Re: 454 Camshaft Choice? Decisions Decisions!
There's not really any simple way to explain camshaft dynamics or any real way to compare
I'm not sure if you got rid of that cast iron intake yet but that right thee is killing as much power as a cam swap would facilitate
For cams there are two different durations that you typically see, adv duration and adv duration at .050 lift. The later is used industry wide (almost) to compare camshafts. Lift is simply that lobe lift and lift at the valve.
There are extensive online articles that go into detail and explain everything much better and since I don't feel up to the task of typing two pages (yes two pages) I will leave it up to you and google.
That said what your looking for is an RV style cam. Like a comp 260. You can also call individual cam company's and they will spec a camshaft for you based off what you want and what your setup is. This is the more recommended route since you will always be sure you got the best matched cam for your needs. My recommendations bullitt cams, isky cams, crane cams, lunati cams, Howard's cams and last but least comp cams. In that order.
You will also likely need matching valve springs and new pushrods and long slot rockers depending on the lift. A lot of people run stock valve springs and do just fine but I don't like 30+ year old worn valve springs on any engine.
