how to smooth:intake manifold

How to smooth it?

cut off all the unneeded pieces and weld it

That easy?

Whats a good way to clean the inside?

de-greaser... simple green... crud cutter.... purple blaster

Damn.....I have to try this! What important holes do you not WELD? Pix?

the holes that you use you dont weld and the ones you don't use you weld lol

If you have a Webber Carb on it you can cut off almost all of your vacuum lines that run into your manifold.. After you cut them down you can weld it up and smooth it out.. Then it's just lot's and lot's of time in polishing lol.. I'll post pic's of how i did mine in a sec..

LOL!!!!
