Who's running a 1904 Holley on their I6?

Yeah, my 250 has one. It is very simple. I'm not sure about fitting a 200...

 

I've had problems with the accelerator pumps on them, but i think it was because all the ones I had were too old an worn out

Here's what they look like

 

I ran a Carter YF on my 250 for a short period of time without any hood clearance problems. The RBS is a much, much better carb IMO though.

 

I had one on my '73 for a little while, too, but my air cleaner was hitting my hood a little bit. Its probably all in the right air cleaner.
