So the GN crank pulley bolts on fine?
See! Thanks for the pics Texasturbo - I don't have any good ones immediately available of my setup when I had my 455 so this is great. Yes everything bolts up fine. Need to make a couple of small brackets as mentioned and use spacers or stacked washers in a couple of spots around the alternator. Appears WP works as I recalled. Best part to is it leaves the entire passenger side empty so you can use it for a turbo/supercharger setup if that is in your cards OR as I did I mounted my coil and a couple of other small items on a bracket I had made that bolted to the passenger side head.
Additionally, I note you have an AC compressor on your setup - just FYI for those that don't have AC the AC delete for the GN setup works too.
Doing the same.
Looking forward to how it turns out. I have the same chevy accessory set I want to use on the 455 I have. Looks good.
All done. Belt I got from my brothers specs was to long. Ordering 100 inch belt.
Bracket drivers side for alt and ps pump
Bracket passenger side for AC pump
10118751 - cut off bottom support.
Aluminum plates attached to head's are 3/4 inch thick. Drill and use beveled head grade 8 cap screws. When drilling for mounting brackets, use fine thread and tap all the way through. The thickness and fine threads will prevent failure.
Ford water pump pulley with . 25 inch spacer or flat and lock washer as spacer behind pulley.
1 inch to 1 1/8 aluminum spacer made with 3 counter sink indents for mounting to dampener. The remaining 3 are used to attach Chevy pulley.
The Chevy pulley holes will need bushings if using the same size for the factory mount. Otherwise, you can use a shouldered bolt.
All mounting bolts I used were American. I drilled the bracket mounting holes to close tolerance of the bolt shoulders.
The hard part. The distance from the back plane of the left bracket to the front of any pully is 5.7 inchs. Build your idler pulley mount as you see fit or by material. Take into account the height of the idler pulley and centering washer.
I'm ordering a Gates belt k061000 instead of k061031. That is a 3 inch shorter belt for my application.
Thank you for the list!
Looks like I need to go shorter belt. Ugh.
With 2 idlers and a tensioner/idler you have went to great effort for good belt engagement on the accessories themselves but it looks like you have almost zero engagement in the actual crank pulley. Does the PS pulley get belt engagement from 2 sides?
Ken, yes the ps has contact on both sides. I have hard contact from the 4 o'clock to the 9 o clock position of the crank pully. I'm thinking the amount of surface contact and the belt tension will suffice. I got the belt down to 98 inches, and extremely snug before tensioner.
Theres a company up in Minnesota called CVF. They make a kit for I believe $1800. All brackets and new accessories for the install. You'll need the longer nose water pump. I bought the flowkooler one for my install. This unit is amazing.
