forcasting 4 inches of rain in NY. Supposed to be the worst storm in 14 years for Londg Island. Get your ride up on blocks and hunker down. Where exactly are you? Good luck.
