I wanted to know if anyone knew a few sites besides howell that had some of these parts, preferably the cheapest. I need a high volume melling oil pump, a carter water pump, and a manual tensioner kit. Is the carter water pump an improvement or would any water pump be pretty much identical. Would The manual tensioner help out, as I see a lot of conversions or is the hydraulic tensioner good enough for a high hp turbo set up. And lastly anyone know a competent engine builder for a precision build of the 420a with a stroker kit, in PA or surrounding area. I am in central pA in state college. Thanks in advance for all the help.
