How much does this cost?
How much HP can it make?

I am looking for dependable high HP NA for my race car.
I want something that will last, I don't want it to be too extreme and hard on engine parts, but I want it to make some power though.

We are hoping to be at about 800rwhp NA, we will be testing with different intake setups, Ported GM LS7, Fast LSXR, Straight runner fuel injection, and we will be testing multiple camshafts. Will have more info as it happens.

As for cost we aren't sure yet, still working on final parts cost for the build.

Thank you all for your interest on our newest motor project.
The price is still being finalized.
I will add pictures and hp numbers of the motor when we are done testing cam profiles on our engine dyno.
For now I have pictures of the intake manifold spacers needed to work with the taller deck height of the block.
Thanks. Chris at MTI Racing.
