Big Block or Small Block? help please

What is the difference between a big block and a small block besides overall size? What are the advantages and disadvantages of both, and what are they both generally used for (ie: which is better for daily driver, racing, etc).

I am starting my first project truck which is a '69 Chevy C10 Fleetside, bone stock, and im looking at an engine swap. Also, as money is a factor, would I be beter off going with a Chevy, or perhaps an Olds, Cadillac, or some other brand?

Any engine size/displacement can be "purpose built", General rule of thumb, especially with chevy stuff is that, big blocks are a bit on the expensive side, but if built right, can give you gobs and gobs of monster torque on the street.

Small blocks are good for budget builds, but can also be built for decent power, but they tend to get more and more radical as they are reaching the big blocks potential.

My vote goes for the big block (even though I dont have one)




PS......this is going to be the start of a flame war, haha, the neverending debate.

CUL8r, do a search...this topic has been gone over more than once already. as far as whats best for your application....if the truck is already a small block, I personally would stay small block Chevy, there cheap, can build plenty of power. I love big blocks..I have a 454 in my 75 C-15... & wouldnt ever trade for anything else...cept maybe a bigger big block.so dont get me wrong...just dollar for dollar sbc are hard to beat

bb vs sb

The bb is not only bigger but 200 lbs heavier. In a vehicle such as a sb Vette where suspension is a key factor. The heavier motor will mess up the suspension. For a straight line drag car. There is no replacement for displacement. BB all the way. The best in between motor is the 400 sb. It's light and has close to the same torque as the bb.

ok so for my application I would be better off going with a smallblock, because Im going to be using this as a daily driver alot more then a strip truck. Another question. with a small budget, would I be better off looking for an engine from a donar car or just spending the cash on a new one. Is the cash I save on a used engine worth it?

That's another judgement call but I would go the donor car route.

Hi gang... I'm CUL8R's friend whos helping him on this project. I believe the current engine is an inline 6. no idea of its power output nor displacement.

Whats wrong with the engine? nothing that we couldn't fix... except for that fact that we want more POWER. hehe.

gas gas gas

With the current gas prices headed towards heaven, I would leave that inline 6 in there until i came across a 327sb. They are reasonable on gas for a small block and can be built to demand respect. I have a 350 in my 70 pickup and it drinks gas like its $.99/gal not what you want for a daily driver.

Ive said it before and ill say again nothing replaces displacement
a 69 chevy c 10 will handle just about any motor u want put in it as matter of fact Ive seen just about every brand of V8 in one of those old chevys
my first vehicle was a 70 chevy suburban 5 door w/ a 250 6 banger it was so slow that i got nicknamed after it "slowride"

if its just transportation leave the 6 more power chevy V8 look around for a running 400 small block
if your gonna tow anything w/some weight BIG BLOCK
keep in mind gas ain't getting cheaper especially in the great white north eh?
my 79 ford gets 5 MPG down hill but when it comes down to hooking up my 20' flatbed and hauling 10'000lbs of porcelain tile its right there 300,000miles still haulin and buyin gas

good luck with whatever you choose
slowride66
ps dose it have that 4 wheel coil spring suspension? those things were like factory ladder bars
in my opinion 67 to 72 was the pinnacle for chevy trucks you still see lots on the road
BIG BLOCK

Your right trucks are popular and can be very valuable if done right. Heres a pic of my daily driver plan on doing a frame off in the near future.

For a daily driver, with a little strip time, I'd vote with Derky, on waiting for a 327. They can be built to make acceptable mileage, and still take ear-bleed rpm, if you build it right.

Personally, I voted for a 402 BB, into my 62 C-20. It is going to be my regular rig for my 5th wheel rv. No doubt that a BBC will out torque a smallblock any given day.

My 1-ton wrecker has a 350, and is nothing impressive, until you factor in, that it weighs 9600lbs, full of fuel, and will still pull a similar vehicle up the highway, at 65mph. It makes around 8-10 mpg, loaded, or empty.

On the other hand, my 49 1 1/2 ton wrecker is running a worn out '69 250 6-banger, that uses oil like a fiend.(Mostly because I have flamethrowers out the dual 4" stacks) It will still drag almost anything, provided I can get tied on tight enough. A couple summers ago, I used it to pull a 12 ton sheepfoot roller around our local 1/2 mile dirt track. Those old inliners are hard to kill, if you keep enough oil and water in them.

no doubt keep them ol sixers oilin
an they'll run forever not enough power to blow them selves up

you can build a six to run like a small eight and build a small eight to run like a big one
like i said my first truck was a six and then all the rest were V8s the big blocks are the most fun to drive
there is not a lot of room around here to drive like that any more roads are too crowded but i still give it all i got when i can up to the speed limit
im a safe driver now
it says so on my license
