Port matching intake. Need suggestions
I have about 3/16" to take out across the bottom of the port. It needs to go all the way back to the floor of the intake. I am using a dremal but it is slow going. Used 6 bits to do the first port and it took about 45 minutes. Any better options out there? I don't have access to machine shop tools but have pretty much all basic hand tools.

Any hardware store will have ball grinders of various types. Chuck one up in a high speed air grinder and you're set. Here is one from Ace Hardware:

I'll also agree on the die grinder being the best option Kev. Even if it's an electric one!! W.W. Grainger has numerous coarse to fine cut 4" to 6" long burr's that are tailor made for porting aluminum. Summit & Jegs also offer porting burr kits if your so inclined.

It seems they were recently on sale for $29.99, but they keep the prices bouncing around. I wait and buy when the price is so low I can't afford not to have the item. I bought one at $29 as a back-up to my old Craftsman unit. The air die grinders make too much noise for me.

I just recently managed using a dremel bit, the cutter type that looks like a cylinder with two sharp blades sticking out and quarter inch diameter. I only went back an inch and a half though. Still had to emery smooth everything.

What you need is an electric or air die grinder and a carbide burr designed for aluminum. It will take you only minutes to do what it took you hours to do with a dremel tool. Where googles / safety glasses as the chips will fly!

I got to thinking, were are all telling what is needed. But what we are failing is to tell you that you might be dorking up a good intake. For intakes to work, that is have any tuned ram effect has to get consistatly smaller all the way to the intake valve.
Going from small intake track to larger head causes fuel/air sepparation.
3/16ths is alot of mismatch.

I used my Makita 25,000 rpm die grinder for years. I also bought an air die grinder. Much cheaper if you have air tools. You can buy aluminum or iron cutting bits with shafts 6 inches long. My favorite aluminum bit is a one inch long conical in shape.
The bits are what cost all the money. Trying to use sand stone is stupid

And don't forget...the port opening has to be blended smoothly 1.5" up the runner. Here's a great article for those thinking about doing it.
