Do I need to upgrade?
I got a quote from TMOSS to port my lower intake (says it's all I need now) and was wondering if I need to upgrade teh MAF and TB or will it suffice as is?

Still running the stock cobra MAF and t/b? If so, they should be fine. Have you ported your MAF or does it still have the bar in the middle?

If it's for the car in your signature, then you should be fine.

Port the lower, yes... but I'd also install a box-upper on it (Downs, cartech, etc...). It will really wake up the 306 especially with the X-303 cam and the Windor Sr. heads.

Tmoss said only the lower for this combo so that will be all. I have looked for a Downs before but had no luck. I remember you suggesting that before.

Forgot to mention, if the tmoss porting is still as expensive as it used to be, I wouldn't do it. I would set that money aside for another intake. I don't think you will see any gain whatsoever from the porting.
Something along the lines of RPM II would work nicely

Paying to port a stock intake (Cobra or not) is only good if you want to keep the stock appearance. Otherwise, the money is better spent on a higher flowing aftermarket unit.
