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 think you'll find that the 400 lacks the power you seek. For $200 if it has all the big block brackets accesories etc it will be worth far more than $200 in parts GRAB IT. The big block trans is different, plan on a driveshaft change too
You always can sell the 400 to someone wanting to build a 451, or build one yourself later

With gas prices, I think I would redo the 318.
maybe a nice cam to give it a little thump.
Sounds great and great gas mileage is a plus in these days.

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 swaped a 318 to a 69 RR383HP in a 67 satellit and it was worth it to me, it cost me a total of 1800 bucks and that was with selling the 318 for 600 bucks because it only had 4000 miles (reman) BUT the Satellite is a bigger car. I would put a 360 in because of weight issues and the potential overheating. Either way it will cost you some cash but with the SB you can keep your trannie

i picked up a 73 413 for $200 and its a low compression motor ,, but ive already put 906 heads eddy rpm cam and a tm7 intake , that motor sounds killer .but yeah if i was you i would go out and find 360 or just pay more for a 440 setup .if you dont already have the big block setup and not willing to spend the money and dont do it , it will be a long journy and money blowing setup, i know ive done it twice .

????????????, what you wanna know

Show me a pic of a 1973 dated 413 please

I would say it's a good deal. Like was said even if it is a stock low comp 400 you can change that later. I myself like th bigblock torque in heavy a B-body. You can always stroke it later or just build the stock stroke 400. My son's Dart weighs almost 3600 with him and a full tank of gas and his stock stroke 400 has run 11.40's in his stock body Dart so yes you can make a stock stroke 400 run good. His is nothing fancy as the Eddy heads are his best part on his stock stroke 400. Ron

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.

1973 was the last year of the motorhome 413 so they made 413's in 1973

THAT is a 1973 motorhome 413 in a 1977 Road Runner. I know because I bought it in 1979 and put it together.

they did , but 413 and 400 were in the motorhomes and big truck, they have those water pumper heads on them , if you ill git it later , tripped me out to when i got it last week. but yeah the 413 was around in the 70s just a low compression motor , the best way to do some resurce is on 440 source orig parts http://www.440source.com/timingcovers.htm check out the timing cover on the bottom http://www.440source.com/wpumphousings.htm the huge water pump housing in their is in the 413 to

that is a 413 with te water pump housing and head replaced

1977 was the last year of the 413

i say go for it. b bodies and b motors go together like pb and jelly. i think in 72 all the v8 k-members are the same except for hemis so all you will need is mounts, bb tranny and driveshaft...and prob a radiator.if you plan on putting the engine in as is, at least put a new timing chain set in. sure the compression may be less than 8:1 but a stock 400 with 4v and a mild cam will be night and day compared to the 318 you have now. put it in, have fun and save your money to build a killer motor for later.
