Swapping 350/454 - alternator bracket?

I'm swapping out my old '77 350 with a 454 from an '86 suburban. The 454 has wide pulleys for a wide serpentine type belt on the crank, alternator, water pump and smog pump. AC and power steering run off a V-belt from the crank.(V groove pulley is behind the wide pulley on the crank)

I would like to use the wider belt and pulleys but I don't want to install the smog pump.

Question #1: Can I get a shorter belt to run the alternator & water pump?

The alternator and smog pump bracket is one large piece. I'm not installing a smog pump and was wondering if the brackets from an older, none serpentine type belt will work.

Question #2: Will the brackets from an older style alternator fit and align the belts?

Unknown as there was no option for with out air pump in 87, and the 7.4 wasnt available in 86. More than likely yes you can , but its going to be trial and eror to find the right one

No use the all in one bracket and leave the air pump off. Thats the way GM did it on many vehicles.

No, I doubt it. You might be able to shim it but......why not look at moving up the newer style alternator, they put out amperage, weigh a bit less, and over all just do a better job of running everything and keeping a battery charged.

You leave us to assume the vehicle recieving the engine is a 77, but it would be nice to know for sure. Also dont forget your going to need to replace the front springs, and if the ball joints have been around awhile I would replace them as well as the shocks. Lot more weight going to be on the nose.
