The best Street/Power cam I have ever used in mild 455 is an Ultradyne from Bullet Cams. .499 lift both Valves and 226 In 233 Ex at .050 on a 110 C/L.

I have heard of some unhappy experiences recently with Mondello .

Just my .02

Danny, is correect. The cam the he is mentioning sounds great. MW31 cam is a w31 camshaft that is somewhat lazy and outdated. That is a great cam for a restoration.

For your combo I'd do an Erson TQ50, 228/235 on a 110, .504 lift on both.
Cam, lifters, and chain set to your door is $295.00.

This cam would pull hard and I guarantee you you will hear it.

Thanks
