the idler pulley you bought is not going to work correctly, because it is to large in diameter (90mm). you need to buy a second belt tensioner to rob the pulley (75mm) from. you need to put a .025"-.030" shim between the pulley and the belt tensioner and the idler pulley and the timing cover. gates makes a 112.4" long 8 rib belt.
Chico> I just wanted to make sure I was straight on all the info. that I gathered from your posts. You used your factory 6 rib tensioner? Did you change the pulley on the tensioner to the 8 rib from the Lightning? Also> you changed to the high speed idler pulley? Thats the only two things that I will have to get other than FORD?
thanks for any help!
Harold! The only aftermarket item is the idler pulley made to fit the 8 rib with high rpm bearings...gringing on the alternator and the blower bracket..
Just a little info! Crash eliminated the Auto. Transs and installed a 6 speed..said he was tired of getting beat by lesser cars on the street..He has a new motor pulling about 35 more rwhp than before..but has not hooked up the no2....
Chico> right on man. Thanks for the info! I heard that about crash> I read over at nor-cal almost every day> he got tired of the auto and now is almost about to sell his car> soo many things he said were making him upset> Ive been there> its a bad place to be> but thats what we get ourselves into modifying a car like we do

Brian Bradford> sorry for taking over your thread> I will reply next with pm.
Thanks for posting the great info! I am going to order these parts tomm. but am unsure about what you did with the tensioners? It looks like you have the stock tensioner in the picture> but you also have the manual tensioner> are you going to use both? Or is the original tensioner just so that you can take the pulley from it?
Thanks for any help!
