Cheepy Three-Sixty build
I don't understand the squabbling, the port clean up is what many here will do and the flow numbers only show an improvement that justifies the time spent.
If this was a high end performance build for the track then more time and bigger numbers would be expected, but not a little 400hp street engine.
Really like the idea of using inexpensive Chevrolet or quality OEM over the counter parts. I greatly appreciate you documenting this build with all it's twists and turns, and will definitely help someone save a headache and money. Thanks, Ramm.
