Hi all,
I've recently got a 455 for a remotoring project. It came without any pulleys or alt or PS pump. I'm trying to sort out which pulleys I need and, while there is lots of info out there, some of it is confusing to me and some of the pdf scans are too fuzzy to read.
I have a water pump with a 6" snout, so I'm assuming that determines everything else. I don't need AC, so alt on the R and PS on the left and 2 grooves on the crank pulley...correct?

Here's what ive gleaned from a post that showed a diagram for a 2 belt system, tho it appears that this might be for a shorter snout water pump so won't work for me. I'd sure appreciate someone getting the right numbers for me. Thanks, martinWater pump 405462, 405461 km

Someone wiser than I can tell you whether or not there are 2 groove pulleys for the 6" water pump, but considering the engine looks to have had a rattlecan rebuild maybe it's time to replace the waterpump anyways? Then you can get a waterpump to match pulleys and not be stuck where you're at now?

I went down the "what pump, what pulleys" rabbit hole in a thread a while ago. The answers there may be helpful if you change the water pump. https://classicoldsmobile.com/forums...dation-176258/
