Firstly let me commend the regular contributors and everyone else on some fantastic threads lately, very informative to someone in the process of building a big bore B20
In the meantime I recently bought a very nice 66 121 that has been fitted with a new D cam and followers and twin SU HS6, when I got it, it had a huge flat spot at lower revs, I replaced the RL needles with some SM's I had, put a 2 inch exhaust on , 1 muffler, and advanced the timing a bit, that made a big improvement, the engine has lots of power ( well enough for how I use this car ) at higher revs but still not much midrange power, the carbs have been rebuilt and are sound, the engine is low mileage and feels very sound.
Are there some more suitable needles? any other possibilities?
Or do i just put in a B20?
Thanks
Hans
