Another advantage to having the PCM drive the fuel pump is if the car stalls it'll cut the pump. That is a great safety feature if there is an accident where a fuel hose may be broken and potentially a fire. I learnt that from motorsport scrutineering but the logic works anywhere.

I never even considered that. Thanks for the info. I should be up and running in the next month or so. I need to pick a cam. L96 or LS2??? I may add boost later on, not sure. The L96 shares the same specs as the LQ9 in the in the article but is a single bot cam.

Personally, I'd put it in bone stock and work out any swap related issues/bugs without also having to wonder if the cam/tune is contributing. Then consider doing cam/boost/etc once there's some miles on the swap with everything working as expected in stock form.

Hi zach4200. Thanks for your reply. I plan on running it on the stand, first with the stock cam, then the upgraded cam. I plan on putting it in a Mustang, I know it will fit, butt tight. I use to own a 95 5.0L when it was new, was a fun car to drive in my 20's. Had it 10yrs. Ya I'm old as dirt LOL. I'm actively searching for a donor. They pop up from time to time. Have to be fast. I missed a nice 1 a couple months ago. Would of been perfect. Was mint, but the engine was dead. Basically I'm looking for a 94 and up, mint or VG condition mustang with a blown motor or tranny.

I want to get everything worked out on the stand. At least a good idle. Once it's in a car everything will be tight and would have to probably partially pull the engine to replace the cam.

Thanks again.
