Am I going to ahve to change Carb settings?
Mercruiser 90 350 longblock with 217 heads (close to 083's) GM bowtie hi rise intake manifold and a 214/220 452/465 112 cam. I am running perfect with everything but the cam and over the winter this cam will go in. Will I have to change anything? Its a Non computer q jet. Thanks!

No Boat. Boat came with those heads and a small 200/204 398/400 cam.

Re: Am I going to ahve to change Carb settings?
If it's running good with the current cam I'd leave the carb alone for now and follow the old rule about changing one thing at a time.
Yes, you might need to do some performance tuning to the carb (slightly richer jets/rods and maybe fattening up the idle circuits slightly comes immediately to mind) but I definitely wouldn't do any of that until you see how it runs first. You may decide it runs just fine and never touch it.
It's definitely not going to be totally out of whack just from a modest cam upgrade.
