Dynotuned 416 LS3 Today My build
New LS3 Block
Balanced rotating assembly
Molnar Technologies 4 inch forged steel crank
Molnar Technologies 6.125 inch forged rods, ARP2000 Bolts
Wiseco 4.070 Forged dome pistons, -3cc valve reliefs, 11.6:1 CR
Cometic 4.080 inch, .040 thick head gaskets
Arp head bolts
Stock LS1 balancer
Gmpp CNC LS3 heads, new
BTR .660 lift valvesprings
Stock rockers w/ comp trunion upgrade
Comp 7.425 pushrods, 5/16 .080 wall
LS7 lifters
JP Performance single billet 1x adjustable timing set
Melling M295 ported oil pump
LS3 valley cover
Improved racing oil pan baffle
CamMotion cam by Martin at Tick Performance 242/256 .630/.611 113+4 LSA, cam degree'd
Stock LS3 intake
Stock fuel rail
Stock LS9 Injectors
Warr Performance 92mm TB
TSP 1 7/8 LTs w/ ORY into GMMG catback
Racetronix 255 fuel pump w/ hotwire kit
MWC 9 inch w/ spool & 4.11s, PST steel DS
Car made 485/457 on a Dynojet. Has LS7 Maf setup but was tuned in speed density. Its not a very generous dyno, made 400/380 on the same dyno with the 5.7 setup, TFS215s, 228 cam, Ls6 intake 3 yrs ago & the car went 11.50s @ 120. I'm sure the 4.11s & 9 inch don't help the #s & true duals would free up some hp. I'm not too concerned with the #s that much, will get it to the track soon see what it runs. Car feels really strong!

I'd like to do that but don't really wanna cut the intermediate pipe up, part of the gmmg exhaust. I'd like to get the TSP true dual dumps that slide right on my headers. They were like $270 on ebay but I couldn't find them last I looked. I'm just gonna run it like it is for now as it's got such insane acceleration as it is!

I see this was at Jakes Performance. Are you sure about it being low reading dyno cause my buddy's HCI LS1 made 445 rwhp on that dyno. It had PRC LS6 heads, Vindicator cam, LS6 intake with long tubes and full bolt ons. It had stock 3.42's on a 6-speed as well. Wouldn't worry about the number...see how it compares to your old 5.7 at the track

The guy that tuned the car said its the most he's seen one of these make. I don't know if he's for real about that, maybe he hasn't seen very many LS3s in Fbodies. He kept saying "In the real world!" lol! He did say its a good combo & the car doesn't have a dead spot at all!
[QUOTE=flintwrench69;18936943]Does your buddy have a black 02 z? I seen one there 3 years ago at a dyno day. The reason I say this dyno isn't generous is I only picked up 20 whp with a set of Trickflow heads with my LS1, & that was over my cam only on a mustang dyno at Vector. But I also went from a 10 bolt w/ 3.73s to a 9 w/ 4.11s & that robs more power. I figured I would be around 500whp & 470-480 tq. Don't care though, the car flies!

[QUOTE=HCI2000SS;18937119] I was at Milan last night for the Mayhem race. Just spectating though. Still breaking the motor in on street tires letting these guys with a tire on theirs get out on me before I freight train em lol! I'll get my tires on soon & make some passes at Lapeer. Going to No Ets at Milan next month.
Yes they do! Needed a new bottom end anyway after spinning a bearing, figured it be worth it to kick it up a notch! A set of TDs will help.

Congrats on getting it going. For what it is, not bad at all and I bet its completely streetable.
When I look at this setup, reminds of what GM should have put in that car from the factory.
Looking forward to ET/MPHS.

No. Sold them & the rest of my top end to get the LS3 stuff.
Yea with that & an UD pulley I'd probably be over 500whp. Didn't wanna spend any more $$$ & I've heard some run hotter from the water pump not spinning as fast. Not in a big hurry to get the TDs, may not be until next year. Wanna see what it does like it sits 1st.

Its very streetable, doesn't drive much different than my old setup, just more power. Uses a lil more gas. Was gonna put the A/C back on it but since summer is almost over I probably won't.

I bet it runs awesome the way it is. A couple things I remember after getting an UD pulley years ago were: runs a bit hotter(as you said), voltage dips at idle, & a/c doesn't perform as well.
