I shift mine at 7k with a much smaller cam.
Well, my counterpoint would be to send a msg to sticks n stones to see how he likes his dirt cheap L99 head swap. Dirt cheap. 450 or 475 rwhp if I remember right. Dirt cheap.

Got a buddy that went to school for machining that's done his dad's racecar, his turbo shortwide, and the heads on his sister's racecar that's gonna do them for me once he gets back into town.

450whp is easily cathedral territory. ....unported at that these days. My buddy phil made over 450 back in 04 with gmpp 243 heads on a 346 with a ls6 intake. With what we know today and the parts available we could likely do 500whp on that same basic engine.

Should I just get my LS6 ported, or should I spend the coinage and get a fast. I'm kinda a tightwad...

It all honesty the ls6 isn't terrible. But by the time you spend the $ porting it you're better off with the fast intake. The ls6 won't match it's power anyway ported or not.

I did 440 with a super loose converter with ported cathedrals. I am sure if car was an M6 that would be 460-470.

07BlackSS, you seem to actually like your wife. You say she set the titty job aside so you could get the SS. If I were you, I'd simply get the car tuned, running correct so its not running rich and just enjoy it for as little cash as possible. And maybe set near future coin aside for her to enjoy and worry about upgrading go-fast parts for the car later on.
My better half currently would like to enhance her upper region and I would like to get another vette or Harley (she wants the booby job far more than I). Since the road goes both ways under my roof, I'll be banging bigger **** before I'm banging new gears.

Good run btw, even though it didn't go as expected. Thanks for posting.

sell the LS6 and pick up a Fast...it off sets the cost quite a bit. On FB there was a guy selling a new Fast90 that was a demo unit for 5-550.00. Just as long as your buddy knows LS engines that is fine...it's not the same as porting SBC or BBC stuff.

Nice run, man! You were pulling good. If he did not jump you would have walked him up top, no doubt. I think a little more gear with a good tune and more rpm, you would walk him easily.
I run a 4.10 gear and shift at ~6800-6900 rpm. A 3.42 gear and shifting at 6500 rpms is not giving that motor a chance to show you what it could do.

Yeah that's what I think we are going to do. She deserves it so I'm going to give her what she wants as she did for me. Thanks bud

Yeah he has a 5.3 turbo swb chevy making 650whp that he built in his shop. He's only 23 too. But gotta get the wife to open up her purse strings again lol
