413/393 on stock LS1 heads Man I am happy. I don't know if you guys remember me posting about being somewhat unhappy with making 388 awhile back.
Here is the old thread old dyno info
Today (in 80*) weather. I dynoed 413/393!!
I added a 3" true dual H pipe that Lane and I welded up. And I went from 3.23s to 3.73s. Those are the only changes and I have no tuning.
The cam is the TR230
I dynoed at Fastech/Speedtek in Dallas. They didn't have any printer ink so I won't be able to get a sheet till I guess tomorrow. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: 413/393 on stock LS1 heads My friend in his 436/486rwtq 03 Cobra showed up afterwards and we ran from a 5mph roll. Initially from the punch the Cobra's 486rwtq launched it out and put my nose at his door. When he shifted I took the lead. When I shifted he got even. Through the top of third by the time we shut it down I had him by a nose. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
This cam is the best ever!!!!

Re: 413/393 on stock LS1 heads Thanks for the compliments guys. I can't wait to get a ported TB. On my old Hotcammed Z28 I gained 6/12 with one. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Re: 413/393 on stock LS1 heads What were the weather conditions for this dyno?
Is that TR230 cam one of the reverse spilts?
What are the specs?
What was your cat back before going with the duals? How loud is it now?
Sorry for all the questions, but dyno numbers like those perk my interest.
Kick *** numbers!
