Reason for asking - the carbed version's have a high rise GM intake. The MPI's have fuel injection, and yes, if you convert to carb with Holley 800 or so and a good aftermarket high dual plane you will gain power. With it's dinky lame azz cam, a HR dual plane with work well.

Don't forget about the tunnel ram guys. The old myths about them have been smashed time and time again and a properly tuned tunnel ram will increase the air flow of the cylinder head...

The only time I have flowed an intake and recored a increase in the flow of a cylinder head is with a realy well designed sheet metal intake, most still loose a bit. A well ported cast intake of any type or out of the box drops aiir flow through the head.

No it does I've seen it done on a flow bench. It's been a couple years since I've seen it and honestly at that time I really wasn't interested in it @ .500+ lift the head started gaining with the tunnel ram on it not much but it started gaining. I kinda dismissed what I witnessed on my buddies bench until about a year ago. I started looking into tunnel rams. I called all kinds of cylinder head guys alot of them said yes if done right the will pick up some said no they will not. They are called a tunnel ram for a reason...
