I have a 69 Dart with a 340. I want to add a new cam with a lot of lope. Can I do this without much additional work to the engine, just adding the cam, rockers ect. It's pretty much street driven only. Suggestions? Does the motor need to come out to do this?
 
my thoughts of lopey cams with chop aside...

motor doesn't need to come out. you may or may not need to upgrade your valve springs.

counter-point: you could roll the timing back and tune the carb to give it that gugg-a-dugg-a-da sound for free. it'd probably run about as well as "cam that sounds cool" and is a total mismatch for the set up.
 
In a lo-compression model; 318-Whiplash, or small ThumpR.
Yeah, I know it's a 69 car. but does anybody actually think that after 55 years the guts are still stock. Com'on most of these were blown up within the warranty period already.

But be advised that as soon as you get the revs off idle, they smooth right out, and then the jig is up.

Like JYHero said, just idle the stocker down, retard the timing a lil, richen it up, and chug-a-lug on down thru the DQ drivethru.

Hughes Whiplash. But just know "whatever" cam you choose must have the matching valve springs installed.
 
Hopefully the retard the timing crack was a joke because it won't pull a greasy string outta a cat's *** if you do that.

it'll make just enough power to pull a sick ***** off a piss pot. and honestly, if you're buying a cam based on "it sounding cool" and cruising for burgers do you need much more than that?

Thing is, the Whiplash and Thumpr cams, while made to sound good, can run really well as long as the engine is tuned.

begrudgingly, i'll accept that.

howevah, the caveat remains: as long as the engine is tuned.

and therein lies the turn of the worm. if you can tune, why would you run one of those aside from it being the easy button? more better-er stuff abounds.

I know that, you know that. Most everybody else here knows that. But that's what the OP asked for.

How about running a compression test for us and let us know what you got to start with. What do you know about your engine to start with and what gears does the car have?
