I think that's about the jist of it, or at least the majority. But the first trip to the dyno made 736hp/605tq @ 15lbs. Did some tweaks and came back for seconds to make 982hp/843tq @ 27lbs. Hopefully I'm posting this in the proper place, if not sorry. Please feel free to move, its been a while since I've been on. Catch my vids on tiktok(pvosscustoms) & youtube(BS&T GARAGE) 🤘

 

Have you taken it to the track yet? Wonder what times you could get

 

Making some steam and nice straight-forward setup.

I assume head studs and LS9 HG's?

 

I haven't taken it to the track yet, still trying to get use to the power. I have zero saftey/sfi rated anything on it so my first run is likely to be the last. Tuner said if I can hook I'll likely hit low 10 to high 9. So fingers crossed.

Yes, it does have ARP head bolts and an OE thickness head gasket. I did have a set if cometics on it but swapped due to the milling and domed pistons. Just to be on the safe side. Was worried the ptv would start a make out session, and nobody needs that. 😁
