I am putting a Weiand Tunnel on my 454 and two Holley 660's.
I don't have the tunnel (at least not where I can get to it right now) to look at.
I want to mount the carbs sideways. Do I have to have an adapter? I want to go ahead and order what I need so when I get my boat back from paint (it is in Houston and I am in Dallas), I will have everything I need to get it in the water without having to wait on ordering stuff.
Also, what is a good GPS Speedometer? Any that I need to stay away from?
Thanks.....
