Not a hater at all. I just state facts. Hammer thinks Mast heads are 24 karat gold and they not. 10s is 10s in the quarter but I rather get that 10 second slip with a hydraulic roller and factory rockers.
Low 11s on sbe LS2 with stock LS3 heads/intake with btr stage 3 ls3 cam on a Toyo drag radial. 6 speed 2000 Z28.
Lots of room for improvement but I only have 7 grand in the build . Would had been cheaper if I didn't have a slr lifters, C5R timing chain, titanium retainers and a Schumann oil pump. I cut corners on the used LS3 heads and LS3 intake.
Wonder if the cam was degreed in properly.. Lately it seems to be a common miss by local builders..
I had thought that at first but two things made me rethink it. The peak torque and hp RPM were basically right where they should be. And a 416 should clear 450 RW tq on accident. Its the low torque curve and its shape that point to 346 displacement
Patron- HOW does your post above have anything to do with this thread?
The arguing about nothing.....thought I would change the subject for the better. It seems that some just need to meet @ the track. It's back and forth every thread. If you think a combo isn't that good, I've learned to keep it to myself..... What some consider good another my think it's not optimal. Opinions.

Dude, I do NOT know what you are talking about. This thread is TOTALLY about a guy who had his engine stolen by a shop and put another smaller one in. Put down the joint/pipe/bottle and pay attention...
This thread was about a stolen engine now it's about Hammer build vs Tuskey and how fast he's been. I was trying to just change the subject from the BS to something a little lighter. Me personally I fill for the guy myself who lost a engine to Crooks, but to the other subject it's wasted time and space.

To each their own. I did ls3 ported heads and llsr my self. We shall see what it does soon

True fact. It pulls hard after 4400 rpm or so but before that it's kinda a dog .
LS3 are amazing motors. I made mid 11s on stock heads and stock cam in a 5th gen @120 and now 10.5@131 in my C6. Your 4th gen should be in the 10s on that set up if well thought out.
My built LSA engine did exactly that on the dyno, numbers were 440 where it should be close to 600 at the rear wheels, saw a small electric arc in cyl. #2 spark wire, replaced it and off it went up to 573 right away. The strange thing is it never showed anything when we scanned it, no misfire codes at all!
Hello, I have an 01 trans am with an ls3 416 stroker. Just got done & put on a dyno & made 380ish to the wheels Which from what I’ve seen 416s usually make 500+. And the guy that tuned it said it’s on a mustang dyno & has a stock ls3 intake & that’s usually what he sees 416s make. But I have a couple friends that have 416s and they made around 560 with a stock intake so I call Bullshit. What do you think? I’ll post all of the details about the car, which I know I’ll forget something so just ask and, keep in mind, I’m deff not a car guru, Still learning.
01 trans am
416 stroker built by Thompson motorsports, which build sheet is in the pictures
Stock ls3 intake
65 or 62 lb injectors
92mm NW throttlebody
ls3 CNC ported heads
T-56 6 speed with monster stage 4 clutch
MWC 9” 4.56 gears
Thank you for your opinions.
Three times Tq tried to climb prior to 5225 RPM, an appears to peak at around 5100 +/- a few RPMs. Doesn't that seem a little strange when compared to TQ curve of you far experienced HP junkies engine builders' engines have (By the way that's not a put down to you, just question of, doesn't that seem strange if it's internal engine component(s) problem!).
Is that not strange to you. Engine seems to still trying to make more HP/TQ. Doesn't seemed to have laid down and quit.
No. Torque peaking at 5100 is not weird. The bumps before that are just harmonics/tune related.
The bigger problem is the torque is very low. It doesn't matter if it tries to make more. It's not going to make the 100-150ft/lbs more needed for it to be right.
