MM&FF Intake shootout

I'm still leaning towards the 347. I've already got ported TFS heads that flow almost 300cfm, haven't solidified a cam yet, either. Most likely at 280 or 296 Comp cams. Or maybe I'll just stick with an entire TFS upper
 
Oh okay that makes sense...I thought you were trying to add this to a 302/306 or something...

I would go with a custom cam if your going to pay all the money for your engine set-up
