Hi guys,Need some input on cam,intake and carb choices I have for a 360 build for my wifes duster.All she wants is a "nice sounding mopar and a lil pep to intimidate the mustangs and the import rice cars"..Her words not mine lol.

Some info:
1977 360 rebuilt and bored .30 over
915 "j" heads with 1.88/1.60's
Stock converter and trans
Headman Headers with 2.5 full exhaust with a X-pipe.
8 3/4 rear with 3.23 gears and sure-grip

I was thinking this 600cfm carb from quick fuel..Will 600cfm be enough for street.i don't think the car will see more than 5k rpm's.

For intake I was thinking a Weiand Stealth Intake since basic op range is idel-6800

and for cam I have a brand new mopar purple 340 spec cam in the garge to replace the stock 2bbl .410 lift cam.

Any input would be appreciated..Thanks guys.
 
Comp XE268
Edelbrock 650 Thunder Series
Edelbrock RPM or Air Gap
I think she will be Very happy with the sound and Performance.
That 340 can would run well to,but I like the Comp.
 
You did not list compression so I assume stock.
The stelth intake has a smaller intake port designed for a 318, but will actually give decent torgue.
Look real hard at using this carb, it will start and idle smooth at -10 degrees, and not boil at 95+

If you have not installed the cam, consider returning it.
 
I'd do a 650 CFM carb
I would not use that purple cam. The 114 spec is going to give it a smooth idle. If she wants a smooth idle, then fine, go with it. The upgraded 340 cam with a 110 spec has that muscle car sound.

The intake is good, carb maker is good, everything looks good.
 
Nothing wrong with your initial thoughts at all.

If I was to tweak it, as mentioned earlier, i like the 650AVS style carb & the XE262 cam.

ok. Guess I can put the purple cam into a dd 318.
 
If she wants something simple to actually HAUL *** with what you have, tat 340 cam is tough to beat. Ask her if she would rather it sound good or get the job done. You already HAVE just about the perfect cam for it like it is. It will sound good, it will just idle some what smooth, but it will not sound like a stock 360. That 340 cam will really pull like a ***** in heat. It's up to you, but I'll be damned if I would spend money I didn't need to if I already had that cam. It's a good one.
 
I agree with RRR on that. That was the message I was trying to convey.
It will just idle smoothly vs. the muscle chopping idle.
 
To the OP.

The carb looks ok. 600cfm holley style should work well for her. The cam is ok as well. however I would go with the performer RPm air gap intake.

I'd be concerned with a few things.
-low compression
-stock stall
-tall gears
 
You could run that voodoo cam or the one a step down. You don't have a lot of static compression with those pistons. The Voodoo cams work very well! Rocker arm and spring pressure issues start to pop up with the cams sometimes.

Intake, even a Performer 318/360 would run great on that with a 1" open spacer. You could save some scratch buying a $80-100 intake vs whatever and RPM/LD340/Air Gap would cost.
 
If the car has power brakes I would keep the cam with the one you have..You dont want an open plenium intake either they are not a good around town intake they are more for mid range and up....As far as sound if its got headers or not with dual exhaust and flowmaster 44s it will sound good..If you want it loud then use the 40 series but it might have droaning issues...Bill
 
Allot of good sugestions. But there is nothing wrong with your original plan, especially if you are on a budget. If you want to step it up a little you could put in a 2000-2300 stall converter. That cam will have a little lope at idle and great throttle response. You can probably get away with your current valve springs also. Good luck with your build.
 
I'm running the 274extrems comp cam. .30 over 360 eddy heads and intake. [ame]http://static.photobucket.com/player.swf?file=http://vid1104.photobucket.com/albums/h336/bamamopar/225.mp4[/ame]
 
68 HEMI GTS, that sig pic is huge and screwing my viewing up! YIKES brother, can ya scale it down?

Agreed, with the flow nujmbers comming out of the dual planes it really isn't worth sacrificing any street manners for that tiny bit extra.

flowmasters drone and under acelleration sound rappy adn tinny. SOund great at an idle though.

With a quality convertor you could run a 3000 stall easy. Your wife would never even know it was in there. My car has a 3500 stall and my wife drives it. It runs like a normal car.
 
actually the stock heads are going to be a bottle neck. you are opening up the exhaust, the carb, the intake, but your flow will remain just the same through the heads. you should see if you can find a decent price set of heads with 2.02 intake valves somewhere. new is pricey but maybe you can find a set if you post in the wanted section. you never know someone might have some sitting in their garage taking up space. also check with your local machine shop sometimes they have leftover/abandoned parts.
 
It will be a strong engine with stock sized valves...they want low end bigger valves will make it cost more and not be cost effective
 
here's another vote for the XE268 cam..
I'm running the XE268 on my 360 (stock compression), along with Eddy Performer 600 carb, Performer intake, electronic ignition/MSD 6AL, 3.55 gears.. very snappy throttle response, nice idle, power brakes work great. Here's a few short clips where you can hear how it sounds

haha when i built my 340 i found a set of 2.02 X heads in the paper for $50 bucks. took them over to the machine shop to be dipped and checked, they were good to go. used the new springs for my new cam, i lapped the valves myself. i found that to be pretty friggin cost effective.
