408 mopar stroker intake/carb

Hello,

What is the best carb and intake manifold for a 408 mopar stroker? I was thinking an 750 or 850. This is strictly for street.

Thank You.

a 750 or 850 is great.The 750 is good for a mild build,step up to the 850 anytime after you are making 450 plus hp.
not sure what the best intake is for your application? maybe describe a little about the build and car? Paintedjester is a very good Mopar guy,and others

Ty for the replies.

727 tranny, 3500 stall, 3.73 gears

Apparently the carb that's on it now is a 600 edel. With 750 quadra jets. Is this enough for the beast ? It also had a 318/360 edel intake. It's around 400 hp or so.

I'd use a performer rpm and a 750 holley vac secondary. Exactly what I used on a 360 years ago.

Ok sweet. I have a 318/360 performer. So is my 600 with 750 jets holding my engine back ? Will I see a difference jumping to the 750? Is a dp worth it? Or just get a one with secondary vacuums.

Do you have a performer or a performer rpm? Going to a 750 dp or vac might not make much difference.

Edelbrock RPM #7176 intake and either 750 or 850. If auto with under 3000 stall converter, use vacuum secondaries for best results. If stick or 3000+, use double pumper.

So it's just like a stock intake for a stock motor. With your mods you need a better flowing intake and carb like the performer rpm and a 750 or 850 vac secondary like techinspector suggests.

So is my 600 with 750 quadra jets too small for my 408 stroker? Is 850 too much for some street fun? Which 750 model carb should I get?


Thank u

Yes your 600 and your intake are too small. And you're right about being around 400 hp. Actually a lot less than you think. Around like in the 250 hp area with the carb and intake you have now. You gotta make it breath if you want to get all the potential out of your motor.

Which 750 should I get ? I got the intake chosen already. Is 850 too big?

I personally only use double pumper carbs.There are plenty of good carbs,but my main objective is good throttle response and lots of power.
I've used thermo quads with success too.
brand new HP series,custom build for your engine is around $650.oo.Bolt it on and spin the tires(a lot)
