Launch, that is a nice setup! I agree with you on the stroke. Keep it 3.622. I personally have always preferred to keep a motor over square. If you put a 4 in stroke in there you will make the same power but with 30-40 more torque. If you do stroke, sleeve it and punch it out to 4150 or so. My opinion. Honestly, I wish Chevy had not stuck with 4.4 bore spacing and had decided to go 4.5. Woulda made the block a half inch longer and wider. But think of the options and what that would have done for the platform.
Your heads sound like C5R heads. They were a really small ls7 style port but still flowed amaze *****. If the top ten fastest NA lost in the racing section is still valid, check out how many are C5R heads. Maybe that will be worth some motorvation?
It is just not in the cards to swap out the rockers. I am too close to getting it running. Plus the springs were chosen with the YT mass included in the equation. So, it is not as simple as swapping out rockers.
@Bortuous, Chevelle posted 11 grams heavier over the top vs stock. It might have been in this thread in the past few days. Not 100% sure. I would be curious to know the over-the-nose weights of some of the other rockers mentioned also. The info might be in the gen3 stickies. I will have to check.

Can't find the info anywhere.
It might be a reason.
However the majority of the time, issues arise because the valvetrain was not set up correctly. Incorrect matching of components etc...
The way Tony has set everything up etc, I would leave it as is. The combo will work very well. It's proven.
Your yella terras will be fine just as they were on Josh B's engine.
His setup was more aggressive than yours with a PAC 1209X spring and was revving out to 7800rpm or so.
He was running the same solid camshaft as me but a 264/276 112 LSA.
Tony has gone over this so many times and clarified everything to the best of his ability.

I will just state that the customer was not happy. As far as the studs? I would assume they were the size that Tony puts on all his 260 Trickflows but i am just assuming.
I paid extra for the 10mm kit and for Tony to drill and tap the grass for 10mm. Not everyone does this.

I would have thought his setup was less aggressive than mine, because I have shorter duration and taller lifts. And I am planning a 8000-8200 shift point. Tony and I had to go to nextek springs because we were not sure the pac1209x would be enough. That was the original plan anyway.
Either way....
Either way....
Last I checked the 1209x has a 500lb spring rate vs 435lb for the next tek.

On the bolts, the 10mm upgrade is not standard. The heads come from the foundry set up for 8mm. Even when I did my 346 I stepped up to 10mmhardware. I personally think it is one of the best upgrades you can do. Especially as spring rates get pushed.

Nextek is higher seat pressure and lower open pressure vs the 1209x. You are correct the pac has a higher spring rate.
Again, what drove the parts selection was lift. Many are afraid to push lift much past about 625-650. Normally it is not warranted.
In this case, we specifically wanted to make sure the heads did not stall so we could run higher lift to get increased duration at moderate lifts. It is quite aggressive. Just does not need 600 lbs open pressure to control with the very light valves.

How much seat pressure are you running?

Thats right.
Lower than mine because of titanium valves.
You have 94g in less weight on the intake side.
Not sure if it's been said already, but what is your rwhp goal?
I'm hoping for around 700 on this setup.
Titanium valves will add about 12 rwhp after seeing one of Mamos customers do this.
I have a feeling the low lash solid may not make quite as much power as the comp cams version.
I remember asking Tony about it and he was very confident to go the comp cams route because they have worked very well for him. Who am I to not listen? So I went ahead.
I like the customisation cam motion offers though.
You can choose the duration and lift in increments.

No real HP goal. More of a 9s NA goal. But not your typical track car.
Track is an hour away. I want to be able to drive an hour to the track, rip a 9.xxx pass, and the drive an hour home.
My previous build with the LPE top end ran 10.1@134. I think it had more in it, but I also figured I could pick up 50-70 hp via top end magic and make a 9.xxx a bit easier to do with poor driving skillz
