Generation IV Internal Engine - Another LS3 427 cam question
04-05-2011, 01:57 AM
2010 Camaro currently has CAI, LT with offroad exhaust and tune, with it's current cam it was at 440 HP 420 TQ last summer on a dynojet.
Cam details: 277LrR HR13 (http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1427&sb=0)
Now I'm looking at going 427 (4.1 stroke) at 12:1, with ported heads, throttle body and maybe intake. Car is a weekend/summer driver, and would like to take to the track/strip at some point.
I was happy with the cam before, but should I look at something else or save some money and stay with it?

Too small with 12-1 cr
11.4 and street sweeper would be a better choice.

I'm going with Eds AIR-MAX 16 grind on my 427 at 11.5:1

I don't think I'm going to buy a new cam, but I do have an option of a used(3000 miles) one out of a Z06, with Lift 240/246 Duration .650 .650 LSA 114. That's all the info I have on it.
I'm not going for all out power, must have decent streetability like it did with my current cam (http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1427&sb=0), 227/243 .614 .624 113. Just realize the previous link was the wrong cam.
BTW, manual tranny with 4.10 gears.

Your building a 427 and cheaping out on the cam????? wtf!
Your current cam is wimpy in a 427.
Decent streetability is subjective.
PatG had a 231/231 LSL lobe in his DD 11-1 402
A better method might be - what idle rpm are you comfortable with?
Some lite reading
It has a smaller cam than the 240.....earlier posts had a 234/240.

I have this comp on my Ls3 416
Just my .02, and dont wimp out on going bigger and yes you'll need a FAST the Ls3 wont cut it anymore, driveability is also going to depend on your tuner. Besides its just weekend and seasonal hotrod so go for it!
