Now its question time.........
Been looking and fitting stuff tonight, and have to ask,
1, with new alloy pulleys, is it normal for them not to lign up without shimming various items to make them lign up ? Alternator looks way off now - about half the thickness of the belt.
2, Got a replacement Rochester and am wondering what the large connection is for at thr rear centre - low down, I know its not the PCV as thats at the front ??
3, Choke heat riser pipe does not seem to have anything to connect to on the new Performer manifold......... ??
4, But there is a sort of triangular casting rearwards of the carb on the passenger side of the new Performer, with a big hole in it and looks like the ability to take 3 bolts to hold something attached - any ideas ??
What is it for.. ??

1) New alloys? What is new that's causing belt mis-alignment?
2) That goes to the brake booster,..there's a brass fitting (or plug if pwr brakes aren't optioned) then a flaired-end 8" long tube and then the rubber hose to the booster.
3) I think the performer accepts the divorced type of choke that has the thermal spring, housing and rod. I don't think there's an easy way to make the later style chokes work, though I've nver tried.
4) Don't know...

In a separate thread ... you indicated you have new alloy water pump. If so, that may be the root cause. True vette pumps have discrete dimension from hub face to block ... it may be a short pump ... but it must be a short " vette" pump in order to align w/ vette pulleys & brackets. All short pumps are not equal dimension ... vette pump is slightly different ... this is OFTEN the root cause of quandry many (like you) have found themselves facing.

The typical mismatch requires shimming between water pump hub & water pump pulley ... IIRC, about 3/16". Lotsa kits out there just for this that contain several shims in both 1/16" & 1/8" shims in same kit. Moroso, Speedway etc. If ... IF ... your problem is what it appears to me ... ONLY water pump pulley requires shimming.
-edit- Trust me ... do NOT shim between wp hub-pulley w/ a handfull of washers ... over time, the water pump pulley will probably end up cracking. Do use the correct shims that are about same diameter as wp hub.

6mm ain't that much different from 3/16" ... I looked at some pics of yours in another thread ... bet dollars to donuts you need to shim between hub & pulley. Washers will be OK SHORT TERM ... but get the correct shims.

Update - pulleys looking good now. No need to shim, when all pulled up they align pretty well, only one thats a bit off is the original power steering pump as it mounts to the engine - nothing to do with the new stuff.
So, on to hooking up other stuff today - if I can find all the bits in my garage.
