Fuel Injection
Has anyone used the Arizona speed and marine fuel injection unit that is made to fit under the hood of a 62, and if so how do you like it, does it perform well, it looks good but is pricey?
Thanks

Yes.
I-mail me.
if you want it to run right, you probably want to buy my fuel/spark map that cost me the price of their MEFI software plus some dyno time.
I won't charge you $800 though.
The spark map they supplied was waaay too retarded through most of the RPM range,a nd the fuel was waaaaay too rich. After tuning the program, I turned a 140 HP 327 at 7 MPG into a 300 HP (rear wheel) 327 at 18 MPG.
My fuel and spark map is specific to my engine, but you won't be off by more than a few percent on any other similar displacement motor.

I have no personal experience with the AS&M EFI units. But, if you are referring to their unit that has the air intake on the side, similar to an old Rochester unit, and your objective is to have an electronic FI system, then I think that is one cool looking modern FI setup! (it just needs SOMETHING hanging on the right side to simulate the old fuel meter)
Pricy? Absolutely! But if it will work as it should, it very well may be more than worth the price. By the way, when was the last time you priced a turnkey Rochester FI with dist??? You can buy 2-3 AS&M FI units for the price of a Rochester turnkey unit!
My opinion, go for it!

Herb, yes I read that you have to use the Vortec heads, but the heads that I have don't have the accesory holes in them so I was going to have to buy some anyway.
Thanks,

Wade,
Here is a front view of 57 Rochester FI engine. As you can see, it has the air meter on the left (driver's) side, somewhat similar to the AS&M FI, and that component on the right (pass) side sit the fuel meter. The AS&M EFI unit is plain on the right side.
This is the right side of the FI unit in my 56.
And this is an early Rochester unit that I restored which provides a good upper view of the fuel meter on the right side.

Mmmm, fuel injection.
If it all goes wrong with the plan to lower the Holley Stealth Ram, then I'm cutting the driver's side fuel rail into two and sticking the twin-58s out the side, just like the factory.

I have the AS&M BB unit and am very happy with it. I would go with AZ Doug and have him help you with the fuel mapping as the stock programing is generic and tends to be on the rich side. Another suggestion is to order yours without their wiring harness, I found it to be inferior to many of the aftermarket systems. I bought a Ron Francis wire works kit after trying to make heads or tails out of the supplied harness. I think Wire works sold the rights to their system to the Detail Zone. Give them a call and I bet the cost of their unit is compareable to AS&M's unit but the quality is much better.
Good luck
