bob i said they work. and i know i have a customers that run them .1 on a548 13 to 1 with 9377 holleys on it roller engine in a sand truck and drive it on weekends on the street dose it work yes is this thing bad ass you bet. would you drive it every day NO. now that is number 1. number 2 is a 55 tub chevy$70.000 truck with a 502 in it they drive this truck a lot . when his kids come home they try to brake it of him?. and i have had some to. i can not talk about any thing i have done with out getting in a pissying contest with some one on here .my stuff never had a dead spot in it and work very good for me and the tunnel ram were all long runners intakes and would idle all day just. fine did they need to be tune in ? yes they did. can it be done yes. would i do it again? you bet,. do they need work to get running yes. but if you think two fours are good for evey day then no one on here would build them or hot rods ?i am sure eveyone has a point of veiw .but all of them thay say it can not work or will not they may have never try it or spent the time to get it right. bob i did say it can be done if he want to try let him but i did say they need work to tune in and you will have to run a loose stall but a tunnel ram will make more hp over one carb. mine ran fine at 2500 rpm just fine do not over cfm the tunnel ram look at the ford truck long ram runners and some of the tpi intake they do look like tunnel rams dont they? yes the carbs will not work as good like the tpi but they will work if you want to spend the time .if not buy one carb and wonder what it would be like to have one. the fuel will pudle in a 2 4 manfold more than in a tunnel ran more runner and plenum will helps the fuel air mix there are some bad tunnel rams intakes that were junk from day one
