Here are some pictures of my intake manifold before, during and after the porting and milling. It is a perfect fit for the Arrington 90mm throttle body now Thanks for you help on this Cam and Jonzmgnm.
Put the throttle body on to check if I need to work on the porting. I need to remove just a touch in the 4 O'clock position but its just about perfect Not bad for a goof, lol.
Did it all by hand. Wasnt bad and I enjoyed doing it. This was my first time trying something like this and for any beginner its doable. Here is my last pictures I swear, lol. Just finished polishing, its super smooth.
what did you use to do the hand work??? dremel or something similar??? well done. not sure how you were able to keep things symetrical. any tips???
I started with a die grinder on an air compressor. Then I switched to drum sanders on my drill. I just took my time and used that paper gasket I made as a rough guide. I went around and around and around, lol. Made it easy to keep it round Just take your time, biggest tip. You will need to seal it with a gasket or sealant. Once you remove the oring groove, you wont have a way for the stock oring to stay in place. Not hard and its a $5 tube of sealant and you are set. Thats next
