My dad bought an Edelbrock intake for $5 at a yard sale. Its from a chevy 350. I couldn't find it in the Edelbrock magazine I have, probably b/c its too old. The only numbers or anything it has on it is C 4 B. I hope somebody can help me with this.
Is it a single or dual plane manifold? If it is a single plane is the carb. flange twisted or straight? I remember seeing some old single plane edelbrock intakes that are not in any new catalogs, they were called torkers or tarantulas.
Maybe it's a ST-2P manifold, that is the edelbrock dual plane manifold my dad put on his 69 vette 20-something years ago. If it's a ST-2P it should say right on top of one of the intake runners. This intake was sort of the pre-performer manifold and was good from idle-4500rpms.
Ok, thanks guys, so now the question is "would this be better than my stock manifold?" My stock manifold has 98k miles on it, this one doesn't have as many, not sure how many though, and the divider to make it dual plane was shaved down some, so its sort of single plane.
