Biggest Cam & Still pass e-test?
 

Would anyone know what is the biggest cam I could run, and still pass an e-test in Ontario? Besides an FMS E303. Thanks.

Welcome aboard and one of the experts will be along momentarily. Good luck with your project!

1LOW03GT ...... over to you.

E303 or B303. If you look at the Ford racing catalogue I believe those are the only two emission certified cams.

small choice for sure. Move out here no e-tests lol

^^^^ Gods country!

Mine has a b303, passed fine at 40 roll, at idle wasn't even close, way too much fuel. car has heads/cam(obv)/intake, no pollution pump and mac shorties. Possible to pass at idle with tuning? Sorry to high-jack thread but this may help you too.

retry your test, but pull the spout connector just before it goes in, and add 3 liters of methyl hydrate. garauntee you will pass the next test that way.:shakeit:

Spout connector? Sorry Im abit of a newbie. Yes have heard about methyl hydrate though. Thanks for your time. Hope this is helping original poster too.

yes it is that little dead end plug that is attached to your distributor:

Attachment 15020

See the plug in the blue square? unplug that little gray thing in the end of it. what that does is prevent the computer from advancing the timing, which will lower you emmisions by a ton.
