Anybody feel like clearing this up? Which cam and lifters?

1.88's can easily support 400+ hp. Depends on the port/VJ in front of the valve head. Look at the EQ and rhs heads with 1.92 valves, they don't appear to have much issue getting over the 400hp hump.

The how to hot rod SB is a good book for general information. Some of the info, stock SB's blocks are only good to 400 or 450 hp... not so good.

Most cam companies will ask you some questions, if you are lucky, then go straight to the catalog to find a shelf cam to run. Sometimes there's nothing wrong with that, other times it's not a best choice. Another fun one, call the same cam company and talk with three different people, get three different grind suggestions.

Talk to an engine builder, lots of times they can get you a camshaft from the same companies for same and sometimes less money than from summit shelf stuff. Just depends. Ask Brian from IMM, Mike at MRL, JRob or any of the others that regularly build stuff and have manufacture access, they can get you a suggestion.
