Help with BB pulley system

Can anyone explain to me why the short water pump v groove crank pulley and water pump pulley are available with all v groves being equal diameter and the long water pump pulleys are staggered diameter? I like the equal diameter look and want to keep it. I cant understand the spacing of the pumps from the block need to change the pulley ratio. I am converting to P/S on my BB and need to move my alternator to the Pass side and go long water pump. Cant fit P/S under alternator on drivers side. If money wasnt an issue I'd buy the March setup. Thanks

Re: Help with BB pulley system

Pulley diameters varied with options. Crankshaft and water pump pulley diameters were different between A/C and non A/C cars. A/C cars had larger diameter crank shaft pulleys and smaller diameter water pump pulleys to spin the water pump faster in order to promote better cooling. Non A/C cars had a smaller diameter crank shaft pulley and a larger diameter water pump pulley. You could mix and match pulleys if you choose to promote a more uniform look, but it is difficult to say what effect if any, it will have on cooling.

The aftermarket offers many different pulleys. Make sure you go with the "Big Block with Long water pump". You may have to go with Non-stock length belts etc. Summit has many different pulleys.

Re: Help with BB pulley system

Thanks guys..it seems like nothing I ever do on my car is easy. I want to put power steering on my BB Camaro. Currently it has a short water pump, 3 v groove crank pulley and 2 grove water pump pullet. Everyone said that I have to move the alternator from the drivers side to the passenger side and go with a long water pump. Well I just got off the phone with my buddy (who moved to Florida) and told me his 68 454 short water pump has the alternator and p/s pump on the same side no problem. He cant be sure what bracket he used to mount the ps pump. It may have been his old 68 Camaro small block brackets. Another call to summit and they told me that I couldn't have ith pump and the alt on the drivers side. If my buddy did it, and I have pictures, what gives? Does anyone have any experience with this? I'll try to post pics if needed. Thanks!

Re: Help with BB pulley system

67 and 68 Camaro's had the alternator AND the power steering pump mounted on the driver's side of the engine for both small block and big block. Both applications used short water pumps. You DO NOT need to swap over to a long water pump set up to install power steering in your car. The brackets that you need to mount the power steering pump are available from any of the parts places out there.

Re: Help with BB pulley system

Heres his 68 BB short water pump with both alt and ps on the drivers side. This is what I would rather do. Does anyone know what ps bracket to use for this setup?

Re: Help with BB pulley system

Matt...thanks for the info. I was incorrectly informed by many. So if I buy a BB SWP power steering bracket it should line up? Summit told me no...

Re: Help with BB pulley system

You need stock power steering brackets for a 67-68 Camaro with a big block. They are available as reproductions. Eckler's, Classic Industry's, Camaro Central, Heart Beat City, all sell the brackets that you need for your install.

Re: Help with BB pulley system

Thanks guys! Just got off the phone with Summit tech. I can use the factory type ps bracket but my billet alternator bracket below has gotta go cause the cap of the can wont clear it. Oh well I can live with that. Thanks for the help!

Re: Help with BB pulley system

Thanks again guys..I received my parts needed to mount on the drivers side and all worked out. I didn't have to change out my billet alternator brackets either, which makes me happy. Now I need to return brackets, pumps and pulleys that I wont need. Thanks again

Re: Help with BB pulley system

The C3 Corvette used a short water pump for a number of years after 1969 (can't remember when the C4 came out) when the rest of the fleet switched over to the long style. You could use the deep V pulleys and brackets for the 1965 and up to 1974 Corvette (last year for the BBC in any car) as a source of parts. They are offered as reproduction parts.
