hello
I have bought a edelbrock 500 along with a jwr manifold. I need some help as at the back of the manifold there is a largish threaded hole ( roughly around 14mm). What is it for or what goes in it ?.
I have ran engine with this uncovered and it barely runs but when i cover the hole it runs allot better. I do still need to get it properly tuned and timed. I presume it runs better because its not drawing air through it.
It is a old 3.5v8 that is in my old sereis 3
any help would be appreciated
thanks
