lower mounts can provide other issues (like oil pan on front spring & balancer to PS rack), but cradle spacers have done the trick for the lower-profile heartbeat systems. seen 2 of those fitted to C5s with stock hoods. TVS is too tall, though. good news is you don't need spacers with the right hood. if you saw me talking about them earlier, it was because i was gonna use a 1/2" spacer in the blower manifold, which then did require some massaging.Hm I was not aware of this... I thought the blower would only require a raised hood for fitment. Next time I am in contact with the shop for an update I will ask them!

also consider that's 10psi through a large cam, big-valve heads, and 1 7/8 headers to dual 3". good luck with the flex fuel. my show suggested doing an e85 swap, but i'm already *****-deep into my savings from everything else getting did right now.
[/quote]Oh boy... I'll ask my shop about all that. They told me the cam should be fine and offered to custom grind me a new cam, but... said there was no need. But, what you said brings questions to me... mainly about the boost and when it begins losing the ability to get to or hold boost levels...

big N/A cams do better in centrifugal cars (blowers made to exploit top-end breathing), but it ain't as bad as trying to run it in a turbo setup... so don't lose sleep over it.
granted, i still ain't got my car back from phase 2 yet to provide 1st-hand experience, so take that for what it's worth. my blower's been on a stock motor until now, but i have been studying up for the last few years & talking to dudes who've been there trying to learn as much as i can before pulling the trigger on all the optimization goodies this time around. from what i understand, my pressure plateau is due to pulling the plug on the 8rib swap. i've got the biggest pulley they mass-produce (3.8), the C5 kit has more belt wrap than most TVS setups, and the cogs clearly ain't slipping. tuning's on a temporary hold waiting a couple more parts, but last i heard was it peaked at 10psi & then drops a bit up top. tensioner's still tight.

Update: I just talked to my shop and they confirmed the car is now fully assembled (as of 1-30-19). Hopefully I'll have some time in the next few days to run over and check it out. It looks like tuning and playing with pulley sizes is all that is left (for now).
Also, thank you to everyone for the feedback about my cam (MS3)... it started to make me worry about potential problems arising from hitting redline / missing a shift. Due to the size of the cam, there is very little room for error... and I don't want to make a split-second five figure mistake lol. For now, I'm going to keep the N2MB WOT box disabled while I rack up a little more experience with the car one on one lol.

Update: Initial dyno picture attached. We've been having some technical difficulties with the build to say the least. The car made low boost because we were sent the wrong pulley for the cog drive. We ordered a new one so that's no big deal. But... the intake isn't clearing the hood... so I'm hoping there will be a bit that we can shave off under the hood so that we won't have to cut a hole into it lol.
Based off the initial dyno results on low boost, the car should make right around 700 whp. I really want to throw on a 150 shot, but... I don't feel safe doing that with an aluminum block. Not sure a built aluminum ls6 is good for 800+ whp reliably lol.

That sounds amazing. I hope you get all your adversities sorted soon enough.

giggity!
yeah, had i opted for the corn juice conversion, i probably coulda been right up there in the 700s with ya, but i stuck to 93 and expect low-mid 600s-ish. so long as this 3rd a/c line is actually the right one, installs right, and the tuning goes good, i should finally get her back this weekend & see what it actually makes.

The good thing is that if you can always go e85 in the future. I'm afraid of reaching the point where I get used to the power level with this build. I'd love to throw more power via nitrous at my c5, but don't think the block would be able to handle even a 100 shot lol.

yeah, the TVS already hits hard enough... to throw a shot of gas on top might not be pretty with as much as we're already pushing the motors.
Bret already said he's softening my tune up a bit because it almost gets away from you too easily... which makes me giggle inside a little.
... that & mine's still a stock LS1 short block

Looks like the shop ran into more problems with my build... major belt slip with the 6 rib setup. We are going with an overdrive rear cog and the 8 rib swap. My shop hopes the 8 rib will be able to hold 12 lbs or so steady and get my peak HP where it should be. Torque was 600+ to the rear tires so at least some good news. But, they are questioning if switching to a 102 intake / throttle body and / or switching the heads with higher flowing ones would relieve any possible restriction (if present). I'm hoping we won't need any of that because those are two pricey mods... so hopefully we can slap the 8 rib pulley on there and call it a day haha.

likely nearing the point of pulling a little vacuum on a 90mm TB, so it's about whether or not it's worth it to ya...
last i heard was that my stock balancer & 3.8 was slipping above 10psi... and my belt's pretty tight. that's also with OD cogs.
