Ah ok.
How come their site features ITBs on the main page banner but they don't sell any?

He used to make ITB, but was expensive.

When i converted the 202 to 36 - 1 CAS and 6 x LS coils i made a steel bung for the dizzy hole, and by all reports its done a perfect job...... but since i have my own lathe and a lump of alloy rod i had to make a lighter more shiny version :lol:

I also took the opportunity to try and make an injector weld in bung .... im pretty happy with it, other than i need to get something to linish the inside of it, its pretty rough, maybe the oring would conform to the finish but i dont know, i think as well the next one will be with different speed settings to hopefully get a nicer finish.

And lastly i am working on putting an ecu on a pre efi buick v6, and i wanted to make it run with a crank trigger that doesnt modify any of the stock engine parts, so i started with an MSD crank trigger wheel i was given, im not sure what the deal is with it, but it was massively out of round ... probably wouldn't have ever worked properly!

So i bored the centre out to fit the V6 crank hub and turned it down till it was round again, its now just needing some screw holes drilled and the slots cut in it, which i'll probably do once i work out the location for the sensor.

Thinking maybe make a bracket that comes off the fuel pump blank off plate and pick up a bolt down lower as well

You can also see in this pic below there is a dowl pin and 2 x timing cover bolts that line up perfectly with a later model CAS!

Probably best to ream the injector hole to size as it should be a lot smoother. Looking good though.

Have a play with your boring bar position and feeds and speeds, should be able to get a lot nicer finish than that. With a little o-ring crush there's no need to go overboard with the surface quality (unless you're planning on huge amounts of boost!). I've had good results installing injector bungs using epoxy (cold weld), saves warping things with welding.

Out of round? MSD? Never!

What's the plans for this motor? What's the bellhousing pattern like on it?
