i just got back from looking at the engine. I got these numbers 3.28.74
3830930 440-6 and on the cylinder head 3769902. the guy said it came out of a chrysler new yorker. i tired to check around for these engine code 3830930 but it didnt seem to match up with any of the codes on quite a few charts i checked online. if u have any info on this gimme a shout. thanks

If you're going to use the 440 the first thing you're going to need to do is get the compression up to 10 to 1. In this range you've got a large selection of cams to choose from depending on what you're building it for. The other problem is that year of engine has probably got a cast iron crank in it which will limit how many ponies you can build to before going forged. First thing Id do is drop the oil pan and post the crank casting number. Also those 902 heads are a good starting point but you'll probably want new valves springs and retainers installed. Again, figure out what you can afford then how far you want to go and we can help ya out. Or better yet take a look in this link http://www.moparts.com/Tech/Archive/bb/22.html at the crank shaft vibration dampener and tell us what one is yours
