i have run tunnel rams on my sbf along time and still feel they will hold their own if everything is matched to them[ timing/ carbs/ rear gear ratio/headers/] plus--THAY ARE GREAT LOOKING --the only thing better looking are 8 injector stacks or a sweet liitle 6-71 BLOWER[ NOT UNLESS YOU HAVE TWIN TURBOS STICKING PARTWAY THRU THE HOOD!!!]
