I want to get an idea of how these cams will differ. All three have been recommended for my Radix'ed LQ9 from different shops, and all three seem very different. I am interested in idle characteristics, low end torque characteristics, and high-end power characteristics. Also, what RPM will they be good up to?

1. LPE GT2-3
207/220-571/578-118.5

2. Vinci Trucker (what I have now)
216/224-551/551-115 (with the 1.8 rockers I am getting about .583 lift int and exh)

3. Futral recommendation
224/226-580/575-114


I don't really like the idle quality of the Vinci cam I have now, it is a little too chunky for me. I have been having issues tuning out the RPM drop when shifting from P/N to a drive gear, and have been having issues with the a/c tuning as well. I need the new cam I get to have good idle characteristics as well as kick-*** performance at the track. I know that a lot of you love the LPE cams, but I want to get some details on what to expect with any of the setups listed above. I am leaning towards the GT2-3 right now....just want to make sure I consider all the options before I order.

 

Just to clarify, my truck is my DD and I tow a bunch during the summer. I will sacrifice some top-end power for good low-end torque, but I don't want to give up low end for top end. I want a good balance with the emphasis being on the low-end.

 

My gt2-3 will be going in my lq4 hopefully by the end of the week if I can get the cam in time. Currently on backorder.

I will let you know how it feels. Felt awesome in the 5.3.

 

If Allan Futral gave you that rec based on your setup and needs/wants/uses of your truck, then I would go with that. That is a custom recommendation. The LPE cams are proven performers, but personally would still go more towards custom by a reputable cam designer. Futral is one of the best, if not the best at it in the LSx world.

 

Not sure if it matters, but it was John @ Futral that I talked to. Should I call back and talk to Allan?
