well, i've been doing some research on porting, and it seems like it's too easy! Are you people telling me all I have to do is pull my engine apart, buy a template and some good dremel bits and grind away? I plan to do a streetport on my 79 12a sometime in the future and was just wondering if it is just that easy.

[quote name='nismo convert' date='Aug 21 2005, 08:36 PM']it's easy, but dremels are teh wrong way to do it, i would use it for clean up, they are too small to port a motor.

Not in my opinion they're not.

for me, the Dremel is enough to do the intakes. i've been having a hard time with it on the exhausts.
i should be receiving a die grinder any day now, so i'll be able to make an informed decision on how much better die grinder works on the exhausts.

Grinding away metal on a housing easy. Getting the right shape, runner transition, and finish is the hard part. Templates only show you what size to open them up to. A template can't show how to do the real work that actually makes the most difference. It is possible to make a port larger and have it flow worse.
You will need a die grinder with some fairly expensive bits to do a nice cut. These generally aren't available at the hardware store. I've got some nice carbids and non ferrous bits that I use for various things. I only use a Dremel to go back and do finish work. It is possible to port an engine with only a dremel but it is also possible to cross the Atlantic in a rowboat. It's slow and difficult.
