seems high to me from what you've said in your post. It depends on the specifics that you've left out. Without knowing, I wouldn't touch it. You've listed intake, heads, and some block info. What are you selling? Is it complete with tins, carb, crank, pistons, pulleys, accessories, everything? Is it a long block with an intake?
Are the cylinders stock bore size or overbored? Just saying there's no ridge wouldn't be enough for me. If you could check the taper when you're checking the bore that could raise the asking price if the bores are in really pristine condition.
I realize roller rockers are spendy, but I would want to know more about it before dropping so much. If it doesn't run, what's wrong with it? What was it being used in/for? What cam/lifters are in it (if you know)?
I'm not familiar with 4B heads. What's that? Is that an aftermarket thing? Are they closed chamber?
I've heard the offenhauser is not that good. I guess it's a decent street manifold.
That's all I can think of.
