So i realize that, along with other reasons, I have not driven my 71 Challenger as much since installing a 408 stroker in it about 6 years ago or so.
My car is a 318 car originally and I am thinking of a few options:
a 318 with a bumped up cam to run a 4 barrel
a 340 built to average specs
or use my 360 block with all parts that I can salvage and go back to a "normal" crank with X heads
I am so done with Econo air ports and plan on hopefully running X heads or something similar from pre-71/72 era
I kind of just miss the simple cruise that I get out of my 68 D100 - 318 and sort of get tired of sitting there lumping at red lights. Of course its nice to step on it, but with todays gas prices never coming down, I feel that I'd be just as happy chillin along....
What do you guys think?
What cam did you put in your 408?? Everyone tries to push big cams in these strokers. What exhaust do you have.
I putt around town and run errands in my 416. Starts on one pump with a no choke double pumper, a single plane intake, and open element air cleaner. It's got a comp 274S cam. With a dual plane, 750 vac sec, and stock air cleaner it would be even quieter and smoother..
I've got 1500 miles on it since April.
Here's it idling: http://www.youtube.com/watch?v=-8QSTlvdqSs and

Maybe you can talk someone into a swap, your 408 and cash for a smaller motor.

Not me, I love my stock bore and stroke 340.
I put Edlebrock heads on it along with lighter 10.5-1 KB pistons and it runs like a stroker, I think. Compared to the 6 or so 340s that I have run before in this car.
It'll go in extreme conditions, hi in the mountains and in the desert heat. We drive it.

To the OP, you know what made my car reliable with the stock 5/16" fuel lines? Going back to a mechanical fuel pump. Got rid of all the racing fuel pump and filters and now my car run's and never Vapor locks. This was 10+ years ago when I was running straight race gas. Today with the ethanol fuel it would be even worse. Racing fuel pumps require large inlet sizes which a stock tank struggles with. Learn to tune the distrubuter with the carb and that makes a huge difference in drivability also. Even with a big cam most can be made street friendly. Keep the stroker and tune on it first. Good luck. Quote:

Yes, was there a couple weeks ago. We we're a little closer to heaven. 
My little old 340 went right up that huge azz mountain, I tuned for it.

The most popular engine we build is a 440, KB237's, stock iron heads with stock size plain valves, the SUMMIT 6401 hyd cam ( one of the best street grinds ever made), stock intake, stock stamped rockers--we polish it off with a well tuned distributor, well tuned carb and away it goes! Manifolds or cheap headers and you have an engine that has giant TQ, well over 400 HP and will run like the Ever Ready Bunny! It will MELT tires, tear second gear up and cruise to any spot in the USA with ease. Guys that have them LOVE them! I have built my fair share of big inch inch pump gas monsters and while impressive on the dyno and at the strip it is almost impossible to hook it to the street. The Mopar legend was made with nothing more than that.
My all time favorite is still a 340 4 speed A Body with some gear....so I understand where you are coming from.

Cool, went up that mountain several years ago on the train, my sister lives up in Florisant (she lives across from the Thunderbird) at 9500 ft. For a flatlander it's tough, really tough. Thanks for the memories.

I have 20,000 miles on my 408, with the comp cams .484 lift 108 lsa cam, 10 to 1, the car has 3.23 rear gear, pump gas diet,well over 100 1/4 mile runs, I would drive that car anywhere. Averages 1.80 60" time,if I put a gear vendors unit in it and it would get better mileage than my jeep liberty.

I'll get some specs together sometime soon. I appreciate all of the responses!! After all of this time I still have not memorized my cam specs...  I agree that it has alot to do with the converter and cam. I have a permanent exhaust leak too so the heads are 100& gone when I have time and money, I really need it broken down, checked and get everything documented. I honestly grabbed the block and heads, then the kit and never degreed the cam. I admit that something has to be mismatched. I sit at a red light and it wants to jump slightly even though it has a 2800 stall converter..... Runs great otherwise and has no heat, fuel issues. I probably come down from the 750 edelbrock carb as well. I like the option of working with what I have for financial purposes. I really need an "engine guy" to go over this puppy in the future and set me straight.  I am running 3:23 suregrip btw.
