Science is science,it trumps comments.Model A engine CFM and single Holley 94/stromberg 97 CFM flow are very close..Jetted correctly with the right power valve it meets the engines air flow capacity spot on,yielding the engines best performance. What you are planning to do is noble,but you're denying yourself one of the two areas that has the most impact on the model a's engine performance,compression and fuel.You're raising compression,raise fuel..and do something about exhaust,a straight pipe with a resonator off the model a exhaust manifold will let it breathe some.
