Not sure if the same? ---------- Post added at 09:57 PM ---------- Previous post was at 09:53 PM ---------- Off George's site: Water pump - 1238156 balancer - 1235779
I don't have either of those. All of mine are for A/C or Stage 1 option which have 2 grooves on water pump pulley and 3 grooves on crank pulley.
Jeff, if you need one for a Stage-1 it would be the same as the AC. All Non AC Stage-1 cars used the AC pulleys. You need both to match. They end with part #s 776 and 777 I think.
Got my part numbers off George's site. Non stage, non air 1971 455 Skylark. Hopefully my numbers are correct.
Dave, I think he's looking for the two groove crank pulley and single groove water pump pulley since it's a 350 to 470 swap without AC in a 71.
OK, got it now. Here is the break down. All Stage-1 and GSX including all cars with heavy duty cooling used the AC pulleys even without AC. These were meant to be used with the long water pump. These pulleys are numbered 1235778 for water pump and 1235777 for crank pulley. The heavy duty cooling system also used the double alternator pulley even without AC. The base 455 with the flex fan and spacer and short water pump I think Jeff is using are the crank pulley he is being offered 1235779 for the crank and 1238156 for the water pump. This is directly from the assembly manual. Jeff does this match the numberst you have?
The 1235779 and 1238156 is what I thought I needed, I do not have a 1971 assembly manual to confirm. I planned on running a fan clutch not a flex fan, did your numbers above come from a 1971 assembly manual? Thanks for the clarification.
Jeff,I looked at mine finally,I have 2 feet of snow in my back yard,I don't have the # you are looking for.Bruno.
