Question Any other cam for f/i

IM GOING TO PURCHASE A NEW CAM FOR MY BLOWN 4.8,I WAS AIMING TOWARDS THE GT2-3 SINCE ITS THE MOST COMMON,PROVEN CAM FOR F/I.

BUT I JUST LISTENED TO IT AND ITS REALLY QUIET

GT2-3 is proven. If you want to go a little larger, use a similar LSA and intake/exhaust split. Nelson tuned your current setup.....I'd break off a phone call and see what he thinks. He knows a little about what you're trying to do. He's a good resource. Use it.

With a Radix I wouldn't go very big on the cam. Stay mild. It'll be quite fast on that 4.8L with just a mild cam.

A "choppy" cam will make less power with FI, but if your after sound and not power, then look for something in the 110-112lsa range. It will have more chop but make less power. If you want to make POWER, look for something with 114-117lsa range. It will be smother, but make more power. NA cams are choopy at idle so they're more efficient at high RPM.

OK, I think I know what you might have said, but I'm not really sure what you actually said. I kind of agree with it, but I'm not really sure. Could you rephrase it a little>..I'm an old fart....type slow.

A lower (numerically) LSA cam will bleed boost making less hp in a fi motor. A higher (numerically) lsa cam will run smoother and make more power in a fi motor.
