Thanks for all the suggestions.

I've read most of Vizard's books, and his BMC A-series book was the first engine-technical book I ever read...a real classic!
But Streetwize is right...I believe his cam formula (for LSA/overlap) assumes a decent exhaust and the Jensen is severely limited in that area. The BEST I will be able to do is some heavily modified block huggers (because even they don't fit without modifying to avoid frame rails and steering linkage...hell the stock cast iron pieces BARELY fit) and a 2.5" exhaust.

I was also already considering a single pattern cam. I just had no idea (being a stroker) what sort of duration I should be going for. It looks like Streetwize's recommendation of mid 230s is based on experience, so that is exactly what I was looking for.
