    <p>the twin SUs and 4-2-1 Eurospec exhaust will definitely be a
      noticable improvement.</p>
    <p>Late 70's spits were de-tuned (smog regs) in the US and choked
      down with the single ZS carb , somewhere around 58 hp.<br>
      Just the carbs and exhaust change puts you back to near 75HP.....
      and before the cam change!</p>

            Albeit very limited, the SU carb proved a bit difficult to
            lean out and that’s why Spitfires from either 1969 or 1970
            model year used a single Stromberg. My personal opinion is
            the Mk3 Spitfire with the 1296 8 port head is the Best Buy,
            hotly followed by the 1296 Mk4. The 1500 engine is

            rebuilt/cared for/completely knackered - were all the same,
            I.e. seriously disappointing and that same engine in the
            Midget made that great little car something that is best
            forgotten.
