have to drop the whole rear assembly and exhaust. It takes a pro about 6 hours to install the new LPE or ADM system. Much easier on a lift than a garage project.

Dont have to drop the rear. See ADM thread. Did it the other day. Took me a bit longer than 6 hours though.

with just average daily driving (not WOT) do 85lb injectors use more fuel or are they just capable of delivering more fuel?

But well worth the effort

Hard for me to judge as I went straight from the 52 stock edelbrock injectors to the 85lb ones and turned up the power and was stroked. Then with e85 conversion my milage has really dropped. Add to that the fun of driving 700 plus hp and its pretty much 10 to 13 miles per gal average. Was it the injectors? Was it the larger displacement? 30 percent was probably the fuel though. Honestly, I dont think the larger injectors would hurt milage much unless you were giving a high demand for fuel and that is controlled by your foot.

yeah we looked at that approach and even thought about cutting a service panel but opted for the get it out where you can see it version...lol

Andy makes everything look easy though.

yeah...even at my current level I get the best gas milage in heavy traffic..haha

[hot ss]

the cradle comes down pretty easily.

My ADM install thread. Its pretty easy really. Found no need to drop the rear. Tank slides right out.

Sorry, Didn't mean to confuse. It was my thread on the install of the ADM kit. Very simple really.

No 85lb injectors would not use more fuel than the stock ones. I put 72lb injectors on because I am going to put a turbo on but that was a year ago and I have been using the 72lb injectors ever since. You just have to change your IFR(injector flow rate). You ECM will pulse the larger injectors less that's all. My injectors were at 85% IDC(injector duty cycle) at WOT and now they are at 33% so I don't use any more fuel.

At idle and part throttle driving your O2 sensor tries to always have a 14.7 A/F(air/fuel) regardless of the size of your injectors.

The larger injectors are just capable of delivering more fuel as you said. A lot of people think you can add bigger injectors and make more power. But, unless you are running out of fuel that will not happen because injectors are not power adders.




Fuel injectors don't make more power they just support more power.

Drop exhaust, drive shaft, heat shields, remove park brake cables. Remove front 2 cradle bolts & loosen rear 2 bolts & swing everything down. Gas tank will slide right out then. The whole install will take about 6 - 6 1/2 hours with wiring & mods.

Thanks

Not sure who that would be as there are only a few units out and the ones I know of have worked perfectly including mine.
