I have a holley 4bl manifold for 20r id sell.. Holley -street dominator. Its pretty old with jap casting marks.
Yes. PB Blaster, EZ out, heat. I'm to the point where there isn't much material left to even work with.
I've thought about that route, but haven't tried it. I was really hoping to just pull this out or find a replacement.
You might try it, it would definitely be cheaper if it worked! Where at in washington are you located?
