Very little data is provided. I was just wondering, does anyone know if the short block of the Sabrina engines is the same as the stock TR3A block with a custom head or were they custom blocks as well? I have access to laser scanning, CAD and 5-axis milling. I was wondering if a guy could laser scan a Sabrina head, get it cast and then 5-axis machine it and shoehorn it under the bonnet of a TR3A. If it was possible, someone would have probably already did it.</div><div id="yui_3_16_0_ym19_1_1461867310582_7195" dir="ltr"> Does anyone know if a hot TR3 cam would have worked in a Sabrina or if it was some custom cam size/length? It seems like Triumph would have raided the parts bins for parts rather than get too sophisticated. <br></div><div id="yui_3_16_0_ym19_1_1461867310582_7165" dir="ltr"> Does anyone know if an original Sabrina engine still exists?
