SCREW IT!!! I'm not selling the Chally~~Sell some guns, upgrade the motor

[Glennster]

NEW game plan, SCREW IT, I'm not selling the Chally. Times are tough, cash is tight, but I need to keep the faith!!!!!!!!!
I'll sell one of my M1A's and one of my AR-15's, put a little cash in my pocket and upgrade the carburetor and exhaust system on the old Challenger.
BTW - I've got a 1970, 318 - Bone stock.......
Here's where I need some direction. I just scored a nice Edelbrock 2176 Intake, so I need to get a Carb. I hear that a 600CFM is the way to go, I like to keep it simple so I'll go with a manual choke.
WHICH carburetor should I get? Holley or Edelbrock? Does it really matter?

Next, Headers. I don't want something that's going to look like a rusty mess in a few months. What is a good quality header for the 318? Should I go with Stainless Steel?

Finally, Exhaust System and Mufflers. What do I do here?

I'm not trying to build a drag car, I just want a smooth running motor with a good sound.....
Thanks for your suggestions!!

Sell the AR-15 KEEP the M1A. I love them!

[Glennster]

I'll keep one M1A (w/ Scope), they are great! Four AR's is too many, I'll sell one................
Back to the thread!!!
Holley vs. Edelbrock  - does it matter?
Headers?
Pipes?
Mufflers?

[bb71challenger]

Great news! I am glad you are not selling it. I have only tried one Edelbrock and didnt have much luck with it. It always ran rich. It could be that my ignition was weak though but I have heard from others that they run rich. I have had better luck with Holley and really like the 750 vacuum secondary that I made with a proform main body.

I hate Eddy carbs tough to adjust if it is even possible , I would run a 570 Holley street avenger or a 1850 600
 Headers there are only 3 to use TTi , Dougs or the Hooker 5115

[RaptorF229]

in todays times now is the best time to sell your extra ARs I'm buiilding one in ca and prices are horrible or out of stock everywhere.

[Glennster]

Chryco,
 Are any of those Stainless?
Which one look good long term?
Thanks for the input!

for exhaust I'm looking at Pypes for most bang for the buck...Stainless with X-pipe for 303 at Summit http://store.summitracing.com/partdetail.asp?autofilter=1&part=PYE%2DSME10V&N=700+401344+4294908110+4294908104+115&autoview=sku

[Chryco Psycho]

TTi & Dougs are ceramic coated & will hold up well to deterioration

IMo, if you simply want sound, I'd use the Edelbrock 650 carb, and keep the manifolds. There is little sense in spending big coin for a result you don't need. Have a good dual system custom bent, use 2.5" pipe, and good mufflers, and you'll have an engine most people see as a 340, and a good sound without spending all the extra hundreds.

[Glennster]

Great suggestion ! ! !
I was looking at some ceramic coated headers......a little over $300
I've actually got the original stock single exhaust on the car, I'll do as you suggest and run some dual pipes off the stock manifolds.
I'm going with some Flowmaster mufflers, should sound sweet for car that almost needs a slow moving vehicle sign!!!!
THANKS!!!!

Headers are always the single best thing you can do to improve performance, but it's up to you what's most important. The best carb known to man for your engine will not deliver the performance improvement a good exhaust with headers will, even cheap ones on a car with stock manifolds.

[Glennster]

Oh crap....
Now I'm second guessing myself..................
Headers help that much?

I would advise going that way if you had put a bigger cam in to go with a better carb. Headers might mean another 10% in horsepower gain. It's really up to you. With a 318, what do you want to accomplish? Stay stock and be a nice cruiser, or are you wanting to surprise people at red lights? From experience, headers are a pain. If you have no interest in boosting horse power, then don't go that way(towards headers).

I don't know about fitment but an article comparing exhaust manifolds & headers just changing to 360 manifolds, a low buck junkyard item, will gain power. 


Here's the chart
