DELTA CAM wrote:hacksaw..... do you have a completely stock metro? if you do I will give you the free cam grind if it is the only thing you swap, I would like to be for sure the exact amount of mpg increase so I'm not miss quoting. The feedback I've gotten has been all bout 10 + mpg with cam swap. I'd like to know exactly how much is from truly just cam swap, plugs and filter change.
wanna get actual results soon so the offer stands for the next two weeks only, I will offer it to the next guy;)
Please post results.

Jon,
I took the camshaft out of the 1995 Geo Metro G10 engine today after work. This is the engine that I pulled out of my Metro on July 3rd. It had 145,000 original, untouched miles and ran very well. I have it wrapped up and will drop it in the mail and send it off to you tomorrow after work.
I'm still in the process of calculating a solid base mpg for the 1994 G10 engine that replaced the original one I pulled out. So far I've only got 1 tank through it since installation. That tankful was a 354 mile round trip I made to my parents cottage with me(210lbs), my 4 kids(approx 480lbs), two tents, 4 sleeping bags, and a change of clothes each. I calculated 43.92 mpg at a steady 70 mph almost the entire trip. I'm doing my normal routine this second tank...a mix of city traffic and freeway driving to and from work. Even if I receive your Xfi grind back in a timely manner, I would still like to do a third tank calculation before I install it. Since the engine only has around 600 miles on it as of today, I'm not quite sure what she's capable of mpg-wise. The ignition timing is still where the factory set it (5*), and as much as I'd like to change it a little, I'll leave it alone for at least 3 tankfuls with your Xfi cam grind installed. That way, we will get a good before-and-after comparison of the two camshaft grinds. I'm looking forward to this little experiment, and I hope we can all benefit from it in some way (me gaining more mpg, you gaining some advertisement, and everyone gaining some scientific results)
In the future, I'd like to re-create the trip up north with the kids again...same route, same miles driven, same speeds....If it can reach 70 mph with the new cam!!! hehehe...
Thanks again for your generous offer,
Hacksaw.
unfortunately i'm not in a position to pull my cam any time soon, 
so if you want to make the offer to someone else, that's fine with me.
