As a VERY BASIC rule of thumb, 1 HP per CID, all else being equal. In this case, your talking 44 cubic inches or 44 HP. That's "pretty close" to what Brad said; 2 1/2 tenths. And he has real world experience. That just allows you to do some quick calculations to determine if the CID increase cancells out the HP or weight increase. And of course you should easily make 1.25+ HP per CID for any class engine.
