Another AFR & 224/228 Install After a year of casual deliberation followed by 3 months of serious trade studies on cam selection and countless IMs to guys like Sidestep, Tony Mamo and Patrick G- I decided to follow the widely known AFR recipe, with one small variation with the mill to .030 for a tad higher compression (ok-ed by Tony for the land of 93 octane). Seemed like the right set up for a 99.9% street car/summer daily driver that gets a ton of bumper to bumper traffic. So 2 weeks ago, I put my car up on the jackstands and my buddy and I start tearing it apart. After a few nights of 2 to 3 hour work sessions and we buttoned it up on Monday. All went well for my first cam swap.... Final activity was a quick injector swap in the parking lot this morning at Speed Inc. and I handed the keys to Jon and Larry and let them do their magic.
The net result was a 429HP & 392 torque. I think thats pretty stout considering I have some heavy *** repro wheels/nittos, a 4.10 rear and running cats. I think my torque would go up nicely with a set of LG headers- and I know the fast 90/90 would be good for 20 up top, maybe midrange too if Tony would port it for me- but I am now flat broke for the summer so needless to say, I'll be enjoying my current power levels for the time being.
For what its worth, I got 31mpg on the way home.

Tq curve is nice and flat just like mine. You will kill alot of bigger cammed cars on the street..believe me!
Im having my car retuned with speed density by ECS. Ive seen the results off an LG gs-x3 cam and AFR heads combo vette that had an LS1 edit tune previously.... freakin thing idles smoother than my setup! and he picked up 10 rwt! 11 RWHP! EFI Live opens up alot more tables for the tuner to really tune the car the best it can be.

I think you could find a little more power with that combo with a little more time on the dyno. See sig, all tuning done at Finish Line Performance by Dan Bills.

I'm having some low speed surging that I think is because of the injectors. Long story about why I have 42s, but the part throttle jumpiness I sometimes experience is something I'm wondering about. Not sure if it can be tuned out or if the 42 is just plain to much injector.

I was afraid of the 4.10 at first... gas milage, short shifting, etc. Man, I tell everyone it should come like that from the factory. Only way I'd stay with 3.42s would be with a blower.
Take care man-

No flycutting here. Funny, I started out with a bigger cam- say F13 type specs and gradually worked my way down. I even toyed with those LSK lobes that Patrick G. first posted about but no data and valve spring concerns pointed me back to the tried and true 224/228 on a 114. But all along, flycutting was never in the books for me. I was nervous enough just doing the cam for the first time, let alone putting smilies on my pistons.
I know that Tony had seen evidence of PTV contact, but it was real minor and he had lotsa miles, multiple track days and 400+ dyno runs to 7K. He wasn't concerned about it and I'm not either.

I like Dan and his reputation speaks for itself but I didn't want to be lugging back and forth to Aurora (hour drive one way) every time something comes up. That's why I went to Speed Inc.

Depending on where the surging is at, it could be part of the package or it could be something that can be tuned out. That combo should really drive almost like stock.
Congrats!!

i run 42's on mine and it runs very smooth,no injectors will give you suring/bucking,but a tune that isnt real good will.you need to have them go over the tune with a fine tooth comb.
