I have the 440 Source RB 4.35x4.375 kit (520 ci) and ported TF 240s. (360ish cfms)
I used this Howards cam
https://howardscams.com/i-24079924-howar...lifter-kit.htmlThe cam works really nice for me installed in at 102 degrees, also used their EDM lifters.
It pulls about 8.5 inches of vacuum.
I have a 4 speed and manual brakes, cam might be a bit much for power brakes but it pulls well.
PS the effort to clearance the oil pickup boss was really minimal, like literally a minute with a die grinder.
Here;s a video of the cam installed in at 104 degrees, the extra 2 degrees of advance really cleaned it up down low.
