How easy to get 500 horsepower w/ stock stroke 440?

I was at work on my lunch break I wanted to make a post to help get me thinking. I did do a search and that one didn't come up. I may have been to specific in my search. But now that I see it I do remember reading it before a week ago or so.

Anyways I can use that as a idea of what I need. But since 500 horsepower is so easy I might get a little greedy and want more. 530 horsepower would get me close to the same power-to-weight ratio as the Hellcat Challenger.

I had the idea to modernize the 440. I want to fuel inject it. Then I read about the articles that they are doing just that in Mopar Action Magazine. So coil on plug has me thinking now to.

I don't want to stroke it, I would like to keep the cubic inches down to help with fuel economy. Not expecting amazing MPG, but I am keeping that in mind so can pass a gas station every now and then. And will be using 3.23 rear gears.

What I have is a 1978 stock short block, so its has a cast crank. Needs to be bored out, It has been sitting in the garage for over 10 years, and there is a coating of rust on the bores and the decks.

Would like to use aluminum heads, hydraulic roller cam, HD stamped steel rockers (lightweight), 0 deck the block for quench, around 10.0:1 compression.

Should I recondition the stock rods or get new ones? Will the factory cast crank survive?

I would buy some new rods(and have them checked)for piece of mind.The cast crank can easily handle the power you are looking for but it would be easier to balance with a steel crank and no need for a weighted flexplate to run a neutral balance converter.

Good aluminum heads(ported a plus as airflow will make everything easier) and a small/medium hyd roller should get you your goal easily with better driveability and less octane requirement.10.00-1 is fine and consider some roller rockers as well.A good dual plane (rpm) intake and a minimum of 750 carb will get you there with room to spare.
