We have recently pulled a 363 engine out of an old straight truck and i was wonderin if this engine is worth anything or should it just be scrapped? it has a holley carb on it. Just wondering thanks

MylilBowTie · 07-28-2007, 03:32 PM

Got any PICs of this engine?

scotty101 · 07-29-2007, 08:49 AM

I will try get some up today or tomorrow.

ont_guy_38 · 07-29-2007, 09:19 AM

They were 366 cubic inches and is it worth anything?.Probably not to the average person but you never know till you advertise it for sale

ChaseDale3and8 · 07-29-2007, 10:32 AM

Those were a big block that were used in the C-60 dump trucks and in school buses I believe. I don't think that they are really worth a whole lot but somebody out there might want it so I'd advertise it for sale and see if anybody wants it before I'd scrap it. ...Joe

scotty101 · 07-29-2007, 03:18 PM

yeah it is a 366 not a 363 sorry for the confusion i ment to ask along time ago but never got around to it and now i had a mental lasps on the last number. but that is what i was wondering. thanks and this engine came out of a old feed truck. so what about a holley carb off of it do they fit on a 350? of 305 or are they different bolt patterns? here are some pics

MylilBowTie · 07-29-2007, 03:47 PM

The carb will bolt up. Depending on what type of intake you have you may need an adapter. The distributor, air cleaner assy, alternator will also work. May have to remove the pulley on the alternator if you don't have a serpentine pulley setup. Some of the later 85-87? years had a serpentine and v-belt.

Pyrotechnic · 07-29-2007, 04:40 PM

Thats a Target Master so it's obviously been rebuilt.

The 366 was a tall deck, small bore big block. It's bigger brother, the 427T was a 427 with a tall deck, which made it popular with racers because you could get larger displacements without paying big bucks for a tall deck aftermarket block. The 366 isn't really valued though because the bore is too small for performance purposes. The bore is smaller than that or a small block 350.

It IS a very strong motor though. The pistons have an extra ring for durability because they were designed for the C60 medium duty trucks. It's a very low revving motor. The valves float at around 4000 RPM. Tons of torque though

If you got it and it's a good running motor with lots of life left, I say run it. It'll be perfect for pushing a highway gears like 3.08's down the road since it's got so much torque. Would be good for towing too. If it's a low miles motor, then it's going to last you a LONG time.

scotty101 · 07-29-2007, 04:57 PM

would a double stack air filter like that fit on a 350 or is that a pointess swap? vs. the stock air intake. thanks for the info on it, it is very intrestin and helpful i dont know alot about engines yet so i am trying to learn as much as i can

scotto0609 · 07-29-2007, 08:57 PM

I have a 366 in my dually and it runs nice. Nice low end torque but runs outta steam after 3500 rpm. It ctually runs so nice that I dont want to take it out and fix the rear main seal,so I constantly put oil in it!

liljon285 · 07-29-2007, 09:13 PM

So is it diesel or gas...if its gas then its a bbc right? I wouldnt mind building one...get a lot of unique rep. out of it!

78chev · 07-29-2007, 09:28 PM

Distributer means gas, right?

dswancutt · 07-29-2007, 09:40 PM

Sounds like you live in farm country, so if it is a good running motor and doesn't use oil, should be easy to get rid of as there are a lot of Chevy and GMC trucks that are used as farm truck. Just need to advertise it where farmers and such can see it if you want to get rid of it.

liljon285 · 07-29-2007, 09:43 PM

Oh wow it was right there lol im blind! So is it considered a big block or small?

liljon285 · 07-29-2007, 09:55 PM

oh OK it is a big block wow thats small...i would like to buy it and build it but !. i dont have the money lol and @. from eerybodys comments it dont think thats the best thing to do...and plus where do u find the parts for it!?

78chev · 07-29-2007, 10:04 PM

Hey, was'nt tryin to be mean. I was a little confused too b/c long stroke & small bore (relatively) usually means diesel.

Srubydo1986 · 07-29-2007, 10:29 PM

ya its gas and i think it kinda cool ive never heard of one

longhorn71 · 07-30-2007, 09:54 PM

the Crank in all the big block are the same as well

Yankeelights · 07-30-2007, 10:00 PM

Kool engine ... if I had it I'd have to drop it into something.
