It all depends on the setup. I've seen higher/lower on all kinds of different setups all across the internet. The setup I'm speaking of was done with a 2001 Z06 with untouched heads/intake, stock TB, no underdrive pulleys, Vette IRS, no dyno tricks, and on Futral's 248 Dynojet, which usually reads lower than alot of other internet dynos.

Mike, I agree on most parts. New Era's dyno doesn't seem to let most lay down any spoiling numbers either. I can assure you no dyno games were played, since that was a prerequisite for the any shop I was gonna chose. Before too long here we will see what this car will do with the 10 bolt and normal street tires. I agree that the F13 is one of the most proven cams out there, and supporting mods will make or break a combo. Thats why i have seen cam only F13's pull 37x rwhp all the way up to 420rwhp. Now I do think my car can do an honest 440rwhp through the 10 bolt...or very close. After that I forsee some variation of LS6 castings making there way on there with a graph to soon follow.

 

I should have clarified that was STOCK LS1 heads. The 243's are gonna be worth a good 10-20rwhp+ easy.

 

Well they are my only two choices, because they are so talked about on this board ( I did a little research ). Any other suggestions would be cool too.
Looks like I'm leaning toward the F 13 for both cars, or maybe the F 14 for the WS6 and the 13 for the SS.

 

My LS1 had a 224/228 581/588 114 comp cam and OMG it was like the magic number

It trapped 120 on a few 11 second runs and average 118mph on a full weight 99 ta M6.

Driveability was good and it still sounded pretty mean.
