Recently bought 72 satellite sebring with a tired 318. Was hoping to find 440 to make roadrunner clone. Found a 400 complete and running out of a 72 newport with 65K. The guy is asking $200. Want to keep this a low budget project. Should I jump on the 400 or wait for 440? Need to change trans if going from 318 to 400 correct? Anything else?
Thanks!!

I would use a 360 before a 400. You can get 360s at the junk yard for $60-120. And other than the driver side mount and converter (or flywheel) balance every thing else off the 318 will work.

I think you'll find that the 400 lacks the power you seek.
Yeah, and the only 440 he's likely to find that could be dropped right in is going to be a low compression era 70's 440, which comming from experience is no ground pounder in bone stock form either.
If I had to do it again, instead of converting from 318 -> 440, I think I would build a turbo or supercharged 318 instead. Either that or find a 80's+ 318/360 with a factory roller cam and use that as a basis for a stroker build. But I know the OP wants to keep the budget down. I guess it really depends what your long-term goals are if you have them.
Just remember, bare minimum if you buy your big block motor/trans you will need a shorter driveshaft as well as either a big block K frame or the engine-swaps.com conversion mounts.
But if you want to drop in the big block, run it in stock form at first and slowly start throwing parts at it like an intake, headers, very mild cam, etc over the next couple years, the 400 is a good candidate. For the price, just deal with the 40 less cubes of the 400 and move on. 400 will be a little easier to work on under the hood because it is a little bit smaller than a 440. Slowly over time throw your mods at the 400(but keep it very mild so long as you are running the stock low compression 400 pistons) and slap a 383 pie tin on it and call it a day. If you ever decide to rebuild, some say the 400 is a better block for a stroker build than the 440 if you ever decide you really want to get some cubes out of it.

Not to rob the thread, but I think what he is saying is that they stopped making 413's well before 1973.

build up a 360. if you can get a solid low compression motor...supercharge it. use a a/c style belt clutch and you can cruise for economy or burn the tires off the rims. the best part is you can get away with all the smogger era gear.
Not "low budget." If you want to keep it cheap (I know I'l get for this), stroke your 318. Read the thread a page over titled 390 Cordoba (or something close to that).
