360 Intake on a 318 - What To Expect?

ok, so your wanting to take the street dominator off, the tired 318 that your wanting to use for a driver motor, and swap it with a iron 360 inatke till you get another motor built? correct? well if you are, obviously there's a port mis match that you already know about, then your gonna be adding a good 30 or 40 lbs (they're heavier than one would think). i really don't see it doin much,if anything. i would almost bet that it would hamper performance, with out even knowing any of your other info
(vehicle,weight,gears,etc.)

I have heard the cast iron 360's are "ok" intakes if thats all ya have or you wanna go with a strict sleeper build.. i also heard they make power too around 5,000 or so.
I have 2 holley street dominators PN 300-7, i've found em to be good little intakes for a stock, mild 318. I also have a stock Iron 360 4bbl intake too, if it wasn't goin on my old 318 dodge farm truck in the near future (tired of messin with the old wore out carters i have) i would have probably scrapped it by now. if you already have it on there, i wouldn't change it, but it's only my oppinion. maybe someone else can chime in later, and tell ya more than i can..
