Hi Graeme, try a 750 double pumper Holley and you will smoke those tyres . I had a 650 on my 400 Trans-Am and it works. Cheers Rassie.

Hi Graeme,

First off, piss cool car!!!!! My 2 cents on the Rochester, and it really is just 2 cents because I really don't know much/anything about tuning a carburetor, is that they are really not that difficult to rebuild. When I had the monaro one of the first things I did was to buy the Hayens manual on the quadrajet as well as a kit from CarburetorCity in joburg somewhere and started rebuilding the roch. The biggest problem I had was that my roch's airhorn plate thingy was sligthly warped. But half an hour or so with some fine grit water sanding paper on a piece of glass and it was almost as good as new. The kit really installed easily, and afterwards even the power pump or accelerator pump thingy worked like a charm and at least removed the hesitancy when blipping the throttle.

Anyway, I just think that if I could semi successfully rebuild a rochester then basically ANYBODY could. (Ps and my neighbours will confess that I do like it a lot when the secondaries are sucked open on highish revs!!!!!)

Enjoy the day, Stephan.

I hear as far as ease of tuning the Edelbrock carbs are the best but I am far from a carb expert...
