Manley didn't do a very good marketing job with the 14279's IMO.....BTW Brandon at 440Source was also making a Mopar width 6.535 rod for the 511 crowd and a 6.76" for the 470 guys.
I'd rather build an run a 470 low deck than a 493 RB, especially in an A body bracket car, they'll make about the same power (the 470 at a few hundred RPM higher) and it's a bit lighter and more compact.
I agree if you're running a new rotating assembly a Chevy width crank makes sense.....But if you have a Forged 440 crank laying around for a 470 low deck (the 470 makes for a killer bracket motor) it was the best solution. Also if you had a 4.15 Mopar crank it can be offset to 4.25 or 4.30 with a 2.200 BBC journal.
With the economy turning down it might make good marketing sense to start making these pieces again.... lots of people have old cranks laying around and (given an economical option) might rather grind what they got then fork out for a new crank.
CBK, I thought you were running a standard stroke RB in the Haze??? If you were gonna offset grind a 440 crank somebody had a set of the Manleys in the Swap meet but for a Snail (turbo) motor I'd run the H beams and in your car I might opt for the larger Mopar journal anyway.....
