236/242 112 is a little on the large side for a 350.
Even with ported heads and a decent valvetrain.
Will it fit? yes.
Will it work? yes.
Is it optimal? Not really. It makes good peak HP numbers, but lacks low/midrange TQ.
Something closer to 228/234 would net you better overall performance.
Those lobes (2.77ish ramp) are also a little less aggressive than what I'd like to see in a performance cam (3.10ish).

CC 236/242 .555/.576 on a 112
Same cam. Works great. Sounds good. It is on the big side for a stock 350ci. With my terrible tune/mechanical problem though it put down the torque from 2000rpm all the way to 6200.
