I want a max effort cam that is good with carbs and nitrous. I plan to spray 100-200 through a plate kit.
I have a set of virgin 799 heads to replace the 706's. I can mill them if needed but I do not want to spring for full out porting and polishing.
So, with all that said. what cam/spring/pushrod package would you go with?
With your combo, I would run this camshaft: http://store.cammotion.com/hot-stree...reted-camshaft
It is 227/237 duration on a 111 degree lobe separation with 4 degrees of advance and .595" lift. With this camshaft, you could mill the heads up to .020" and still have good piston-to-valve clearance. It will also work good with up to a 200 shot of nitrous.
The next step up in aggressiveness is the Junkyard Dog: http://store.cammotion.com/junkyard-...plane-camshaft
It is 232/244 duration on a 111 degree lobe separation with 4 degrees of advance and .621" lift. With this camshaft I would not recommend milling any more than .010". This camshaft can handle a 200 or so shot, but may not be as quick on motor in your 5.3 as our Hot Street camshaft listed above.
For valve springs, this are our least expensive dual spring kit: http://store.cammotion.com/catalog/p...cbfba573238628
