Holley 58mm TPI Throttle Body 112-503

So I bought this from a board member a few months ago. Had a good price on it, got excited and didn't check the part number. Thought it was the later year model with the different linkage. This is earlier style. Part number 112-503. Part is practically brand new. 9.9 out of 10. Hardly any miles. Have the box, plastic bag and everything. They sell new for $475. I'll fight the low hanging fruit urge to sell and make a profit, and will offer it up for what I paid. $275 plus shipping. Won't go lower, as it's all but new at almost half price.

Why don't you just change your throttle cable?

I actually did. Well...I have the Lokar cable so you can swap/adjust ends. Anyhow, I did, and I quickly dialed in idle and it ran great. I just didn't like the non progressive linkage. I suppose it's all what you're used to, but I didn't like it.
