Does anyone have the diameter of the pullies for the 350 A/C and non-A/C versions for the crank and water pump? Also the depth (front-to-back)? Do you know if they will fit the 455? TIA.
350 crank pulley has a diameter of about 6 5/8 and depth of about 3 1/2". It will directly replace the larger diameter 455 pulley.
so, just out of curiosity, if you put a 455 crank pulley on a 350, would it make for any noticable increase in cooling or alt output?
If you go from a 350 non-A/C crank pulley to either an A/C or non-A/C 455 pulley, you will speed up the water pump, fan, alternator, etc. The 350 A/C crank pulley is slightly larger so only the 455 A/C pulley is larger.
:Smarty: note: if you get a pully off of a 69 or older engine it will be of diffrent length. (the water pumps are diffrent lengths) also 70 is a mixed year so some 70 pullys are diffrent than others on the 350's just to warn ya. Nate
