Will a simple 01 Cobra computer swap solve the problem?

It's hard to say as some have worked (naz) while others haven't.

Thanks for the quick answer NA_SVT, now I have much more reading to do this weekend. Since it is to hot to mess with the car.

I drive through there all the time when heading to Tyler. I think you are about 50 minutes away.

My parents live in Tyler, I have never lived there, not many good tech jobs there.

I beleive the Holley systems costs around $1700.

You can also use an MSD 6Mod to control the ignition while letting the stock computer handle the fuel duties.

My choice would be the holley systemhttp://www.force-efi.com/holleyefi.htm. You can use the stock computer to power the dash gauges if you wanted to keep them.

MGannaway, I forgot to mention the holley system to you the other day.

Actually picked up 70rwhp with the extra rpms and sully, still thinking the hpp upper is hurting it but that's the price to retain the shaker without cutting the shaker. Thinking the best ignition is a distributor! Don't think that is very expensive either.

What upper would you think makes more power than the hpp upper? I still havent ordered an upper. (i have the sully forward facing but figured the hpp upper would make more power)

Wilson elbow would flow better

what makes it not work with the shaker? just size?

[st0ck Mach 1]

You would have to cutout the bottom part of the shaker because of the height then mount it to the hood, I was not willing to do that.

screw that...ill go hpp

Thought there was a big difference between the auto a stick computers and the number of calculations per second they can perform. Stick being able to calculate at a higher rate and thus the ability to rev higher with fewer issues.

I may be wrong, but that seems to be lodged in my memory banks for some reason.

I've pulled the stock mach pcm to 9, 000 rpm but requires ignition system upgrades.. I was running a distributor with it.. still found it glitchy with an auto in high gear but it can be done

I'm no computer expert by any means, but I believe the more systems you can shut off in it the better it will work. Josh at JL Tuning has also gotten the computers to work at higher RPMs but I don't believe he's been 100% successful...but I could be wrong.

More systems inside the computer? Or like more stuff in the car? If I was ever racing the car I never ran the radio or blower motor etc and usually had minimum gauge cluster lighting.

I was thinking of stuff like the EGR, knock sensors, ignition (f you plan to use a distributor or 6MOD).

Knowing your build, I recommend the Holley system and use the stock computer/sensors only to control the instrument panel. st0ck Mach 1's car is a good example of what an aftermarket system can do for a high RPM engine.

Has anyone though about feeding the Sullivan from the bottom to maintain the hood clearance? There's plenty of room underneath it to allow for it...just thinking outloud.

I've though about doing that on a 5.4 to allow it to fit under a stock hood.

Seems like you would have to come thru the firewall to get there unless you move the alternator...just thinking out loud also!

yup exactly why I use it too. If I ever get the urge to try the Wilson with the Wilson body(I have it), I will get an old hood to cut up...not cutting a shaker!

Well I will def be looking into it. I plan on running slow for now during the engine break in period. Once I get a faceplatted tko 600 then ill be looking to swap to better ignition.
