My first half bridge :)

A dremel is slow, but less chance of making a major error.
I also like the tape covering the area you don't want to hit. Those carbide bits can jump out of the hole, one hit in the wrong spot can ruin the plate. They can jump without warning, even when you have used them for years.
When it comes to porting, getting in a hurry is the fastest way to make mistakes. Take your time, and it should turn out good. Just remember that the entire port area needs to be shaped as smooth as possible to acheive the best flow pattern.
I'm guessing you are planning to street port the center iron, since you say it's a 1/2 bridge. What type of induction are you planning to run?

I was always curious as to what the difference was between a full bridge and a 1/2 bridge. I didn't realize that the irons weren't port matched before now. I am actually going to begin porting my extra irons as a full bridge soon since they are just laying around and I want the extra practice on porting so that when I get the engine I plan on using as a permanent fixture in my FB (right now a street ported 12A is ready to drop in short of the clutch/flywheel/pressure plate needing to be put on). This was the guinea pig engine to see how well I can get a street ported engine running before doing a TII street port and bigger turbo to swap into my FB.

I can't wait to see the finalized project, Gabriel.

My trip to the states will take a big hit on my savings, but I guess it will be worth every penny.



I think I will finish this engine probably mid next year
