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

IS THERE ANY OTHER PROVEN CAMS FOR F/I THAT ARE CHOPPY,TO WHERE YOU CAN ACTUALLY TELL ITS CAMMED??

 

sorry been waiting to use that

 

lol,sorry about that,i actually got banned from sss.com for using caps-thats dumb!!like if its gonna kill them.

anyways back to subject

 

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.

 

ck out speed inc, im using their TU1 cam and it works really well!!

 

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.

 

my cam in my sig. actually has a decent idle for a blower cam
