361 engine

[PwrWgnDrvr]

I have a 361 that was transplanted into a 66 D300 with a 4-speed and hydro clutch bell.
Is this BB bell, flywheel and starter the same as was used with the 383, 413 and 440?
It also has a factory 4v manifold which I was told is extremely rare and hard to find.
I may offer these parts for sale and would appreciate any info on interchange and current market values.

Doesn't the 361 have an extended crank flange compared to the 383 and 440? That bell ( if it's like one I have) has a solid front that puts the flywheel further back. And the intake is the same as any 'B' or no?
DC has a picture: http://www.jobrated.com/-bellhousing-id.html
The 361 and some truck 413's have the extended crank flange, the setup is apparently particular to that crank.

The 361 and 383 are basically the same engine so the 361 manifold is not rare. But the 361 was used in the 1950s and if this is an early production engine, pretty sure there is something funky about the crankshaft. 8 bolt vs 6 or something like that.

This is a stock truck 361, which were available in swepts and are included in the FSM. It has the truck style industrial heads and exhaust manifolds. The FSM engine service section lists 361 and 413 together.

Good question. When I put the 400 BB in my 70 D500 I used a bell housing from (66 ish)383 pick up , 318 66/68 flywheel re balanced to 400 weight and BB starter for the Bell.Never got original flywheel or starter with bell housing. I have a Bell housing from 361 Industrial (64to 68 C series ) application with matching flywheel that was installed on same motor. If I match the 361 flywheel to a 318 flywheel for a 66/68 pickup the diameters are different leading me to believe they're is a bell housing difference.
I might fiddle with it one day on a mock up motor to see what is different.

Only real difference between a CAR 361 and 383 is the pistons. Everything else swaps out. I have the factory 361 in my '66 Coronet 500, and it's the very same as a car 383. The 361 was used in cars from 1958 through 1966. Trucks used the truck 361 in medium-duty applications and motor homes through 1978 (1979 in Class C motorhome chassis).

The TRUCK 361 has an EIGHT-hole crank versus a six-hole on the others, plus the mentioned heads, exhaust manifolds and water pump housing. The 413 TRUCK shares those same commonalities with a 361 TRUCK. I'm about 98% sure the bellhousing is different, too, because of the crank end that sticks out a little further than the car. I used to have pictures that showed the differences, but I'm afraid those are long gone.

This is from first hand experiance, and understand there are a lot of things that are not by the books, however I have TWO of these bell / flywheel sets now; and they both need the extended flange, 8 bolt crank. I can post photos for comparison if it would help.
There is a B and a RB crank out there, so you can build from one of these, but the 361 crank cost we found was close to 300.00 plus 100.00 core. May still pony up for a crank and build a 400, but the lack of ability to 'swap' to an existing engine but a dampner on the fire here.

Casting numbers from someone's scan, there may be more.

Casting#
2206157 = 361 FORGED 1960-78 Truck 8 Bolt Ext. Flange
1851436 = 413 FORGED 1960-77 Truck 8 Bolt Ext. flange

I'll go look at the crank, flywheel and bell in the shed, now that the sun is up and see what it is. Its all in parts, down to a short block, on a cart, so easy to see everything. Have a car 413 sitting on a cart next to it, so can easily compare the bell casting number. The 413 came out of a 63 crewcab with NP 420.

I have a flywheel/bellhousing supposedly from a 76 S600 school bus 361. It is 6 bolt, not 8.

Upon inspection, the flywheel is 8 bolt, still bolted to the crank and away from the block. The bell is open and fits over the flywheel, like normal, not between the flywheel and block. According to the FSM, the industrial 361 and 413 are similar.
Does the 383 bell interchange with the 440 and the car 413?

[712edf]

My "361" hydraulic bell (1976) also uses 4" long bolts to block, and it fits to my 67 440 perfect, starter/flywheel & all.

What's the casting number on your bell?

Bucky

[PwrWgnDrvr]

Best I can see it right now, 93961

[712edf]

Does it look similar to this one?

Bucky

[712edf]

Another shot.

I believe my flywheel has 158 teeth. I got the flywheel/bell/PP/disc/fork & NP540 all as package deal.

Looks nothing like that at all, other than the 2 bolts on top. Mine has the std hydro clutch slave cylinder and clutch fork on the right side, no opening on the left.

[712edf]

I kinda figured that.

I really can't say if your bell is same as what the 383 (or 413) used. These are the only other two B/RB blocks that came in the hydro years.

For the record I think I paid about $400 for my set-up, plus maybe that again for the transmission that was once hooked to it.

Found this about the casting number above:

Apparently 361/413/383 bells are all the same

[hitparader]

On the intake, I am guessing it is casting #2206000, if not please post it.
