Full Race was for racing only. The thing is that each cam grinder had his own version of a Full Race Cam. #/4 was of course 3/4 the intensity of the Full Rcae. and one not mentioned now days at all was the 1/4 cam. That was wilder than stock and was great for mild street cars, while the 3/4 Race was used in the baddest street cars.
I am suggeting the original poster with the 396 get him a good hydraulic cam that is best for his engine and his car instead of looking for the radical lope. If a rad lope is what you are after, the 305 H is very rad. With that engine if you do install a 305 H it will lope bad but anyone with a bone stock 396 will blow your doors off.
You have what could potentially be a good driving combination and even possibly use 87 or at least 89 octane gasolene with what yoou have mentioned. Don't blow that with a radical cam. Remember that the same mild cam in a 454 will be wilder in a 396. Also know that you already have low compression and the more radical and more overlap the cam has, the effects of a lower compression engine at lower rpms will be that of even lower compression.
Frankly a bad radical idling cam in a low compression engine sounds to anyone who knows engines like a turd. It will be. A bad idling cam in a higher compression engine is what is the turn on. You can still get a little rump and keep your power if you don't go crazy.
