I totally get what your saying but even though all that would do is lower the .050 duration which would make the cam closer to the specs of the cheater cam. |
Very true. |

| based on numbers given, of your three choices the FK-41 still looks the best to me with either 1.1 or up to 1.3 rockers. that cheater cam looks pretty soggy with relatively high advertised and nothing @ .050" |

Yeah but the choice is harder because I am tying to go economy.
If I wanted to go fast i would just go all out but I am shooting for 30MPG.
I think the displacement will give me tons of power its harder though picking a cam when you want to save gas.
Its funny I was talking with a buddy today about how much easier it would be if I was building a small block Chevy because if I didn't like the cam I could just change it but with a VW I have to break the whole motor apart to change the cam. It makes for a much harder choice. |

i honestly think your making a mountain out of a mole hill with this cam descision. your state of tune on the engine will affect your MPG more than the difference between the few cams you have listed.
if your engine isnt tuned properly it doesnt matter what cam you run youll get shitty results. bottom line.
heck if mid 20s can be seen form a 200hp motor w/ idas 30 should be a cakewalk with small displacement and kadrons or 36 dells
just measure your deck, set the compression to what your cam likes and tune the timing/carbs properly and youll see 30mpg unless you drive like and asshat

| the comments Grimace made are about all that needs to be said, beyond that I would just add that smaller cams require more conservative thinking when considering compression ratios. |

Your probably right but this car has been in dry dock for 4 years and I am just trying to do everything right before its on the road again.
It has all brand new brakes with dot 5 fluid suspension and shocks are new. everything that I could fix I have and I am almost ready to drive it so I want to make sure everything goes right. |

I had a funny reply.
The reason i am building this engine is so I can drive like an asshat and still get good gas mileage.

But you can't drive like an asshat with a 28PICT. My 1915 turbo gets mid 20's, and it's fast enough to kill me.
