I bought a used 360 from a friend. It's out of a 78 van and he rebuilt it mostly stock ex. for the valve train and ported heads. The weird part is that he used a cran hyd. cam with .454-.480 lift and 216 duration @.050 and 228 ex. with a comp. solid lifter and adj. pushrods. I want to know, since he only had it running long enough to break it in, if I will have oiling problem's or what valve springs to use? He used stock spring's and they don't seem to bind but really why use them if you know you can get better ones for the same price? I can get a comp. spring fairly cheap. I think a #901 or something. Would that be good? And if you have any idea what this thing should put out or rev too let me know. I forgot to say it has a weian action plus intake and a 750 edelbrock carb along with header's too.
those #901 springs are perfect. the cam isn't too radical, and the lift isn't over .500 the next step up is daul springs. but they are also close to double the price. those are #914. Go with the #901's. they're not too expensive, and will work alot better then the stockers, and will hold up to that cam just fine.
