Well, it's not entirely awful, but still mismatched. I'd expect idle to be terrible and very little vacuum. I've run that level of cam in a small block with about 9.5:1 compression and it was a real fun build but took a lot of work to get an acceptable idle, especially with A/C and power brakes.
How certain is he about the 8.7:1? A lot of the stock replacement stuff ends up lower compression than advertised. Replacement pistons sit further down in the hole than OE, head gaskets are thicker now than they used to be, etc.

I realize this is an old thread, but just wanted to share my experience with this cam if this subject is still of interest to anyone.
I have a 1974 Delta 88 convertible with 350 engine I had rebuilt several years ago, approx 9-1 compression with aftermarket
pistons, cylinder head milling, and an adjustable valve train. I chose this cam because of great results I had with the similar
Voodoo 262/268 cam for my mildly built 9-1 383 1970 Corvette. The Olds now has almost stock level vacuum and idle is set
about 725 RPM. Idle is noticeable, but definitely not crazy. I later ditched my troublesome Quadrajet for a Holley Sniper fuel
injection system with timing control, made possible by easily modifying a computer controlled HEI distributor from a 1985 307
Olds engine. Lunati's recommendation was their cam one step smaller, considering weight of this car, but I have zero regrets
for choosing the 262/268. Has great power and torque off idle to at least 5500 RPM. This big boat really takes off when you
kick it down in passing gear, fortunately Olds used the 3.08 axle this year. Perhaps a less modified engine would be better off
with the smaller Voodoo cam, but this one sure works great with my combination.

Out of curiosity - Many years ago I built a 455 with L2323F pistons and that cam (Voodoo 262/268). I didn't surface the block or heads. Used an off-the shelf head gasket (0.040"ish), so compression is likely in the low 9s if I'm lucky. Cranking compression is 150PSI across the board. Does this sound reasonable for this cam?
Thanks.
Thanks.
