    That's a good question.........I have no idea. If someone could measure from their intake to the top of a really tall air cleaner that fits under their hood, that would be great. I do not have the car in Australia.......Thanks in advance.

    > I haven't bought a controller/ecm-yet. Maybe you can convince me,logic wise, to buy Accel vs Megaquirt ? Build is 350", (2) Thermoquads used as TBI's,(accel port injectors,160lb/hr.), located in former primary bores. E85 with up to 8 lbs boost,(blow-thru), via centrifugal blower. Water/alcohol injection as needed. Suggestions ? Thanks, roverman.:3gears:

    Just download both software packages and look at that first.
    How much hp are you expecting to make?

    Megasquirt is good but you can do so much more with the Accel that effects the DRIVING of the vehicle. They have some features the Accel doesn't but when it comes to a drivable combo the Accel is hard to beat, especially for the money.

    When you get closer, call me we can discuss your options, I'm happy to help.

    I thought the Megasquirt was less money?

    I know megasquirt is less money and if you can build the kit your self you can do it for a very low price... He is a dealer so he promotes his products thats all.

    Just for some info, the E-brock elbow comes in 3 shapes. 1 is basically 90* angle and is a generic fit all shape, then they have a tall "high rise" style for those with plenty of hood clearance, and finally they have a low profile 1 for those with low hoods.

    Also they are designed to accept the GM gen3/4 style throttle bodies. These have the IAT sensors built into them so no need to do any drilling for that sensor like our Aussie friend was going to.

    Necro post. On page two BObc I think talked about how generally nobody wants to Efi convert a dual plane. I’ve been doing a ITB setup on a newer car and know equalizing cylinder flow is important. With a dual plane I imagine some cylinders get more air than others because of the runnner length. Being the carb/fuel is before the split the cylinders with more flow at a given rpm get more gas pulled that way and the aft evens out, but not necessarily the power per cylinder. If you move the fuel after the split the computer will give every cylinder the same fuel causing rich and lean cylinders. The single plane is “closer”to even airflow to every cylinder so when they get even amount of fuel the afr is good. This is assuming your not doing individual cylinders tuning which in most Efi we can afford is miles away.

    On the factory dual planes I believe the factory varied the diameter of the passages to get the same flow through all the ports.
