On certain 427's and 454's they have the same setup as mine with the belt only going from the crank to the water pump.
They use GM #3952336 belt. That belt is too small for my application.

How do you install a belt on a mid 70's that only goes from the crank to the water pump? They don't move.
Assy manual DOES show a single belt from crank to w/p pulley. Never seen one set up like this. The only way to change it would be to remove the fan and pulley. I have to assume it was an "emergency" type deal in case the alt belt broke/failed. Ignore the smog pump in the drawing...the legend calls out "belt w/pump (exc C60 or N41).

Yes, that to replace the belt you need to remove the pulley, install the belt on the pulley and reinstall both to the engine together. The assembly book for 1974 shows it that way on a vin "y" (454) motor. I may be dating myself but many vehicles had a set up like this in my youth. I have tried all the regular providers and found a gap for the 1974 year belts so I went online and found a place, VBelt Supply.com. They have many different size belts listed, I ordered 6 different belts from them and I'll see if any of them will fit. Check them out their prices are not bad.
Thanks for the replies,
Greg
The pic above is directly from the '74 Assembly Instruction Manual, for L48 and L82 engines. THE OE part # is 3935420, which is still available from several sources.
PARAGON CORVETTE shows it for $28. Quanta Products has correct part #, dated belt for $26, if you are going for Judging points.

For whatever reason, I didn't see that page. I'll blame it on senility.
It looks like the right size.
Thank's,

So....Now for my question. Were L-82s Big Blocks or just small blocks? It was my understanding that Big Blocks had a different identifier.
The L82 took the place of the LT1 as the "high performance" small block starting in '73. It is a small block 350.

That was my understanding. So....What am I missing with the 427 and 454 in the equation? Did the BBC, and SBC have the same set up? Why is this so new to many of us.

Not really sure what it is you're asking, Mark. If you're asking about belt set-ups, then no, the small block have different belt/accessory setups from big blocks. Even small blocks have different set-ups depending on equipment/options.
