Here's some good info.

I have always run Crane Cams.

You want to stay somewhere in the range of the chart on page 19.

Roller cam. Buy once, cry once. You'll make up for it in the price of oil. Non-roller and you'll be buying VR1 or a zinc additive.

I used a Melling MTC-1 cam in my 350, good low end torque and driveability plus it sounds pretty good- no issues with oil but I do run Amsoil Z-Rod made for flat tappet engines.

Bringing this thread back for a quick question guys...

What does it take to swap Vortec heads onto a 350? (1980 engine to be exact). I have the Edelbrock intake with the canted canted bolts (from a previous TBI to Carb swap), are any other modifications required? Assuming all coolant passages are the same? I know roller cams are nice, but the flat-tappet rockers will bolt to these as well, correct?

Since the start of this thread, had an engine rebuilt, ran it since Nov of last year, #3cyl was buring coolant, turns out the head is cracked, found a set of good Vortec heads for $150 that are cleaned up and ready to go. Would like to swap them on...
