Ok, can SBC heads be put on the wrong side? Put these on in the middle of the night and when I went to put on Alt. realized I had no bolt holes. Facing the motor, there are holes(3) on the right head and only one on the left. I thought I could do this. Next, If heads are ok, what size belt do I need to just run the waterpump. I'm willing to try it with no alt & powersteering. Thanks in advance! Race

no, not if they are a set. one bolt hole on
passenger side should be all you need to mount the alt. I use 3 bolts to mount mine,
one in the head, one in water pump, one in
intake manifold.

For belt size, get a piece of rope or string,
lay it out on pullies like it was a belt and measure the string length, do this with pullies in the proper position.

you don'rt need an alternator anyway just get your power steering bolted up and i take old belts and cut then to fit then take off 1/4 in to make them tight take it to the parts store and tell them you need a belt this long the way i do it i have one belt that runs from my water pump pully to the pwoer steering pump and one that just rund the water pump if you get a power styeering pump off an old van you don't need any holes it mounts to the block and exasut manifold

Read some of the other post on power steering.
If you like not having busted thumbs and wrist, don't go without the power steering.
I'm having trouble getting mine right, (about ready to throw it against the wall)
but I want to race all season. So i'll keep trying to get it right.

FLANNDAD 17J is right,the older style pump works better,it uses the pivot mount on the water pump where the bolt goes all the way thru the mount and has a nut on the back side,the later ones are threadded for a bolt but usually don't line up as good,i loaned mine out and it worked good enuf that it didn't get returned!

Gave up on the Alt., still trying on the pump and will continue til I get it right. Does anyone have the part # for the belt that goes to the crank and waterpump only (stock pulleys). Was going to measure last nite but played with the kids instead. Thanks! Race

There are numerous stock pulley sizes and combinations to just look for a number. The best way is like racer17j described. Keep in mind that you'll never just slip the belt on by hand, it would be too loose. Put it in the lower pulley groove and try to jam it as far as possible on the upper pulley groove until it's about halfway on and stuck. If you did it in the direction of the engine rotation, bumping the starter once or twice will mount it. Check the tension and you're set. One helpful tip if it's being tough is to loosen the water pump a bit until the belt is on then tighten the pump. One more thing, don't get a belt that is just plain too small.

I bought a real nice set of aluminum pulleys at an auction I was very proud of them untill I couldnt find a belt that fit right and I wound up putting one on a half in. to short I rolled it on. The first time on the track the shaft came out of the water pump and the fan went thru a new Aluminum radiator so to make a long story short get the belt size right even if you have to change pulleys....towman
