Simple Man, I am not trying to hijack your thread either but this info might be of use.
Sisqocracker, I use a small block instead of the newer LS blocks for several reasons, the shape of the bellhousing, the price, the lack of computer problems (especially when connecting it to a non-computerized and probably foreign transmission), and others. One other reason is the accessory drive belt assembly. When a serpentine system starts rearranging things, it is not easy to do, especially with the idler pulley(s), it is expensive, and it is limited. Also the water pump is a nuisance as you stated. With a small block, I can I can start with the old style but readily available short (5-3/4") water pump, which allows me to move the rear bulkhead back and gain critical inches of legroom, then choose any combination of readily available brackets and v-belt pulleys. Even if I cannot find the right bracket, ones for the small block are easy to fabricate, and no idler pulley to deal with. I find it a much simpler and much more economic solution.
