FS Soon - Watson small tube Headers - Page 3 - ZR-1 Net Registry Forums

There is no modification to the dipstick needed with these headers. You use one of the stock bolts and spacers and you are good to go. Plug and play deal here, no joke. I think Dom and Lee can verify that.

Thanks.

Hi Jim,

I can't answer your question for sure on the Watson's and if they would affect your 402 build. I am thinking maybe Kevin, Todd or Ryan can pipe in here with their experience with headers if any. Also, maybe a call to Marc or Jeff would be in order also. If I remember right your build will have cams and larger throttle body also so I am sure the chip won't work for you.

I don't have a exact number of HP loss, on a 402+ ci. motor. It could be 5-25hp, just not sure. Maybe Marc might know, I think he has done back to back dyno runs.

Jim only 600hp...... I'm betting more. Take it your not going to hit it with the 250 shot

No nitrous for me, but I don't want to choke things up with a tiny exhaust. After the headers I plan to run entirely 3 inch exhaust, including mufflers that have 3 inch passages throughout. It may be a tad loud, but I'm getting old and deaf so it won't matter. For headers I guess I need the 2 inch primary pipe Stainles Works. Anybody have a set of those for sale?

Ah Jim, they aren't that tiny. I probably would hold out for the bigger tubes too.

Me either. This is a steal on coated headers. Everyone who is thinking about headers and passes on these is going to be kicking themselves
