Wiki says they were only available in medium duty trucks and school buses. What is this one in? And why buy such an oddball instead of a good 396?

You need the block number, can't tell just by looks... I can tell you this, that is one air starved motor.

That is the right application for that engine for sure. Note the HEI ignition and Holley carb. I would suspect that it has a governor built in unless it has been removed. Should work good for a low cost power source. |

why the 366? Tall deck block can make parts expensive. A 454 or 396 can be built to move just about whatever you put it into, for less. I'd personally stay with a more common displacement motor, but hey that's me (I'm a big fan of the 454 if you notice my name  )
But like others have said, BBC mostly have the same external dimensions so get the casting numbers and run them. From what I remember the 366 has a forged crank and strong rods so that's a plus. |

I've also got size constraints as well. Any engine SBC size would do. If you're looking for torque you're better off with the BBC, because trucks, especially heavy trucks like armored trucks that require lots of torque to get them moving.. If the 366 is the same physical dimensions as other BBCs, why not look for a truck application 454 and have an engine that will work less hard to do the same job as the 366? Going to an SBC would mean working that engine harder to get comparable torque numbers and things like gearing changes might be needed to have the engine working in the right rpm range to most efficiently/effectively provide the power levels you'll need. I know that at one point all the step vans the AF used for aircraft maintenance activities used industrial (no emissions) 454 Chevies. When they would reach the end of their lives, there were always several GIs trying to outbid each other at the DRMO auctions to get those engines and TH-400 transmissions for their race car and hot rod projects. |

Agree that the application is right.
I had several in 70 series dump truck applications in the mid eighties. Only problems we had were cam lobes rounding off in a couple of them. Otherwise they seemed as good as anything else we were running at the time. Interesting sounding project.............. |

The one I had, had dual thermostats and a dual housing that bolted on top of the intake. That one looks like it has that.
Looks just like the 366BBC I drove everyday for years. Every day I tried to blow it up and every day i made it home. I wanted it in my Camaro. |

Yes, it looks like a 366 BBC truck motor.
Keep in mind: Taller deck height (10.2"). That means that you're going to want to hold on to all those brackets, and the intake manifold. Aftermarket intake mannies (for passenger BBCs) won't fit on these without spacers. That motor will have tiny little intake and exhaust passages in the heads. That's really good for what these motors do. You'll want the heads. Another major difference between the truck engines and the passenger engines (BBC): The truck pistons have an extra compression ring, for a total of 4 ring lands, vice 3 in passenger BBCs...another plus for a serious "truck" motor. Should have 4-bolt mains and a steel crank. Freshen the motor up--and you're going to want to have the heads upgraded for unleaded gas--but leave it as a truck motor, and you'll be fine. Oh--get the exhaust manifolds, too. Not sure of your application, but that taller deck height makes most passenger BBC headers too "short" for their intended chassis. |

87% probability that it's a 366. Very common in medium/heavy GM trucks. Low RPM/high torque engine. 1984 heads should be fine with unleaded fuel. If it runs good; clean and paint, install as is.

Truck blocks have about a .400 taller deck to accommodate the extra piston ring . You can see the difference when side-by-side by looking at the top water pump bolt hole and it's distance between it and the deck .
There are 366 and 427 models , they all use a similar forged steel crank , same main and rod journals , same stroke . The 366/427 cranks are the same forged cranks you'd find in a 396/402 and 427 passenger motors , also the same forged rods . All that changes is the bore ... The 454 is the oddball with the 4.250 bore but with a longer stroke . Slight balance issues might arise , but when re-building these old mills , you should always have them balanced , anyways . Most everything is swappable with other big blocks , except the push rods and pistons . The blocks on many of the 366's have extremely thick cylinder walls , and many are thick enough to overbore to 4.250 bore , making it a 427 ....but you really want to sonic check them for core shift in production . Every truck block I ever saw was a 4-bolt main. That's all I can remember about BBC mills from my years of machining them  |

Quote HistoryQuoted: You need the block number, can't tell just by looks..............  But , like I mentioned above , if you know what you're looking at , you can see if its a truck block by the space between the deck and the top water pump bolt hole on the left/driver's side.  You could very well have a 427 truck motor and not be able to tell without looking at the bore , either by pulling the pan or a head , or deciphering the RPO/ Casting numbers. And if I was pulling a motor to swap into something , there would be NO WAY that I wouldnt pull the pan while it's out , and be looking at a few bearings ,a couple rods and a couple mains , one of which would be the rear main to also examine the thrust , and installing a new Melling oil pump (std flow and press) as well as a new Cloyes timing set . I'd also change out the rear main seal , too , with a modern replacement . They are cheap insurance and too easy to do with the engine on a stand or hanging from the crane . |

Armored vehicle you say? Ditch the Chevy and get a real AFV motor....
 The Ford GAA engine is an all-aluminum, 32 valve, DOHC, 60-degree V8 engine produced by the Ford Motor Company during World War II. It featured twin Stromberg NA-Y5-G carburetors, dual magnetos and twin spark plugs making up a full dual ignition system, and crossflow induction. The GAA was used to power several models and derivatives of the M4A3 Sherman tank. The engine displaces 1,100 cu in (18 l) and puts out over 1000 ft lbs of torque from idle to 2600 rpm. Maximum rated horsepower was 525@2800 rpm though most models were rated at 450HP. |

No problem, I keep it handy on my phone as a reference for when I'm out and about scrounging parts or horse-trading. I did lose out on a freebie high-compression 327 one time because I was honest...guy had a "350" he wanted to get rid of. I ran the numbers and came up with a 327, so I informed the owner to be honest, who then immediately changed his welching mind.
