header evac

[hvychvy]

I have a 1983 s-10 w/ 383sbc, iron heads "nuthin fancy" just a weekend toy. I have purchased the moroso header evac kit and I need to know how far from the collector this pipe inserts should be installed. I am using the hedman s-10 shorty headers with a 3" extension coming down and turning out under the door, this is a race only setup. I appreciate any help, thanks in advance.

Generally you put them within 2 or 3 inches of the header flange inside the collector.

I'd say either right before the ninety degree bend or right after it where the collector is straight.

Thanks, that's what I thought just wasn't sure, so I came to the RJ braintrust.

If you have the shorties, I think you will need to put them in the pipe further downstream, after it makes the turn from the firewall should be fine...
