Sounds good man. Keep us posted on the whole deal. You should be happy with the whole new intake/tune & super damper. Your power doesn't even look like it peaked yet on the dyno chart. I had the same problem one time. The guy wouldn't rev the thing out. I want to see how far my power carries & how hard it falls & where.

I’m with you guys I’m going do a fast intake I rev out at 6500rpm so no point for msd intake. Will see what I can make out of it. Also do ati superdamp, switch to speed density, and maybe do bigger lid. See if I can unchoke this motor make most out of the set up. I’ll be extremely happy hit around 470whp with this cam.
Will see what this set up will make if I’m still itching for more then I might look into doing different heads.
I knew going the 383 route wasn’t going be the easiest way to make big power, like most the 400+ ci. I do love having a motor that’s period correct to 4th gen fbody.

If you can't make 470 with that take it out back and shoot it.
LOL
Oh and the super damper sounds like a great idea, under drive be nice to free up a little power. Revving it to 7k may make it a little faster depending where you land in RPM when you go to the next gear.
What wheels and tires are on it? A lightweight drag setup can make a considerable difference also. Running bias ply slicks will free up a lot of weight and help that 10 bolt live also.
I have to say I like your style, running a stroker and a 10 bolt with a 6 speed.

Lol Blind Faith it is, I’m hoping no digs or slicks it’ll last.... If/when this built 10-bolt goes I’ll probably do a 8.8 so I can actually do some drag for fun again.
Best wheels ever. I had those on my 2000 SS. But you need 315's out back! Either way car looks damn good and is lowered just right.
For your driving you don't need slicks and avoiding digs is a good idea but I'll go on a little rant about slicks anyway lol
It's counter intuitive, but slicks greatly help the 10 bolt last. The soft sidewalls absorb tons of the shock load, shock loads are what break them. That's why autos don't break the 10 bolts near as much as a 6 speed, no shock from banging the clutch. Hooking isn't the problem, the slam from banging the clutch breaks them. Picture it like pushing on something vs hitting the same thing with a hammer. Try pushing a nail in, that's what an auto does, it pushes, clutches hammer. The soft side wall slicks absorb the shock. I know several people that have broken rear ends on street tires and drag radials that had no broken parts with slicks, even launching at the track.
Think about it, you can hammer it in first with it in gear, it hooks and goes and doesn't break. Pop the clutch from a stop though.. Some guys are real good at slipping the clutch on a launch and can make them last too, but that's pretty hard to do and one oopsie is all it takes.

I had a 383 that made 534rwhp through a T56 and an 8.8, 518 SAE corrected. Used hand ported Dart 225s with 2.055 valves, 243-251 112 .624 Custom ground cam, 1138:1 SCR, Edelbrock Pro-Flo with ported opening 42lbl LS3 injectors and 105mm TB, 30 lb MCLeod flywheel , they can make power. I also noticed this motor made more power than most 408 builds in Dyno results.
I broke a 10 bolt.. with an auto.. just hammering it from a roll in first gear. It was in the middle of the day on a busy street and pieces shot out of the rear end cover. It blew up in spectacular fashion. Funny thing is I drove it back to the shop about 8 or so miles away with it trying to lock and banging the whole time. I got it there and pulled the cover off, pulled some chunks out, slapped the cover on and banged the holes in the cover back in with a hammer and put silicone over them and drove it to the rear end shop a good 10+ miles away lol.
Now THAT takes talent lol.

When you said you broke a 9 inch I was like whaaaa. The yoke I can understand though, the rear itself is a much harder thing to break
yeah, can't say I've seen 1 shear in half before. But thank goodness for driveshaft loops. Replaced with a billet yoke and took my 3800lb car 1.5x a couple times lol.

Dose anyone have a preference of MSD vs Fast 102? I've been reading alot between the two seeing that MSD slightly out performing across the bored. Trying search more on Ported MSD and Fast results. Right now My motor reves out at 6500 peak power was at 6000 with ls6intake of course.
