Ive found out the 284 and 292 mopar cams need alot of stall and low gears for sure to get out of the hole. There was an article in a mopar mag a few years back of a 70 roadrunner that had the 284 mopar cam and was a dog, they swapped in a XE comp cam and it came alive and picked up HP. That doesn't come as a big surprise given Comp is a big advertiser there.  Kevin

Sooooooooo............
Car shreds tires.......change converter......... car is a mutt.........now it needs a different carb??
That must be an interesting trouble shooting chart. My thoughts exactly. If all you did was change the convertor and now it's a dog, get rid of that convertor.
I love the smell of Deer guts in the morning, it smells like... VICTORY!

I have damn near the same setup except I DO have the TRW six pack pistons which give more compression and I have the 284 installed 4 degrees advanced and a Mopar performance 2500 stall convertor. I have 323 gears. stock 452 heads and stock intake with a modified TQ. This is in my 1972 dart. It will burn the tires off until I let out of it!! My only complaint is that it quits pulling after 5500 rpm. I need more flow at high rpm! I want some better heads! The advanced cam timing is taking away the top end, change that first.

Kevin well my personal experience I went from the mopar 292 cam to a XE294 in a low compression 440 and my ET dropped and the drivability improved and I get no check or funds from Comp cams for saying this statement.

As is the case with the magazine reference, without seeing the rest of the cam specs/ICL we could speculate all day on why that happened. If the MP cam in the magazine was installed say 4 deg retarded either deliberately or because whoever just lined up the dots and the Comp was dialed in properly and installed 4 deg advanced, it should come as no surprise that "it came alive" especially if it was a low compression engine and the cam specs are similar ie same lift and duration @.050, overlap LSA etc. Kevin

We could speculate all day on comp being an advertiser there and what really happened as you said.

...How about you check and see how high you can get the engine against the converter ? Warm it up thoroughly then mash the brakes and then see how high the engine will go in first gear. A real 340 converter in your package should get you around 2600 to 2800 stall. If not then likely your stator overrunning clutch is failed in the converter. Or it's not a real 340 converter. A failed stator ORC will run down the road fine but make the car lazy off the line.... I'm waiting for the results of the stall test.

Don't most stock iron heads drop off after 5500 rpms anyway? Maybe not a cam problem in his case.
