It's a trade off. All that duration is letting alot of this engines static compression escape.This becomes lee's of an issue as RPM increases. In a hemi, I say go for it. In a wedge motor,you are probably doing less good than you think.Unless you got some o them max wedge heads with intake ports you can stick your hand in.
@@christophermix6845 actually it is. The lope results from both valves being open for so long that the exhaust contaminated the engines intake charge. This leads too uneven mixture and distribution resulting in some cylinders not getting a suitable mixture to fire. At high revs and thus high port velocities,the clean charge is swept into the chambers and most contaminants are likewise swept out.So the engine smooths out.
@@davisjohnson5688 no, its not. Short/Long block are a reference to crate motors that aren't fully assembled. A short block is just a block with a rotating assembly. A long block is a short nock with heads and valve train and a cam installed with a timing set. A Big Block is a motor with a physically big block, and a small block is a motor with a physically small block. Like a 302, or a 305, or a 318, vs a 440, 454, or 460. A "Long block" is in fact not the same as a big block.
Love it. My first real car was a 68 Plymouth GTX, sunfire yellow white interrior. Went sideways on me out of the used car lot I bought it from in June 1970. The dealer had bought it from a soldier headed to Vietnam. $2100. That was a lot of $ for a poor Texas kid in 1970. Did a lot of red light street racing in that car. Only ever got beat, not by much either, a 70 Hemi Cuda. Traded it in for a 1973 Pontiac Grandprix when I got out of college. Got $800 in trade for it. Young and dumb😂 Miss that car to this day.
What a wicked car, I love the sound of that exhaust! Happy to see the older dart demons getting some recognition today since everyone I talk to at work seems more interested in the 2018 Challenger Demon. I also noticed a familiar sticker on the left rear side of the car as it pulled in, is that a real Mr. Norm car? that's one special ride either way!
I had a 72 they only made them in 71 and 72 we put a stroked 360 4spd in it funnest car I ever owned and the most compliments of its rarity nothing like mopar power
Thanks! It was Idling about 800rpm at the time if I remember correctly. I am very happy with the cam. Had a Edelbrock torquer 440 intake and 750 holley. Now have a tunnel ram and dual 660 holleys for next summer.
@@tetanustv6258 Thanks for the reply! That is awesome. 800 sounds about right for what I'm thinking too. And I like the intake and carb setup you're talking about. I was hoping the torque curve from that cam will be good too. Hopefully will have my motor in and going come spring time!
@@TheBugMan89 Best of Luck. I am very happy with my set up. I am changing to a 3000 stall and possibly swapping the 3.23 for 3.91 this winter. I have to rebuild the carbs and fire it with the tunnel ram yet too.
@@tetanustv6258 Thank you! Not sure what stall I'm going with but don't want a really high one. What did you start out with? I also have a 3.91 gear I'm thinking of using. Because why not, right? Haha
@@TheBugMan89 I currently have a stock stall and 3.23 sure grip. It surges and pulls when at a stop sign a bit. It didn't before the cam swap. I think the stall will really wake it up and it is just on the shelf in the garage. I also have the 3.91s but also want to be able to highway cruise some so I am a tad reluctant to go that deep right away.
Sounds great! but I gotta ask, is there a full exhaust on the car? it has that open headers sound also, how are the brakes? I'm interested in this cam for my 440 but worried the brakes may not work too great Thanks.
Thanks! sure sounds tough not having power brakes/steering is a good thing they (Hughes) do say a Vacuum pump may be needed when using their whiplash cam sweet Demon!
It is really nice having manual steering and brakes with no worries for vacuum. Here is a link to the video with the Magnaflow mufflers installed....ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--G4Tb9RF5Mc.html
Comp cams cam thumper, mutha thumper and big mutha thumper is great for naturally aspirated, power and sound. For more power and sound I had the big mutha thumper ground on a tighter lobe lobe separation. The piston to valve clearance gets tighter actually interference. Needs valve reliefs clearanced or deeper valve pocket pistons.
Had a 1968 coronet rt same motor and sound! If i was lucky i got 8 to 10 miles per gallon? It was my favorite car wish i still had it. I got restored and now lives up in canada
At that time, yes. I just put the cam in, it wasn't tuned well as there was carb issue. It was one of the first drives down the road in 34 years. I have a few newer videos of the car now
Awesome, I see the Mr Norms Sport Club/Dyno sticker in the window too, very rad car. My whiplash came just showed up for my 440 build going in a 69 Dart.
@@jasonhawkins808 I really like my Whiplash. Yes the Mr Norms decal. This is a true Mr Norms GSS Demon. My dad bought it new at Grand Spaulding Dodge Oct 10, 1971. He raced it for 10 years and sold it. I found it in 2018. Had dad with me when I bought it back too!
Drives me crazy to see everyone comment about the lope. Shows the lack of intelligence into the subject of cam specifications, compression and so on. Don't get me wrong, love myself a large camshaft. But... idling at 400 rpm, with a super slow lope just shows you've got more noise than go. Theres a reason most very fast N/A engines will have a fast paced, racy idle. This sounds like another run of the mill off the shelf camshaft with low lift, super high duration and an LSA designed to be more noisy than anything. To each his own... But i'll stick to something that actually has the ass to back up that noise.
Feel free to add a link to some of your cars. This was literally moments after a cam change and shortly after 34 years in storage. Lots of bugs have been sorted. There are a couple of my videos of the exact idle you refer to. This was a single Holley with issues. Now it has been remedied.
Nah, this video is several years old. Watch kne of my newer ones. More car now and the last 2 years have driven it a 12 hour round trip to Mopars in the Park. 13-15 mpg. With a gearing change. That drive is expensive with these prices today. I wish we still had the prices that were in this video.
Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station fuel pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spares will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called "Abgasbspaßung" :-((
They don’t understand that electrics actually cause more pollution. Where does power come from? Fuel. (typically nuclear) where do batteries come from? That’s right, incredibly toxic mines. How does the toxic material get transported to the factories? Yep, hundreds of massive diesel trucks crossing countries, and potentially massive guzzling boats. What happens if they set on fire? Oh yeah, lots of pollution. Infact, I split a button battery *outside* and the smell persisted for a month. Imagine what thousands of AA batteries could do. Also, the more electric cars, the more power plants made. And you guessed it, that means even more pollution. There’s even more to it, but I seriously can’t be bothered.
Just having a little fun. Played with carb after that. Needle under squirter was sticking. Had just beike cam in, literally right before this and had 0 miles on car since 1984. Playing it safe. Thanks though
Sorry for wasting such a large portion of your life. We had just got it running and driving after 30+ years. Car has changed much since then. Thanks for watching
Thanks for watching. This was years ago when the cam was installed approximately 10 minutes before this. Also, the car had been sitting for 34 years and had only been around the block a few times at most. No go was by design
