Ok. So seeing that my engine isn't 'smog restricted' then I shouldn't have any problems?

u will be fine

I run twin kads and a 009 and they run fine, I've been lucky enough never to experience the Kadron Flat Spot Syndrome.

Engine is an 1835 w counterweighted crank, balanced, 040 heads and HSC Stage 2 cam.

Kads are great on motors up to my size, but I wouldnt run them on anything bigger without looking at Jet sizes and maybe trying to get some bigger venturis.

will be suitable, as long as the Kads have not been rejetted to suit a larger engine.

beautiful. thanks guys

She'll run sweet, I've go the same combo on the KG.
