i have heard a lot of opinions that bigger is better. i would agree in most cases, but I am not building a big inch beast that requires the increase in oil flow. I am rebuilding a stock evo just to get back on the road and to last for a while. Some tell me to use stock HD lifters with S&S oil pump. My pocket book is hurting a little after an engine over haul. I am leaning more towards Crane lifters with maybe a sifton oil pump. A few have told me Not to use a sifton oil pump as quality has changed. Is this true Can anyone give me some feed back on Sifton oil pumps. What about Revtec. Do they have good pump & lifter set ups for a stock EVO?
