Hey i was just wandering what weight of oil I should use in my engine. I am just getting done with Trickflow heads, cam, intake, rockers, 24 lb injectors, 70 mm throttle body, headers, cold air intake, mass air flow sensor, underdrive pullies, I was just wandering what gear oil i should use, I do drive it in the winter so it needs to be rated for cold conditions. I am also wanting to go with royal purple. Thanks.
