318 to 400 transplant. Is it worth it?

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.

you know what you are right , they are like night and day ,,,,, have some fun with the 400 but ill tell you this you will never look back to the small block ever again once you go big , all your ganna wanna do is go bigger and bigger , next thing you know your ordering a stroker kit from 440source for that 400 and bam you have a 500 stroker with their alum heads and the cam setup , you will never ever look back to the small block stage with that kind of power

I'd use the low compression 400. Turbochargers and superchargers like low compression ratio engines. Be sensible with the boost and have plenty of power, fun, and reliability.

How is it a "turbo or blower" fits into a low budget? What is the absolute cheapest blower for a mopar- 4 5 6 grand?? Remind me to not inquire about low cost ideas here. In the old days you could take a GOOD running sound smogger (B/RB)and put a better cam, intake, carb and good dual exhaust and have a torquey mill on a budget. A 400 done this way is no match for a 1970 440 magnum but its leaps and bounds ahead of the 318 he has. Plus the 400 smogger holds major potential for future changes when money permits. For $200 he is getting all those nuisance parts youd have to hunt down. Having a driveshaft made or modified professionally is not expensive. Good tight 400 with a Comp Cams High energy cam, weiand action plus dual plane, vac secondary holley, cheap headers with dual exhaust and cheapie turbos would be a new world compared to a teen.

If it runs good and needs nothing.... $200 for a running motor is a good deal. Sell off your 318, hunt down the parts to change it over to a big block, and swap it in. Drive it, and build a 440 later if you want.

Personally I'd find a 360 and drop it into place. The money you save on a BB trans you could probably locate a running 360 or donor car/truck/van...

Just be careful... it's a slippery slope. My 318 was in really poor shape and somebody GAVE me a 360 Volare wagon. My weekend/low-buck swap spiraled WAAAAY out of control into a rebuilt motor and trans and over two years of time and saving.

And remember.... there is no shame in a Satellite. They all don't have to be turned into RR clones...
