Obviously written for ricers, but still good information.

Now, if he would just check the spelling of "gasses". I know it's an accepted alternative spelling but it just doen't look right. :W

bits of useful info, keep in mind the compression ratio, cam timing,engine displacement, intended rpm range, gearing and the intake runner cross section and length along with valve sizes and port flow rates all effect the ideal header design, and both the primair length and dia. should complement the collector lenght and dia. to maximize the results/cylinder scavaging
