Default fly cutting g5x3 112?

Did you guys running this cam have to flycut the pistons. Im thinking about getting this cam down the road and kinda wanted to avoid flycutting if possible may switch to 114lsa

No need for flycutting. I currently run one(comming out here shortly) and have been for quite some time. Depending on the aftermarket heads*optional* you could safely run this cam with milled afr's/etp's.

Just be aware that G5x3 on a 112 is very/very tight on PTV. It is advised to flycut on that cam.
Look less than .080 intake and .100 exhaust PTV in a street motor is pure suicide on the street, so unless you can afford a new motor, avoid pushing those tolerances at all cost.

I will bet you big money that you have eyebrows on your pistons. Comments like this are pure ignorance.
"Uhh, I did it and it is fine!!!"
Guys, it is very simple, there is such things a minimum tolerances in motors, so either do it right and enjoy tons of power with reliability, or; Well, you'll pay the price. That is a for sure, not a maybe.
I am even willing more bets that yak didn't degree his cam or checked his PTV tolerances. He just stuck the cam in dot to dot and called it a day.

pretator z im not trying to start a flame war here but I think your comment is a little out of place. I explain my experiances. as you can see a lot of people on here run this cam and have no problems. I didn't degree my cam because I did it per LG's specs. I know you like to bash this cam based on your previous posts and I think you should just stop. Do you think majority of the people who do cam swaps in their garages degree their cams? If I had the known the specs before hand I would have degreed my cam, but I could not since they were unknown, I put the cam in and must have turned the motor over 100 times by hand to make sure it cleared. Ask SLPcars98, he was there when I did it.

oh and by the way, if you don't think i'm crazy wait until I spray a 175 shot on the stock bottom end. you don't go faster than everyone else by being a little girl.

Your a legend in your own mind

How fresh are your valve springs? Without knowing the specs of the cam its a really tough call but my guess is that its too close for comfort. What did LG say about it? They should know. Some people take chances and others don't. But using the "it works so far" line of logic is just plain stupid. If your tolerance is to tight and your springs degrade just a little then what do you think will happen smart guy. I argue with Pred from time to time about cam choices but he's right about what he's saying here. You can either play safe or fly blind. Its a personal choice. or get 11 degree heads

Man, don't feel bad, LG themselves don't even degree their cam install.
And, no I can't stop, because I'm a firm believer that experienced poeple should help and enlighten the amateur consumer.
The 234/242, .600/.610 112 is too tight on the piston clearance. It is a recipe for the inevitable.
Sticking a cam in (especialy that tight) and not measuring PTV, is just the wrong way of doing things.
Pistons are no all at the same height in different motors, heck nothing is exactly the same from one motor to another.
That is why building techniques were established, to verify those parameters.

So, YES, I will continue to say the truth, the way I see it. I'm not bashing LG, I just said that the G5X3 on a 112 is TOO tight on PTV and it is ADVISABLE to flycut. Otherwise be ready to pay the price.

BTW, that cam is overkill on stock headed motor
My apologies to you if I came on too strong (I thing I did)

I think it will be more like as much as the budget allows, looks like I'm gonna settle for a 347 (forged), PRC 2.5 5.3L heads (60cc), 228/232 cam and juice again.
I dunno, I need to get my hands on an extra $$1500, I wanted a 383. all that is missing now is the shortblock.

You'll be making some good power. Those heads are working pretty damn well for me!
