[800hp]

fastrods with using a flat screen with round holes like that you don't have enough air flow. i used a diamond pattern then made a die so i could press it into a 1/2 round convex shape that worked very well on the flowbench. these were on a 395 ci. smallblock that made a little over 800 hp. i am going to make some for my twm here in the next week ore two if there is any interest let me know. jim
