If you are installing #96 heads on a 455, it will have enough compression to easily manage 224/234/112 sized cams and delivery a smooth idle, great street manners, and broad power curve.
If it's a budget build, get a Summit 2802 cam. It'll make good power to near 5000rpm's, and be pretty user friendly on currently available pump fuel as well.
I have two carb customers in the files who bought engines with around 9.5 to 1 compression with the XE262 cam in them, that absolutely HATE them at every level. I have another customer who opted for the XE268 cam and ended up with a "turd" for 455 street/strip engine. His car should be running high 11's/low 12's, and he's BARELY in the 12's with it in good air.
The owners of 455's with the XE262 cams both claim the idle is "quirky", extremely octane sensitive, and piss-poor power production at every level. One of the engines was "professionally" built by a shop who caters to Pontiac engines, where they were promised strong power to 5500rpm's and great street manners. The owner of that engine is about ready to take a long drive on a short pier with his pride and joy!.....Cliff
