In search for a mild performance upgrade...

[1966Coronet]

Will this combination give what i'm looking for? I wanna a nice idle-exhaust note, nice throttle response, from idle and rolling without breaking the bank.

So far i have acquire an Edelbrock Performer Series Intake Manifold (dual-plenum), Edelbrock Carburetor 650 cfm, Edelbrock Cam and Lifter kit with the following specs.

Cam Style
Hydraulic flat tappetBasic Operating RPM Range
1,200-5,000Intake Duration at 050 inch Lift
204Exhaust Duration at 050 inch Lift
214Duration at 050 inch Lift
204 int./214 exh.Advertised Intake Duration
262Advertised Exhaust Duration
272Advertised Duration
262 int./272 exh.

Without altering the lower end, will this give me what im looking for, im also planning on replacing the valve springs and valves.

Thanks for any feedback!

I am assuming a 318? This will be a nice little combo with good throttle response and should net you a nice little bump in power when combined with a free flowing dual exhaust. Be sure and upgrade the ignition if you have not done so already.

 

[1966Coronet]

yeah it is a completely stock 318 that came with the 4 door coronet. As far as ignition upgrade what are you suggesting? Should i get rid of the point set and go completely electronic ignition? And do you think that I should go ahead and change the timing gears?

Thanks for the reply...

1966Coronet,
If you are looking for a performance upgrade over stock I think it is the right move. Not too much but just enough. Add some headers and good dual exhaust with h-pipe you will be in business. Definately should wake it up.

I agree with Greg upgrade the ignition. If nothing else do the basic tune up replacement parts until you can upgrade to pertronics or Mopar performance stuff.

What gears do you have? Cars weight?

I used the next step up cam, 218 intake duration IIRC. Power started just a bit off idle. But it was in a Duster and a dead stock 318 with basic bolt on's besides the cam.

Points suck.
I would do a MoPar electronic distributor fired by a Chrome box. My MSD's always fail me. The few I did have that were good were very good for the car/engine power, mileage and quick starting abilty. But with my luck, if I do not have a back up box, I'm left stranded.

 

[Meep-Meep]

I'd say you are on the right track and I'll agree with the rest that say free up the exhaust, even if it's just adding 2-1/4" duals. Also put in a double roller timing chain since you'll have it apart.

For ignition the MoPar orange box kit is fine. I'm running the orange box on my 440 without issues. The main benefit will be a proper performance oriented distributor curve.

What gears do i have? Wow, i guess thats gonna be my next forum question. I dont really know. Since its my first project car, and my first classic Mopar.

 

[Meep-Meep]

Assuming the rear end hasn't been apart there should be a metal tag on one of the cover or third member bolts with the ratio stamped on it.

 

[shag766]

this is probably off the wall but wouldn't upgrading the heads while the motor is down for a cam change be the best and reasonably priced upgrade at this point. you can always put the headers and ignition to it after assembly with out tearing down again as your wallet can afford it. the double roller chain also while its down. the new ignition and exhaust cost will probably cover the head upgrade. i would do the gears last when you can afford it.

my .02 cents

 

[66 coronet]

Is this a 66 coronet 318 your talking about?? If so then it is a poly head engine and none of the stuff you say you have will fit.

 

[rumblefish360]

Considering he just said this is his first muscle/MoPar, great catch. Are Your valve covers straight or wavy on the bottom edge?

 

[shag766]

where did this end up. does he have the right parts or not. inquireing minds want to know.

 

[1966Coronet]

wow guys you guys now have really throw me to a wall here!!!! The parts might not fit! I wont be able to sleep tonight thinking about it. I just got back from Atlanta and havent had a chance to see your feedback, I dont want my neighbors to see me uncovering the car at 2 in the morning to check the valve covers, but they will sure see me at 6! Bitting my nails :icon_hang:!

So if the valve covers are wavy at the base Im screwed... can I just change the heads if thats the case?

 

[1966Coronet]

:hello2:Guys found this picture, I think its safe to say that the valve covers are straight

 

[1966Coronet]

Found also this remark in another thread... will revise it tomorrow. Im pasting it in case somebody needs it!

[66 coronet]

Sorry, but that is a poly head engine, I.ve got a car just like yours sitting in my driveway now. So now you can decide to build the polyhead or spring for an LA engine to drop all your goodies in.

 

[1966Coronet]

So being a polyhead means that no carb, no intake, no camshaft lifters will work?
Wow, ive been reading alot about the poly engines, they are great! But it seems like its gonna take alot of money to get to where i want to get it. I think im gonna go and look for an "la" engine. But im not going to get rid of this poly powerplant. No way jose!

 

[kb67mopar]

I vote build up the poly! I think they are a cool engine and I know it can be done.

I think he said this was bored and stroked to 396 ci...or somewhere around there.

 

[1966Coronet]

WOW that sure is a beauty... that looks awsome. But I have to take into consideration a mortgage, 2 kids, 2 dogs, and a wife that is already starting to hate the UPS guys for bringing me parts. jajjaaja. I sure like the rarity of the POLY and the all the potential that it has. Im gonna drop in another engine in the car, but im defenitaly keeping the POLY, just to play with it.


And for those wondering it is a POLY, the valvecovers are wavy on the outer edge.
