I'm looking for info on big block options for my 66 Sport Fury auto. At first, I researched some easy(er) upgrades on the 318 such as a intake, 4bbl, cam, headers etc. Pricy. I think I can find a drop in motor for the costs of those things. I have a buddy with a 71 413 in a Winnebago that runs, so I thought that an option. Someone said a 383 or 400 would be the best options, as a 413 is going to be a lot of work to get to fit, i.e. water pump, oil pan, exhaust, other parts that dont fit, etc. Id like to find something to change out motor mounts, radiator and drop right in with minimal issues. all opinions and recommendations appreciated.

I don't think you'll have any problem getting an RB type (413, 426, 440) into a C-body....those engine compartments are huge.

It'd be where I went first. The Poly 318, while I love it, is not easy to hop up.

There's no replacement for displacement. BUT, a 413 is just 5 cubic inches bigger than a stroker 360, a 408. Now a stroker 413 can be anything from 472 cubic inches on up.

Choices, choices!

as long as the 413 is not a 8 bolt crank HD truck engine with its own specific WP/housing/exhaust manifolds...it may be a drop in with a BB727.

some of those 413s are same as a car 413 that can be made right into a 426 wedge engine.

ID what your buddy has for sure before you decide to pass on it.

I am going to get the one I found..every one said it was the HD truck 413...NOT! 250$ and coming home with me.

If the 413 is in good shape & likely the price is right I'd jump on it. The pan/pickup/water pump housings are an easy change as needed & cheap. I would swap the manifolds to 68-70 HP items. in that big boat you need torque (cubes) & the 413 will get you up & running fast(er)/cheaper so you can cruise this summer whiel you build a stroker 440

The 413 can be a torquey little guy but don't plan on rebuilding it in the future unless you enjoy spending money. The pistons are unobtanium and must be custom made in most cases.

Have you thought about stroking the poly? There's quite a bit of info out there on that. http://www.moparmusclemagazine.com/howto/mopp_0110_how_to_give_a_318_poly_engine_more_power/ is one such article.

I don't want to get too deep into the guts on anything I buy, including the 318 that's in it. Id like to pull the 318 & Tranny and would like something I can drop into place w/ mount and radiotor changes. The motor and tranny are still in the Winnebago, so no idea on the crank. Just wanting a good big block that I can do some stuff to on the top end as I go along.

A '71 413 shortblock should drop right in, you may have to scrounge passengercar heads, manifolds, waterpump asembly, etc. Or maybe not. It's a Mopar, never say never.

There are still tons of RB motors out there in motorhomes. The only problem is you usuallyhave to take the whole MH, or else the guy thinks the engine is something special. But your deal sounds like a winner. Go for it.

Some MHs had a parking brake mounted on the transmission tail shaft. If so, a donor trans will need to be found.

You know, that's true. But the MH 727 is a keeper, you have to change the output shaft and tailhousing. The one that's in the car right now may work, John Kunkel will know.....

I appreciate all the help. Thats good info to know. I have a different friend that has a ton of Bb parts, and motors, but all need rebuilt, mainly 383 stuff. A lot of the stuff would interchange (waterpump, oil pan etc) w the 413 wouldnt it?
Also, to clarify,if the 413 tranny has the ebrake mount, and other shaft, it can be swapped out?

I have owned many 413 s and some were motor home engines , some truck engines and standard car engines . I believe they may have had different cams and heads as the truck engines could not rev like the car engines but could lug for ever.
save the cam gears on the truck engine as there is no timing chain but not sure if the cam gear will go into a standard housing.
A friends dad had one of those old dodge motorhomes circa 66 all fiberglass and no corners. It had badge on the side about 4' sq. that said 413 Super High performance.
So I pulled the engine cover and saw the biggest set of manifolds I have ever seen . It had a monster Holley carb on it too.
You grab the RB and there are lots of B and RB parts that will fit .
Good Luck with it .

A truck or RV engine is adding complications for no reason, the exhaust may or may not work the oilpan, and pickup will need to be swapped out with the correct c-body pan, the waterpump is likely to be a passenger side inlet which causes radiator fitment difficulties.

There are bunches of 66-73 c-bodies with running 383's and 440's that can be had for 800 to 1600 and you will have all the parts, engine, trans, plus lots of clips and hardware and other parts that were used trough the years on these cars , And with the right parts car you can get the brake system out for yourself or sell to others wanting to upgrade brakes.

Well, it sounds like the 413 idea is going to be more trouble than its worth. I may buy the thing and pull the motor and tranny anyway, as it sounds like its worth something. Looking for 400,383,440,what ramifications do the body types a, b, c mean in terms of motor mount/tranny drop in on my 66? What about model year?
Thanks for the help.

Any 66-73 Big block B or C body the engine and trans and radiator will be a easy swap into your 66 Fury. Its not likely to find a B-Body big block car without paying a premium.

Look for 66-73 C body 4 door or wagon as a donor

get it as complete and running if possible, it will save you time and money in the long run, My brother and I have bought 4 over the past year and we are in So. Florida which is limited in square miles of where these cars are.

look here for cars and parts as well as the local craigslist.

a quick look and I found this, http://ocala.craigslist.org/cto/4465628927.html

i been reading your posts over the last week or so (welcome aboard byt the way ) and i don't see or remember what you budget for this project is. i'm gonna guess and say you're like most of us and say it's not alot of $$. that said i'm gonna pony up with the 383-400 engine group. easy to find, make decent street power on a lowish budget and should pop right in.

dont rule out the MH RB engines. my 78 lopo 440 from a MH and 78,000 miles on it really woke up my 88 swb truck.

shave 40 foot of MH, add a RPM intake/q-jet/duels/3.91sg and it is a killer street cruzer.

the 413 I am looking to get has wedge heads and looks just like a car engine, even has headers on it (not the big truck manifolds specific to HD/IND-413s)

not sure what wedge heads but looks about like my MH 440 does.

my trans was a short shaft bolt on yoke, bolted right in the stock location but I had to build a drive shaft with a slip yoke.

I'm with SFT, the MH engine is worth using.

R.

Okay, weve been talking about the mh 413. A couple of new options have come up:
1. a 440 from a mh. Does this pose the same problems as the mh 413?
2. A mid to late '70s stock 400 from a cordoba. Its in a Coronet. He wants to keep the pulleys, and distributor. Is this later model 400 a decent option?
Thanks for the input!
