I see you have the same heads! How much power did you end up making?? I know I'm leaving some on the table with the stock LS6 intake...... I was going to wait and get a fast 92 but I couldn't take it anymore.

There's a FAST 92mm intake for $570 shipped right now in marketplace if you didn't already see it. You could sell the LS6 and recoupe a lot of that and get a WARR 92mm tb for like $140 and not be out too much money. That's what I'm doing on my H/C/I build.

My tuner does not like those throttle bodies, he recommends the nick Williams. I plan on doing the intake next year and I'll take it for a touch up tune then. I don't think I'll be down to much power.

Replace the lifters while you're in there. And shift higher

Not sure yet. I did have it on a mustang dyno for one pull, but my exhaust was hitting my driveshaft so I didn't get to finish the tune. It put down 450.1 rwhp and 400 torque. I swapped to the Speed Engineering duals, raised the spark from 24 degrees to 26, and leaned it out from 12.4ish to 12.6 at peak torque and 12.8 at peak power. I'm not sure when I will get it back on the dyno, but do plan on hitting the track in about two weeks.

Yep, they are 61cc as well. I'm also running the Johnson 2110 lifters, they're awesome!

I had a ton of room on both intake an exhaust, but usually the intake side is the tightest, and I'm only a 226 duration there. I'm also a 113 lobe separation which helps. From what I understand, however, these have a good bit more clearance than the factory castings. They start life as 64cc heads, and somewhere between .015 and .018 is removed to achieve the 61cc. There are plenty of people running cams your size with that much mill on factory castings, so I'm sure you'll be fine, especially on a 114. Definitely double check though.

And you'll get about 500 more usable rpm with the Fast intake. It does make a big deal.
