Yes it does. Boring it at all has an effect on it. However, a .040 overbore won't hurt anything. Most blocks can easily handle a .060 overbore, so you should be just fine at .040.
Typically if the motor has been bored the top of the replacement pistons will have it stamped on top of them. for example if bored 0.30 over this will be on the top of the pistons.
Pistons don't have bots. More information is needed.
Its a 355 cubic inch
Need alot more information IE what intake? carberated tbi? what pistons? rotating assembly? but jus very ruff estimate should be around 280-300 flywheel hp well the motor is a late 70`s motor carburetad slightly better pistons than factory dual plain elderbrock intake with long tube headers.
The Chevy Crate engine is an engine that is custom built. They usually have more power and are made from the original motor but bored out and modified.
the standard motor that it came with off the assembly line was a classic 350. but if its a used truck it could have been bored futher.
could cause internal damage to valves and or pistons !
Take off a cylinder head and measure the diameter of the bore.
It had a turbine engine, not a motor with pistons.
They are basically the same heads, If the 93 350 is a vortex motor.
a bored out 350 blockThat answer is right, but it did not answer your question completely.A 355 is a 350 block that has been bored .030 / thousand oversize from factory stock bore. Nothing special.
I've seen pistons that were .060" over. Any more than that would probably not last very long.
