Never tried this before!

i just bought a '73 rust free dart for 2000 bucks in primer and needs painted. It has a 318 stroked to a 390 with heads intake cam headers with a stupid ford 9in. I'm currently stroking a 440 to about a 496 all the same fun stuff as the 318 minus the ford 9in (trying to find a dana 60 or a 8.75). Where do i start putting the big block in the car? Do i need a k-frame, special oil pan, headers, motor mounts, will it clear the factory steering linkage, or any body mods? Thanks for the help!

Before you go spend a wad on some overpriced aftermarket swap mounts, look around on this site and over on www.bigblockdart.com, where you'll find simple do-it-yourself modifications that will allow you to use slightly modified stock parts to achieve the same end.

The spool style V-8 ('73-up) k-frame that is currently in your car is a nice piece to start with and only requires a slight modification to the driver's side mount and the use of '73-'78 Big Block B, C, or R body spool type mounts.
For an oil pan, one from a '66-'73 fullsize, usually referreed to as a "187" pan is the one commonly used for this swap.
The stock steering linkage already on your car will clear a Big Block.

IMO, it's a darn sight better to figure things by modifying them yourself, than to call up "XYZ easy mounts" and just pay through the nose, when you could have learned something and done it cheaper.

But that's me. :p

Mark.
