How much do you think I could get out of these?

How much do you think I could get out of a new single 4v Weiand tunnel ram for a 289-302? It's in great condition and is barely a year old and not driven much in that year. I paid about $250 for it. I would also include a Mr. Gasket street scoop with butterflys which is also in good condition. How much do you think I could get out of this package? Thanks.

Yes I'm thinking of selling it. The more I drive it, the more I come to realize how hard it is to keep it tuned properly and to run smooth. It just won't run smooth. It sputters at WOT, the idle surges and changes, and everything. At first I really didn't care, but now I am getting irritated since it just won't cooperate. lol

I am also starting to feel that it looks very tacky and cheesy.
So I would like to sell it to someone who can get some real use out of it...

I would like to get a Weiand Stealth intake and put a cowl hood on.

Anyone know a price?
