torn between engines

[krazy_texan]

ok here is my dilemma, my truck has an inline 6 which runs great for the most part, it leaks a little oil and after driving at high speeds after coming to a stop it takes a litte bit for the oil pump to catch up so i have to sit at traffic lights with my foot on the throttle just a little bit. this thing starts up for me every day rain or shine. It is a tried and true straight six. Now i also have a 350 bored .30 over sitting in the shed just dieing to be built and intentions where to put it in my 65 and have a nice ground pounding daily driver when all said and done. But now i cant make up my mind cause this old inline is really starting to grow on me. What do you guys think should i keep the inline and proceed on with other plans for the truck and put the 350 in another project or should i should i build the 350 and drop it in. Lets here it guys.
