10hp
yes
bout 10 to 25. depending on what size of motor
adding headers will allow engine to breath better and boost up horsepower but not by much, headers also make you vehicle louder with pipes.
20-25 as a rule of thumb. More with good heads.
if you can find the hp. of the eng., you can add between 12-20 more hp. for the headers.
Not enough to even notice.
Not much, I wouldnt exspect it to b the diffrence from burnin rubber or not, maybe 5 - 10
Start with a cold air intake, then add headers. If you want 100 or more horsepower instantly add nitrous
Headers can add approximately 10 to 20 horsepower to a 454 engine, depending on various factors such as the design of the headers, the engine's overall condition, and supporting modifications like carburetors and exhaust systems. Properly tuned headers improve exhaust flow and reduce back pressure, which enhances engine performance. However, the actual horsepower gain can vary based on the specific setup and tuning of the engine.
There are too many variables that determine what hp increase headers will give. Engine size, carbed,f.i.,stock,hi perforforman ce,car weight,the list goes on and on....
carb, cam, intake, headers, heads, msd igntion, or a 350
You would probably only get 5-10hp at the crank from installing both, depending on brand and other modifications.
