As for your other question it really depends on what you consider modified...Against what was traditionally called " modified " in the industry my Clocked engines are quite different...Generally speaking the traditional modified engines the work is focused around smoothing out the flow pathways of the mixture, adding guide channels to the exterior of the ports (Fangs,scallops etc ), turbo scoops on the crank face, polishing the sleeve...Usually very visible to the naked eye........ My Clocked engines have almost no changes you can see with the naked eye, as all my work is focused on the ports themselves, altering not only the port timings but also the port angles and volumes...Pretty much unless you know what you are looking for my work is almost invisible.......Far less impressive to look at then "Traditional" mods..........However in terms of affects on performance my style of modifications deliver far more radical changes to the engine, with far greater gains in both power and RPM........Of course this is all relative to how you define the terms.....
