- My car is back! We changed the cam and ended up having some issues with the trick flow Ls3 heads so those are gone. The car now has completely stock Ls3 heads (unported unmilled) with a set of used BTR 660 springs on it. The car is still the 416, the same torque converter as before, it also has the updated BTR Trinity, we redid the fuel system since the old combo was having weird fuel pressure issues.
2008 4lt base LS3 based 416, stock ls3 heads, BTR custom grind cam blower cam, BTR Valve springs, BTR Trinity intake manifold (unported), NW103 throttle body, Wiseco pistons, K1 rods, K1 crank, Johnson 2126lsr lifters, ARP everything, Circle D 258mm converter, 6l80, stock 2.56 gears, kooks 2" headers, 3" xpipe to 3" dumps, modified vararam intake, fuel injector clinic 60lb injectors, twin walbro 450 pump, ati 10% UDP. Racestar front runners with M&H front runners, rears are 275/40r17 M&H drag radials for the first few passes then I swapped to the 275/40r17 Hoosier DR2 drag radials, GM flex fuel sensor, this was on 75% ethanol, BST C6 6l80 Differential Brace.
DA was around -300

this actually are really interesting, theres not alot of car doing 9's with NA engine
Agree, I went 10.2 with a heads cam combo on pump gas with a little more weight in the car. A basic heads cam combo with either some compression or weight reduction should run 9s easy. Or even a more extreme converter will do it. This has the mph for mid 9s I just need a converter that hits harder to do that but idk if I want to go that route.
You have her BUILT!!!!!
It gets down for a legit full interior still has AC, Heated seats, power steering, hell even has a radio with an amp and sub.
@andrewd843 Friggin nice!!!! Yea I am not stripping my car to make her faster. I see people do that. I'm not looking for max all out horse power or times. Lol. Those who do that's fine. I'm not.
MAN Fayetteville looks different. It looks alot cleaner. Man, it used to be beat
I haven't been in a while. It always seemed to get better a little bit, and then it would get worse, always changing with different management.
Good stuff man. Wish I could get my sbe ls3 to run as hard as this 416 setup.
It's definitely doable. I was running 10.2s heads cam sbe ls3 on pump gas, and the car was heavier.
@@andrewd843 we’ve talked a lot and you have shared info with me. My sbe bes ported ls3 head btr4 cam car has been 10.35 at 132.xx so far in about 500 positive da. Car just wouldn’t 60 any harder. It weighed 3200 on the line that day. I finally got it running better then majority of guys with that cam selection tho.
Slow down man, that’s quicker than my turbo car
Once it can 60ft should be a lot quicker. I was running 9.7s years ago at 137 but a 1.3 60ft on a different combo.
Badass! Is that the converter I hear locking up in 2nd gear?
I wish I could copy that cam and compression sound on my turbo sbf. I know the side barriers add to the echo, but damn that thing sounds amazing. Wish I could get something close to that sound
Those turbo mufflers really kill any sound it could have too
Locking the converter in 2nd seems to kill the 2-3 shift?? What ET will it run unlocked?
Nice runs though sounds great!
I've done a lot of testing with this only changing converter lock. It drops over 1/10 and gains mph locking in 2nd. I've spent a whole track rental only moving lockup mph and shift points. I've ran completely unlocked, locked 3rd (all sorts of lock points), locking 2nd (all different mph)
I've even done the lock it and unlock it then lock it back to test.
@andrewd843 I figured you had and assumed it would pick up some mph locked, seems to be holding it just fine too.
What converter/stall size and gear were you running?
Stock 2.56 rear gear. Converter is a circle d 258mm. It's around a 4k, but it's not great with this combo. My old "3600" Converter would 60ft better with less power and a heavier car.
How high are you shifting with those .660 springs?
This was 7200-7300ish the stock heads are hurting the power up top. 660s are good for some RPM NA as long as they're shimmed right, with light valves, good lifters, on a good cam profile. I wouldn't try taking some 660s 7k+ with something like a trickflow head that has some 110g+ valves.
i saw one comment on your previous video did you end up replacing your transmission with just a stock rebuild?
Are you starting in 2nd? Trans is stock jesus ive had nothing but problems with mine
Most likely a tuning issue if you keep having transmission problems. The best build transmission will fail fast with a bad tune. My other car makes way more power is faster heavier and has 100k miles on the stock 6l80 now without any issues yet.
That's the truth had a so called tuner out of Dubuque IA mess my century built 6l80e up with a bad tune when I specifically said do not mess with tcm tune but did it anyway $7,500 plus the junk tune waisted
@@Jasonspot68 I’ve had multiple tunners . Fully built trans and its in the shop again as of today for the 4th time
How you like the btr manifold?
I like that I didn't have to cut the hood. The BTR manifold is great for combos that need it. Most people don't need it though I went pretty quick with a stock intake and tb back in my heads cam days.
What was the issue(s) you had with the TFS 255s? Those are supposed to be hotter than Salma Hayek in her prime on any LS3-based combo with a proper cam and valvetrain. Asking to learn (and building my 402 out this year to something nastier).
Do you know what the car is putting down to the wheel?
Weight/mph and weight/et both say right around 600whp which fuel consumption agrees with too.
Did you have to do a return style twin 450 set up?
Yes, sir, I have a fore dual pump setup now. I had the Racetronix drop in single 450 but kept having pressure issues with that. My stock pump did better than their drop in 450.
@@andrewd843 uh oh that’s what I have, shooting for 700 wheel on E85 NA. I’m sure you had the Hotwire kit and all?
Yep, had the same issue on multiple cars with that drop in pump, a few went back to stock and didn't have issues, mine and a few others did either the fore setup, or the Chris1313 Racing Inc (that's the facebook page name) dual pump setup, and all issues went away.
@@andrewd843that’s freaking junk. Yea I know of Chris’ set ups I’ll probably plan to do that on mine. Thought about a BAP but that will probably just be another headache
@corvetteZ3r that's literally what I was going to do. But I didn't have issues on the stock pump.why put a bap on a "better" I even bought the BAP but ditched that idea.
What issues were you having with the old heads?
Valve issues, guide issues, plus mine seemed to be made of paper mache, there's a lot of post online about 255s and issues they have.
Is this still the kooks headers with npp exhaust?
In this video it's kooks with 3" dumps. But it still has the npp mufflers 90% of the time.
@@andrewd843sound insane my apartment complex is gunna love it!
What's is the compression?
How much did you gain from the pray ported heads?
I don't have pray ported heads. My heads are completely stock untouched other than valve springs.
And they say NA cars don't like lockups... 😮
Some don't that's for sure. But it depends on the converter and combo. I've locked plenty of converters and the car slowed down. It's all about the testing.
