the throttle bodies are 50mm. Not sure on brand.

It comes with the following
1 intake manifold to suit 5.0l / 302 windsor
8 throttle bodies
8 ram tubes
2 fuel rails
1 throttle cable center linkage
I have this set up on a completely stock 5.0l. I am using a Microtech lt16 ecu, msd 6al and a mallory dual sync dissy. motor runs really well and sounds awesome at revs.
The reason why i chose Microtech was the fact they set the ecu up with the desired crank sensor at the factory and then send you a package you install and starts up easy.
