Small block is around 575 and Big Blocks around 675. 454's are just a fuzz lighter due to bore larger bore size. Both weights are for all iron engines, block and heads, not aluminum heads or blocks. TL
yes there is.
For complete engines, the weight of the average (stock) 400 Pontiac at about 650 lbs. is roughly between the average (stock) Chevy small block at about 575 lbs. and the average (stock) Chevy big block at about 680-685 lbs..
There is no difference what so ever. Same engines.
the weight of my 427 Chevy big block. Which is the same as the 396, 454. This is a bare block we are speaking about. the total weight of a bare block Is right at 200 pounds.
Many. 348 would be a small block, whereas the 454 is a big block.
Chevrolet never made a 354 big block. So is say the difference is that a 496 is real and 354 is not. there is talk of a 354 small block but they are all from UK and id be inclined to say they are actually talking about a 355.
350, to 400lbs.
ON LATER MODELS LOOK AT THE REAR OF THE BLOCK NEAR THE DISTRIBUTOR AND IT WILL HAVE 5.0 OF 5.7 CAST INTO THE BLOCK
weight. the aluminum block is lighter therefore it uses less fuel and the vehicle is faster.
the big Chevy truck rod is bigger than a passenger car rod.
