Believe it or not, this will work on 351 Windsor based lightnings. It is an old trick that many budget conscious Lightning owners have done for years.

Im getting ready to install this with the sve intake, but my studs on my old manifold were like rusted welded on, question is where can i find the right studs for the intake, T/B, and egr spacer? Been trying to look but no luck. Any help will be appreciated, thanks!

Same thing happen to me. I took the nut to Lowes, figured out what thread I needed and bought grade 8 bolts for I think .89 each. I dont recall the length, however measure whats sticking out of the upper intake and add a 1/2", thats what I did. They have been working like a charm!!!

There is no direct correlation between injector size and throttle body. The airflow capability of the engine dictates the sizing of both. For your typical heads/cam/intake/exhaust 5.0L, your current setup is more than sufficient. To get more help for your specific engine combination, please contact one of our customer care reps!

The TPS is not included with this throttle body. You can reuse your existing throttle position sensor, or purchase a new one, available under part # BBK-1684. The throttle body does include new TPS attaching screws.

It's not necessary to drill a hole in the throttle plate with this throttle body. That was a tuning trick that was handy on stock throttle bodies where there wasn't a lot of adjustment allowed from the throttle position sensor. Drilling a hole allowed you to let a bit more air in without messing up the TPS setting. Drilling a hole is an option, but you can also adjust the throttle blade, then use the adjustable throttle position sensor to reset your TPS voltage to compensate for the new throttle position. Many times, idle quality suffers when the throttle blade is too far shut, causing the car to rely on the idle air control motor to make all of the adjustments. The idle air control motor is designed to make finite adjustments to idle only. If it works too hard because the throttle blade is too far shut, it often leads to surging and dying issues. By opening the throttle blade a little more, the IAC doesn't have to work so hard. Set your idle to 8-900 rpm with the throttle blade adjustment screw, and the IAC unplugged. Once you plug the IAC back in, it will adjust to the new idle rpm after a few minutes of driving. If you're running a big cam, a higher idle speed may be necessary.

You'll want to use a non-petroleum based lubricant, like silicone spray, and a good amount of patience. And aftermarket cold air would make it much easier. With that said, this throttle body is not recommended for use on the stock intake manifold. It is best suited for engines with aftermarket heads/cam/intake/exhaust.

Ok so installed the TB and everything is awesome but I have an occasional high idle due to the throttle spring not being strong enough to close up also my tranny is shifting at wrong times due to this slop in the throttle? Stock TB didn't have this issue? Do I need shorter cables? Or is there an adjustment to make the TB spring stronger at closing?

There is an adjustment screw on the throttle body which you can back out to allow the "valve" to close completely. This is the setting that was set at the manufacturer.There is really no adjustment other than that. Is the throttle cable in good condition? Call our customer service dept. and we can get this taken care of for you. We can send you a new TB if need be. 254-296-6500

If you're referring to the studs that hold the throttle body and spacer to the upper intake manifold, then no it doesn't. Mine were in pretty bad shape too but took them to the wire wheel and cleaned em up perfectly.

Yes this throttle body and EGR spacer will fit the Edelbrock performer rpm II intake. Edelbrock actually recommends a 70 mm throttle body to be used, anything larger will require machining the intake.
