There is no honest way to determine the HP of an engine without knowing the specifics. The camshaft specs, the cylinder head specs (ported? Valve sizes? Valve springs? ) , the piston type (flat top, dome, dish, etc) etc. They can range from 150 HP to as much as 400, though the 400 would take an incredible amount of money. I know this is an old question, but the SA answer that was previously here was insulting.
it depands on the camshaft and heads. with 30 over windsor it should make at least 370 horsepower with aftermaket camshaft
In the mid 300 ish Hp
All else being equal, about 10 more than it had before.
Horsepower is simply a measure of the rate at which work is done. Any physical work done over a specific period of time will yield a calculation of the work performed, and that's called horsepower.
Sounds like a 343 to me. But for parts its a 283 bored 60 over
its called nothing because you wouldn't have a ENGINE left if you bored it 4" over
That would be called a Chevy 307 bored .40 over.
A 427 bored .60 over is 438.8572417 or basically a 439.
A 262 bored 30 over.
a bored over 305 The displacement is now 312.423
a Chevy 350 bored .060 over would be 360.4 cubic inches
That implies that the cylinders have been bored .090" oversize.
Get a make over.
How many cubic inches is my 340 bored .30 0ver ?
Each cylinder has been re-bored to a diameter .030" larger than it came from the factory. .030 oversize isn't much. It's done to correct slight cylinder tapering and to put the engine back into condition that it will last. It really isn't enough size difference to produce noticably more horsepower. Note that when the cylinder is bored .030 over, you'll also need pistons and rings that are manufactured to that size.
A 289 bored .030 over.
No a 383 is a 350 with a 400 crank. A 350 bored 60 over is 361 cubes.
The bore adds about 10 cu. inches to make it a 337
Produce more HP depending on much much they were bored. The engine can generally be bored up to .060 over in most cases.
over 9000 horsepower
Service factor is gearbox horsepower rating over motor horsepower.
