Re: 70 c10 project

The runners will have a set of straightening and enlarging balls run through them enlarging them to stage 3, or about 1/4”. I have a 90-92 speed density ECM, and I bought a custom speed density Harness from Larrys Electric. I also have a weld in O2 bung and a knock sensor.

Re: 70 c10 project

Looking good! Are you switching over to an electric fuel pump as well for the TPI setup?

Yep, just didn't see you mention it and saw that it was just a few months ago that you all put the Edelbrock pump in, so was curious .

Re: 70 c10 project

Do you have a plate for the EGR blockoff, or going to block it another way?

Re: 70 c10 project

Are you referring to the port in the middle of the manifold? I was gonna have Michael make a block off plate.

Yup. I bought a manifold once where the previous owner just caked it with silicone, so was going to recommend a plate of some kind instead .
