I got a set of injectors from Cotton's in '01 all the invoice says is "40lb injectors". I looked at them tonight they have the # 621037 on them and a lime green top. I also have a set of 36# Ford blue tops. Wich ones are better for a street driven car? TE-44...stock stall...dutt neck ic...3" THDP....probably Champion Irons to replace damaged stock heads...(Will upgrade injectors later but for now...??
