I have made up some long tube headers for my project. It is a very tight fit but it has come up great.
I have 1 3/4" primarys, into a 2 3/4" colector 3" long then will be into hiflow cats and throu a 2 1/2 inch free flowing full twin exaust.
I have got a cam, push rods and double valve springs from XR7 Dave wich are good for 6000rpm so i would like to tune it for around the 4500-5000 rpm. The heads have been ported to aid with good exaust flow but i am still running standard valves for now.
What I need to know it how long do the primary tubes need to be??????
If any one can help it would be apreciated, Thanks
