On my 78 Salon, I'm swapping out my flare fitting 605 box and power steering pump to 86 Monte Carlo SS fast ratio box and a reman O ring power steering pump also for 86 SS Monte. I noticed the Monte power steering pump pulley is larger diameter than the Salons. I'm planning on using the smaller diameter Salon pulley because I don't want to have to buy new longer belts. Is it going to make a difference on pulley diameter size? A smaller one will have it spinning faster. Is this going to be an issue?
