Headers for a 410 stroker?

[brewil]

My 410 stroker will be in a right hand drive vehicle so I will either have to get
Aussie made tri-y headers or shorties. Do the shorty headers have a major power loss??

Yes…… You will see a power loss going from a Tri-y to a shorty. Hard to say how much.

I know I lost 13 mph in the 1/4 when I went from hooker super comps to to 340 manifolds but mine is a very high RPM build.

Don't know what your car is or what your plans for it are, but you could probably get away with a set of fenderwell headers if the engine offset is the same as a US spec car.

Daily driver-auto with a 410 stroker engine which will run mid range torque.
