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.
