I have Jay doing a set of 5.3 liter heads. Also going with his cam 227/224 with a little more lift. Hope to get same results. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Congrats

Very nice numbers! I'm getting mine installed right now and the only difference is they are the 5.7L heads. Hopefully my car will turn out that good. Also, what is the idle like and drivability? I want to know what to expect.

Man what a great turn out! 429 at the rear whells is excellent! I have a set of his stage II's ordered and should be getting back soon as well. If I get a similar outcome that would be a gain of 46 HP at the rear wheels. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I'm currently pushing 383 at the rear wheels thru a strange 12 bolt with 4.10's. I'll be posting my outcome as well..

Very good #s <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I'm thinking of getting in on the Absolute head GP. Where did the #s peak? How is the tq down low? I'll be on 3.42 gears. After peak rwhp how quickly did it drop off? I'm intersted in road racing thus the extra questions and gearing choice.
Thanks,
Lamar

thanks for all your input, I am new to this sight and heard this is were the most knoligable people are, I was hoping for 440's with this set up but was not sure if it is possible with the combonation, I am thinking of getting true dual exhaust with cut outs to get a few more ponies, I am not good at reading the dyno sheet but it looks like it peaks at 6400 rpm, the cam is choppy and the idle had to be raised alittle over 1000 rpms

Ed can get rid of the misfire codes. How long ago did you have the tuning done. Was it before the heads and cam???
