at the moment i don't have a motor that has a tunnel ram on it but i have run motors with them in the past and have had no problems were you need to look at is the amount of cfm in total you intend to run if you run 2 450 cfm's that is only a total of 900 cfm and the motor should handle this combo but on the same not if you were to run a pair of 750's cfm now you have 1500cfm's and the chance of getting the motor to run smooth with that much cfm will be problem carbs there is a lot more you need to look at as over carbing is just one part the type of heads cam compression ratio ignition there is a lot to look at i do run a pair of 450 cfm on a cross ram on my 69 camaro and it runs great idles all day and is not bad on fuel for a motor that makes 525 hp on pump gas do your home work and all be fine
I bought 3 Holley 450s for my tunnel ram on my 396 never did get it right. I was ready to go back to my C396 7 3310-1 when I stumbled accross a pair of 600 model 1850-3. A couple of kits later it runs great. Now I have a pair of tunnel ram 9776 carbs collecting dust.
a friend of mine wanted the same thing so he took a wieand tunnel ram 2 Holley 600's he put the one carb on the rear as it is normally done, then he took the one for the front pulled the blades out of it and made a thin plate that looked like a gasket so that carb was a dummy he said it worked great.
