You can take a 103 and make good power never said you could not. But to get there you will need to change pistons do head work raise compression cams exhaust tuner etc.
This our basic 107 kit. You can build off of. We are just like other shops we offer bolt on kits and we can custom build you a kit from 74" to 145" motor.
And rule of thumb 1 HP per cubic.
For some people its a pain to remove cylinders send them out bore and hone etc. Some people prefer a drop in kit Done.........
You have many options out there for engine kits it your choice on what you want to do.
But to accuse me of being dirty........than your calling other shops and vendors here and all over that have very similar kits the same.
Also keep in mind this a 113 inch and 114 inch kit.......... you quoted...
If you would like to talk to me please call me would be more than happy to answer any questions you have.
