Combination is very important
Backpressure compression
Turbo and the list goes on.
I don't know how high you plan on spinning what I do know with the new turbos now we make big power and it comes on really early
I'm liking what I'm seeing there😉
When using those ma heads just choose your cam and spring pressures wisely
Meaning don't go too wild those casting have been known to break.
I know that's what you have but I'm not of fan of them nor the original champion castings for 1000hp.
You can do the...
Any head can be run on the street.
The point of running a stage 2 head and block is flow and the ability to create power at a higher rpm.
A stage 2 motor sings at a higher rpm.
With that said a 200 will not be happy if you choose to spin it at 7500 to 9000rpm.
So that is not the tranny to run...
The problem is the parts
Most manufacturers are phasing out old obsolete wheels seals and shafts.
They are tooling up for the newer designs.
When you start factoring in labor these rebuilt units aren't that much cheaper than a new journal bearing unit
There is no way they will not move their inventory in favor of someone requesting a better exhaust wheel.
This is the business decision that is made way higher up.
Trust me the designers know where the limitations are.
Other companies have redesigned their compressors and turbine wheels to set...
