Let me know how that goes! Hopefully the tune is not too far off. The LS flows a LOT of air down low and carries the power curve much further out so I'm curious to know how well the Q jet will work.

You would be hard pressed to run a factory quadrajet on an LS. The ideal carb for an LS is a holley because you can dial in the tune much easier than either a qjet or edelbrock. There are tuning kits out the for those carbs but there's more tuning info on Holleys so that would make life a lot easier. Any carb you know how to tune will work as long as you know that you wont just be able to bolt it on and drive away.
What would you suggest for a blow through carb on a 408 ls stroker at about 10 to 15 pounds of boost? You're kinda my go to for any ls carb talk and videos. Ill be using the Daytona system as well with atleast a 2 bar sensor. Really appreciate the content you put out, you made me want to carb my ls and make it look very simple. Keep it up night wrencher.
Very cool man! I'm not too much of an expert when it comes to blow thru carbs. I do know that CSU pretty much custom makes the best turbo carbs on the market but I would also try contacting PRC carbs to see if they have other options. I wish I could at least recommend a size but carb sizing for boost isnt the same as for NA
I appreciate the reply man, ill check out those brands and talk to some reps. Watching all the way from Wisconsin, can't wait to see those subscribers go up. You deserve it.
There's another option to the msd 614 it's the Dayton sensor set up for a carbed ls , it's the same $$ I wonder if it's any better if anybody knows put it in the NightWrencher comments I bought msd coils for my outboard motor and they came wired wrong when I called them all they did was make me angry. so i'm hoping the D. S. ignition works good
I'm tempted to buy a daytona box. My MSD hasnt had issues but the internal map sensor doesnt work and I tried to get MSD to RMA it but they keep giving me the run around so idk. We will just have to see
@@NightWrencher Yea those msd people think their special. Daytona sensor has a guy named Dennis and he'll take great care with you. I was searching the web because I didn't want to deal with msd and found D.S. and come to find out their only 30 mins. away from me.
With the right tuning I'm sure it'll run fine. I've never seen a carburetor work 100% right out of the box. If it runs too rich, you're fine but if it runs too lean, itll cause hesitation and drivability problems. Any carburetor will be able to start and run but the tune might still need some adjustment.
I’d like to get a Holley 650 on your recommendation for a future carbureted LS swap. I know absolutely nothing about automobile carburetors. Is there a certain model of Holley 650 carburetor I should look for? New? Used? I know a bit about cleaning and rebuilding small engine carbs and that’s it. I know nothing about tuning a carb either. I guess I should have specified I will add a SS2 cam and some PAC 1218 springs. Probably on a 5.3 or 6.0
As you probably know, carb selection is much harder than just a cfm rating. Since you dont know too much about tuning, I recomend going with a 4150 vacuum secondary carb. I would avoid 4160 and double pumper carbs because they are harder to tune. The specs are usually listed online but something that comes with something similar to a 74/78 jet split should be really close out of the box reguardless of CFM
@@NightWrencher Thank you for the advice. I will look up the information to make sense of what you just said. I like learning new stuff. I like to learn from people like you who really understand and go into detail. I am enjoying your carburetor videos. Can’t wait for the new one to drop.
Hey bud, didn't see your comment. The summit 600 is an autolite design very similar to a holley. They use the same accel pumps, jets, secondary diaphragm and boosters. I've heard good things about them but I don't know how tunable they really are. For your engine I would suggest a 670 or 750 carb. a 750 if you don't want to tune it too much besides jets. a 670 you'll need to drill out the IFRs, rejet and get a higher number PV. A 750 you might just have to rejet. hope this helps
I feel weird because I love your advice but imma do a 750 on my lm7 but that’s only because imma pro charge it. But may I ask, for specifically what I’m doing, what do you think? With a forced air is single or duel better?
Bigger is better for forced air. Youll lose a little bit of low rpm drivability and gain a ton of power up top provided you run the correct blow through carb for your application
You gotta remember that the intake and cam dictate the power curve if the engine. Under boost it will follow the same cuve but the choke point becomes the carb so you need to go to the next size. With a cam and a procharger on a dual plane you can get good bottom end torque and the power will go all the way up the rpm from the cam and boost. Peak numbers will be down, sure, but if your drive a pretty heavy car or truck, the extra torque will help a ton.
Don't forget to keep an eye out for the next video if you want to win a free carburetor!
