Comp Cams has a free computer program that you can download to help you pick your cam. You put in everything about your engine, car weight, intended use, and it will give you serveral options with all the specs, and if special springs etc. are required. Most people over cam their engine and don't normally run in the RPM range the cam was intended for.

Brent,
The datasheet of the Edelbrock Performer Heads says: Maximum valve lift is .575". A lift of .574" is very close to this max. No more no less. It made me wonder if that will become a problem in the long run.
The sheet also mentions that the max rpm for these heads is 5500 rpm. That seems a little low to me (thought it would be 6000 rpm), but it is what the sheet says.

Nice to know this cam will fit my engine! Thanks for letting me know.
I wonder what in practice the difference is between a XE284HR and a XE274H.

Have a nice day!
