Red face Chevy 366 Big Block

HAS ANYONE HERD OF A CHEVY 366 BIGBLOCK?
I JUST TRADED OFF ONE OF MY OLD BOATS
( YOU KNOW THE PROJECT THAT NEVER HAPPENS)
A 1964 16FT GLASSTRON.
ANYHOW THE GUY SAID IT WAS A CHEVY 366 BIG BLOCK
( YES IT RUNS, I HEARD IT RUNNING THEN PULLEDE IT)
BUT AS I WAS PULLING THIS BEAST FROM WHAT WAS LEFT OF A TWO TON CHEVY LONG BOX FRAME,
( REALY , IT WAS JUST FRAME ON BLOCKS WITH COMPLETE MOTOR).
WITH OUT LETTING ON TO WHAT THOUGHT WAS A 400 BIG BLOCK
WHAT I NEED TO KNOW IS , IS THERE A WAY TO TELL THE DIFFRENTS AND WHAT CAN BE DONE TO ONE. THANK GUYS.
JAMES

Yes, its a dump truck engine. Same stroke as a 427 but very small bore. Heads have a very small chamber. These engines would run forever. Only way to tell is to pop a head off and look at the bore.

Think twice before inserting money into a 366!

sandflea,
why do you say that? i got nothing in it , nada , zipp not a red greasy cent. i'm thinking of boring it to a 427, 1/4 race cam, 427 heads and so on. boring would be done free and could, more then likely get heads and cam dirt cheap? so please tell me more on you thoughts. before the facts or i spend money. JAMES

366's had no cylinder wall thickness to go 4.250. Pistons will be truck only stuff, 4 ring and heavy. If you did go say 80 over it would be a custom. I would keep the rods and crank and look for a 454 block and make a 427.

a 366 has a bore size of 3.935, a 427 has a 4.250 bore, and I don`t know of any big block that will bore 0.315 over and still have any bore left. The 366 was made for work trucks where low speed torque was needed, these engines are famous for burning a hole in the pistons due to high cylinder heat from such a small bore and a long stroke. I also don`t know of any high performance big block chevy heads that are "dirt cheap" horsepower costs money, how fast do you want to go? lastly, don`t waste your time or your money on a 366, why spend the money on a 366 when you could invest the same amount of money into a small block 350 and blow the 366`s doors off with less cubic inches?

Thanks fellows for piping in and giving some info. I would also like to add that the truck blocks had a deck height of 10.2 compared to the standard height of 9.8. That means the heads will be situated wider and taller in the car. The headers or exhaust might hit the floor boards, you will need spacers for the intake manifold and the big Chevy valve cover/ power brake booster clearance will get ever so tighter! I know of a few 366s and a 454. But, I can make such killer power with such little money with a Stroker 383-I have yet to switch to a big block.

Something I'm not understanding here.........Everyone says the 366 is crap, build a 383 instead...... A 383 is a 4" bore 350 block, with a 3.75" 400 crank. The 366 already has a 3.75" stroke, and the bore only needs .065" taken out to make an even 4". A cheap small block 350 piston could even be used in the 366. A 6" rod 350 uses a 1.260" pin height. That piston used with a 7.1" rod (Talk about pushing the long rod theory to the limit) would put you in the ballpark depending on what your deck measures. A small cut off the piston tops may be needed to get a zero deck. We are talking about the same motor in a bigger, stronger package.................

Heads........The 366 did come with heads that where "Small" for a big block. They aren't all that small for a small block sized motor. A stock oval port head will flow 250cfm, easy.

You will have the weight penalty of the big block. Every article I have ever seen, where a Big-Block vs. Small-Block shoot out is is done, the big block always wins. More horsepower, more torque, and quicker drag strip times. The big block was able to make the extra power needed to carry the added weight.

I don't see any reason to not use the 366 in a street rod application. Cost wise, with a free motor, he isn't going to have much more in it than if he where to build a 383 small block. Dan

Dan, piston for a SBC can not be used due to the valve pockets being different. Also pin size on a SBC is .927 and and BBC is .990" 366 is a good dump truck engine.
