went to a junk yard today, found a couple 440's for my road runner. i was wondering, do the motor home 440's come with a steel crank from the factory? the ones i was looking at both had electronic ignition so i would assume they were a later 70's model. any idea where i could find specs on them? also, while i was there a i found an early 60's winnebago with a 413 in it. any idea if those are worth anything? it had really tall heads on it, and the water pump was tall as well and it bolted to the heads as well as the front of the block. are those heads worth anything as far as performance?
any help would be great, or if anyone knows where i can find info on these things.
