Oh yeah? I thought they were pretty rough... I still havent totally decided on what I'm going to go with. I still have a week or so to decide. They say the f11 will make around 410 ish with my setup, and the F13 will do about 20-30 more....I just want it to last a long time. What lsa should i go with? i was aiming more towards the 114

 

I had the F-15, and a few local buddies have the F-14 and F-13.

Overall, they are great cams with great driveability.

Even with the F-13, it'll still be very driveable. The 112 will lope harder than the 114 LSA and make a tiny bit more power/torque.

 

Did the prob with the defective F13 cams get resolved? There have been some nice rounded lobes and destroyed lifters connected to the F13.

The XE lobe design is a Comp cams lobe. Used on the old TR224 etc. The Futral cams have some pretty good lift with their durations. They're more equivalent to XER lobes. Take a Futral grind w/ 224 duration, they have .588 lift. An XE lobe @ 224 had .563-.566 lift and the XER have .581

 

I have a F11 that was tuned by Alan Futral last year,it only has 2300 miles on it since then,but on a full bolt on SS through 4.10's and 17X11 ZR1's it made 408/390. It drives almost as well as stock. It is a great cam for a DD! If anyone is interested a have a set of Harland Sharp 1.7 rocker arms that have less than 2K on them. I have a new motor going together and wont need them any longer PM me for a great deal!!

 

pm sent, But I've heard people having problems with harlands cracking and such with XE-R cams from some other fbody board. Were these on your car? how did they hold up?

 

Save your $. Your stock rockers will be fine.

 

They are right in the middle between an XE and XER lobe. I believe the advertised duration compared to duration at .050" is around 51-52 degrees.

It was Cam Motion's problem. The cores that were being used were defective.

 

Well, when I put this cam in, w/ the LS6 springs, I didn't have any plans on rockers. But after I seen how time consuming it is to put the springs on, maybe I should have gotten better springs.

So the 1.8 rockers would really give me problems down the road??? Even though this is just a cruiser?

Thanks for the input

 

Only if you want broken springs. Had a friend that had a 918 spring break which caused the valve to drop. The only engine parts that were salvagable were 1 head and some pistons and rods.

Thats the problem with longer rockers. The cost to up grade to them will equal a new cam with the lift already ground in it. This makes the hot cam kit not so great of a bargain. Thats why I say, there are better grinds out there.

 

Cam Motion's prob became Futral's.
Saying it is someone else's prob is like saying the weak 7.5" rear is the problem of the person who decided to use it behind an LS1 instead of GM's or the optispark was Delphi's problem instead of GM's.

No it isn't Futral's fault, but it is their problem.

 

ya maybe you should pull that hotcam, up the springs, and sell the hotcam/springs with proof of purchase/milage on ebay. You could get what you paid!

 

Or since you're happy with it, then just run it as is. Its already in. Just skip the 1.8 rockers, but you'll still have to check the springs every so often. When they're worn out and you have to change them anyway, put better ones in if you want to run the rockers.

 

Sorry to confuse yall!

I didn't pay anything for the cam, it was new as well. I traded some machined parts for it w/ a friend. He also installed it for me, and didn't charge anything. He helps out anyone he can in our club, and is a great friend.

I didn't invest anything in the cam except some time, and good food I am not going for power here, just a fun crusier. The only thing I had to buy were some gaskets, and the LS6 springs. I know changing out the rockers are pretty easy, that is why I asked. I wouldn't take a chance breaking springs.

I know that the hot cam is not an aggressive super lobe cam, and it doesn't have to be repeated over and over I just wanted to see what everyone else had pulled on the dyno w/ it, w/ some other bolt ons. The car is an A4, btw.

Honestly, before I invest any more cash in hp parts, I would rather get it paid
off (next year), and save up for the new Camaro coming out in a couple of years

I do appreciate all the comments and great suggestions though! I couldn't have asked for more

 

well ya if you're happy with what you have then thats great! just enjoy it and maybe have your springs pressure checked in 30k miles.
