    i'd do better heads and a larger cam plus the E-Force. C6 guys are getting 600+rwhp out of LS2's.

    Re: What mods next? Maggie? Cam?

    I've thought about something similar myself...heads, cam, supercharger (E-Force FTW). Has anyone spun a bearing pushing 600whp? That's about, hmm...750hp at the crank. Can the transmission handle that?

    Those 2 items keep my bank account safe The "clunk" is dangerously approaching my funds for the CS rear-end mod though!

    if you are gonna leave all the internals stock i wouldnt push for too much, then it will an expensive rebuild...Stroke her to a 383 and try and hold that power down, then if you feel the urge slap a SC ontop and love it...

    Not sure what impact the LS9 cam would have, but assuming you're committed to a maggie, the next step could involve doing an LS2 throttle body (you'll need an adaptor and harness) then possibly an eight-rib, over-size (8") crank pulley with smaller (2.7" or 2.6") drive pulley, finally a nice dyno tune. I was poised to do this after my maggie, but chickened out. My car runs so well and is so reliable at present, I just didn't want to risk mod hell.

    I hate MH.

    Snout comes from Magnuson. Casper electronics for the adapter.

    Got my adaptor from Hendrix, but I'm sure he doesn't stock them on any regular basis. I'd take OneFast V's suggestion and call Magnuson directly. My 90mm TB and harness was a takeoff I got from Katech, again not something they'd normally stock I'd think. You might have to search around a bit for those, but I'm sure they're out there.

    The money involved with switching to a 90mm TB isn't worth the 10hp you'll gain if you go the Maggie route IMO...

    Re: What mods next? Maggie? Cam?

    The 90mm throttle body has been proven to not be worth the expense...5-7whp for $500 throttle body and a $200 adapter. The throttle body is not the restriction on FI that everyone seems to think it is. Take the $700 and put it towards a 100 shot instead.

    A Maggie and LS9 cam is a really good choice for a nice reliable setup. I moved on to an E-Force but you have to know what you are doing and have a bit of vision and fab skills to pull it off. I did mine for less than the cost of a Maggie, although I am still refining it.

    The Maggie is nearly maxed out on stock cubes so no need to waste money on a crazy cam and/or heads.

    I think the LS6 cam is fine for a Maggie... The fact that its a furnace is the limiting factor... Unless your dead set on changing the cam or have a reason to open up the motor then I'd leave it... Again it's cost versus gain... I'm at 475/472 with overdrive lower and 2.75" upper... I doubt much more could be had with a cam/TB upgrade... Now if you run e85 or nitrous... Then it's a different story

    I gained 25 rwhp (correction: 15 rwhp) off an LS2 throttle body alone (on a maggie LS6) with the dyno sheets to show that. Also got my throttle body for rough $200 and adapter for $50
