Opinions on the Holley Carb for 258

I posted in the CJ forum, but didnt get the info I needed. I have a 78 CJ7 All stock. I hate the Carter 1bbl. I am looking at getting a Holley 2bbl. They also offer a 1bbl. what do you think would be a better choice. these are both around the $150 range. and thats what I hear the MC2100 is going for. So I just need some opinions on this Carb, thanx.

Thanks, I talked to a buddy of mine, and said that Holley is really hard to tune. you just confirmed it for me.

The MC2100 comes in a few different sizes. If you didn't know the size is shown on a stamp behind the throttle linkage which stands for the venturi size of the carb. The 1.08 stamp is what you want for a 304 or 258. I just ordered one for my 258 (I told the parts co I wanted the one for the 304) and got the wrong "size," they sent me the 1.21 MC2100 (which I returned.) If you get one, just make sure your getting the 1.08.
